Figure 9 A simplified block diagram is shown schematically. Figure 10 An example of the application is shown schematically. Detailed Implementation

[0023] For some examples, see Figure 1 , 2This relates to a method for a chip system 10, such as a computer-implemented method, the chip system having a carrier, such as a substrate 12, having at least one first component 14-1 disposed on the carrier 12, and having a communication interface KS for transmitting a first signal SIG-1 between the first component 14-1 and at least one second component 14-2, such as the chip system 10. Exemplarily, the second component 14-2 is also disposed on the carrier 12. See also [link to method description]. Figure 2 It has the following features: providing a second signal SIG-2 of 100 by means of a spread spectrum method, via at least one signal line SL of the communication interface KS ( Figure 1 Transmit the second signal SIG-2 of 102.

[0024] For example, the communication interface KS is of type UCIe or compatible with it, and has, for example, multiple signal lines, by means of which one or more communication channels of type UCIe mainband or UCIe sideband can be implemented, wherein, for example, at least one of the aforementioned signal lines SL belongs to the multiple signal lines.

[0025] For example, the first signal SIG-1 is a signal transmitted via the communication interface KS according to the UCIe standard, such as via the UCIe main band channel or the UCIe sideband channel, wherein the first signal SIG-1 is transmitted, for example, within a frequency range that conforms to the UCIe standard.

[0026] See in some examples Figure 1 The first component 14-1 and / or the second component 14-2 are configured to have at least one of the following elements: a) a core, or b) an interlayer.

[0027] See in some examples Figure 2 The setting, transmission 102 includes at least one of the following: a) transmitting the second signal SIG-2 at least in time overlapping with the transmission of the first signal SIG-1, for example, simultaneously; or b) transmitting the second signal SIG-2 in a frequency range that at least overlaps with, for example, includes a frequency range associated with the first signal (e.g., a frequency range conforming to the UCIe standard).

[0028] For example, in addition to the first signal SIG-1, a useful signal SIG-N with an associated useful signal spectrum is also transmitted via the communication interface KS. Figure 1The signal SIG-N can be transformed into the second signal SIG-2 using a spread spectrum method, such that the second signal SIG-2 has a significantly larger bandwidth than the spectrum of the useful signal, for example, many times larger. In this way, the signal energy components of the useful signal SIG-N are distributed over the larger bandwidth of the spread second signal SIG-2. In some examples, this makes it possible to transmit the second signal SIG-2 via the communication interface KS without, for example, interfering with the transmission of the first signal SIG-1, because the individual spectral components of the spread second signal SIG-2 are incorporated into, for example, the noise floor associated with the first signal SIG-1, such as background noise, or disappear therein, for example, they are undetectable or undetectable (e.g., without corresponding despreading), or at least do not significantly impair the associated signal components of the first signal SIG-1.

[0029] See in some examples Figure 2 The method includes, for example, providing 100: transforming a useful signal or the useful signal SIG-N into a second signal SIG-2.

[0030] In some examples, the spreading method is set to one or a combination of the following methods: a) direct sequence spreading, DSSS, b) chirped spreading. In some examples, different spreading methods than those described above may also be used.

[0031] See in some examples Figure 3 The method comprises: providing 110 or more second signals SIG-2a, SIG-2b (e.g., based on one or more useful signals) respectively by means of a spread spectrum method, via at least one signal line SL of the communication interface KS. Figure 1 ) Transmit the plurality of second signals SIG-2a, SIG-2b as described in 112.

[0032] See in some examples Figure 4 The method comprises: providing more than 120 second signals SIG-2a and SIG-2b (e.g., based on one or more useful signals) in different frequency ranges FB-a and FB-b respectively by means of a spread spectrum method, and transmitting more than 122 second signals SIG-2a and SIG-2b via at least one signal line SL of the communication interface KS.

[0033] See in some examples Figure 5 The method comprises: providing a second signal SIG-2 130 for transmission via at least two different signal lines SL-a, SL-b (e.g., two differential transmission lines) of a communication interface KS, and transmitting the second signal SIG-2 132 via the at least two different signal lines SL-a, SL-b.

[0034] In some examples, two different signal lines can also be different non-differential signal lines.

[0035] See in some examples Figure 6 The method includes: receiving 140 by means of a spread spectrum method (e.g., according to this disclosure, see example...). Figure 2 The signal SIG-SS, generated by (frame 100) and transmitted via at least one signal line SL of the communication interface KS, is despread, for example, by performing 142 despreading on the received signal, thereby obtaining, for example, the despread useful signal SIG-DS.

[0036] For some examples, see Figure 7 This relates to a chip system (see, for example) Figure 1 The method comprises: a chip system having a carrier, at least one first component disposed on the carrier, and a communication interface for transmitting a first signal between the first component and, for example, at least one second component of the chip system; wherein the method comprises: receiving a signal SIG-SS generated by means of a spread spectrum method and transmitted via at least one signal line SL of the communication interface KS; and performing despreading, for example, despreading processing, on the received signal SIG-SS.

[0037] See in some examples Figure 7 The method comprises at least one method according to this disclosure, for example, according to any one of claims 1 to 8. In other words, in some examples, the method may include, for example, providing 100 and transmitting 102 in addition to receiving 202 and despreading 202, for example, according to... Figure 1 ,etc.

[0038] For some examples, see Figure 8 This relates to an apparatus 300 for implementing the method according to the present disclosure.

[0039] In some examples, device 300 is configured, for example, to implement, according to Figure 2 , 3 At least some aspects of at least one of the graphs 4, 5, and 6.

[0040] In some examples, device 300 is configured, for example, to implement, at least according to Figure 7 At least some aspects.

[0041] In some examples, device 300 is configured, for example, to implement according to Figure 2 , 3 At least some aspects of at least one of the figures 4, 5, and 6, and for implementation at least according to Figure 7At least some aspects.

[0042] See in some examples Figure 8 The apparatus 300 includes: a computing device (“computer”) 302 having at least one computing core, and a storage device 304 associated with the computing device 302, the storage device being used to at least temporarily store at least one of the following: a) data DAT (e.g., data associated with at least one of a useful signal SIG-N or a second signal SIG-2 or a signal SIG-SS, SIG-DS), b) a computer program PRG, for example, for implementing the method according to the present disclosure.

[0043] In other examples, storage device 304 has: volatile memory (e.g., working memory (RAM)) 304a, and / or non-volatile (NVM) memory (e.g., flash EEPROM) 304b, or a combination of volatile memory and non-volatile memory, or a combination of other memory types not explicitly mentioned.

[0044] In other examples, device 300 is constructed as a hardware circuit, such as a purely hardware circuit (not shown).

[0045] For other examples, see Figure 8 The present invention relates to a computer-readable storage medium SM, comprising instructions PRG' which, when executed by a computer 302, cause the computer to perform the method according to the present disclosure.

[0046] Other examples relate to a computer program PRG, PRG', including instructions that, when implemented by computer 302, cause the computer to implement the method according to this disclosure.

[0047] Other examples relate to a data carrier signal (DCS) that represents and / or transmits a computer program (PRG) according to this disclosure. The data carrier signal (DCS) may, for example, be received via an optional data interface 306 of the device 300.

[0048] For some examples, see Figure 1 The present disclosure relates to a system, such as a chip system 10, having a carrier 12, at least one first component 14-1 disposed on the carrier 12, and a communication interface KS for transmitting a first signal SIG-1 between the first component 14-1 and, for example, at least one second component 14-2 of the chip system 10, the system having at least one device 300 according to the present disclosure.

[0049] For some examples, see Figure 1This relates to components 14-1, 14-2 for a system, such as a core system 10, said system having at least one device 300 according to the present disclosure. For example, the device 300 may be integrated into at least one of components 14-1, 14-2, or arranged, for example, on a carrier 12.

[0050] Other aspects and examples are described below, which may be combined individually or in any combination with at least one of the aspects and / or examples described above in other examples.

[0051] In some examples, such as the direct sequence spread spectrum (DSSS) method, a second signal SIG-2 is provided.

[0052] In some examples, the useful signal to be spread is SIG-N ( Figure 1 For example, it can be characterized by a bit sequence.

[0053] In some examples, DSSS spread spectrum can be implemented by performing bitwise logical operations (e.g., "XOR") with a bit sequence and a codeword of a pre-given or secret length (e.g., known only to the sender or the intended receiver). For example, in this way, a sequence of multiple bits with different values ​​(e.g., high / low or "1" / "0", etc.) is generated from a single original bit (i.e., one bit of the bit sequence of the useful signal SIG-N). Because in some examples, more signal changes (e.g., per unit of time) exist in the signal that is transformed in this manner, i.e., spread, a signal that is, relatively low-frequency (with smaller bandwidth) (e.g., the bit sequence corresponding to the useful signal) is converted into a relatively "high-frequency" (with larger bandwidth) signal. This in some examples makes it possible to utilize the entire signal spectrum (e.g., a communication interface), from high frequencies to low frequencies, for example, also for the relatively low-frequency or low-bit-rate useful signal SIG-N.

[0054] Because in some examples, the signal energy associated with the useful signal SIG-N remains constant, the signal energy of the second signal SIG-2 is distributed, for example, across the entire available / used spectrum. In this way, in some examples, many, for example, all, spectral components of the second signal SIG-2 are transmitted at energy levels that are, for example, close to or even lower than the noise level of, for example, the first signal SIG-1. In some examples, reconstructing the useful signal is still possible if the despreading matches the codeword used.

[0055] In some examples, the second signal SIG-2 may be combined with the first signal SIG-1, for example, superimposed on the first signal SIG-1, without impairing the first signal SIG-1.

[0056] As described above, the first signal SIG-1 is, for example, a signal compliant with the UCIe standard, and in some examples, the second signal SIG-2 can be combined with the UCIe signal and, for example, use the same signal lines as the UCIe signal without the UCIe signal being compromised.

[0057] When reconstructing the transmitted second signal SIG-2, i.e., at the receiving side, the same (e.g., potentially secret) codeword can be used for despreading. For example, despreading can be achieved by performing a new logical operation on the received second signal SIG-2 and the codeword, thereby obtaining, for example, the original useful signal SIG-N.

[0058] The following is an example of DSSS-based spread spectrum. For this example, consider a binary useful signal that can take the values ​​"1" or "0", where the codeword used for spread spectrum is, for example, "11000111". For a useful signal with a value of "0", a logical operation (Verodern) yields the bit sequence "11000111", and for a useful signal with a value of "1", the bit sequence "00111000". A re-logical operation on the codeword, as can be performed at the receiver for despreading, yields the bit sequence "00000000" for a useful signal with a value of "0" or a bit sequence of "11000111", which can be interpreted as "0" at the receiver, and the bit sequence "11111111" for a useful signal with a value of "1" or a bit sequence of "00111000", which can be interpreted as "1" at the receiver.

[0059] According to some examples, another variation of spread spectrum is chirped spread spectrum. Here, the signal bits associated with the useful signal SIG-N are encoded, for example, as (partial) frequency scans that form physical symbols, thereby converting the low-frequency signal into a region with a higher bandwidth (frequency spread). In some examples, at least one parameter of chirped spread spectrum can be predetermined: how the low-frequency portion of the useful signal SIG-N is distributed to higher frequencies during spread spectrum.

[0060] In other examples, the principle of chirped spread spectrum can be implemented multiple times, for example, for different target frequency ranges, which are respectively located within the total available frequency range (e.g., "bandwidth") of the communication interface KS, thereby enabling, for example, transmission via a single physical line SL ( Figure 1 ) or differential signal pairs, such as UCIe pairs, SL-a, SL-b ( Figure 5This can be used to achieve redundancy during communication, for example. In some examples, a single, "virtual" channel can be represented by dividing the available bandwidth on the relevant signal lines into multiple frequency bands.

[0061] In other examples, one or more spread-spectrum signals, such as second signals SIG-2a, SIG-2b, etc., can be transmitted via multiple (e.g., differential or non-differential) signal lines of the communication interface KS. In some examples, it is conceivable to transmit two spread-spectrum signals, for example, each via a signal line in a differential signal line.

[0062] The principles of this disclosure enable, in some examples, the transmission of information, such as control information, or information as a supplement to the secondary signal SIG-2 (e.g., regarding primary data communication aspects when using the first signal SIG-1), between different cores or core portions and / or other components, such as intermediate layers, without, for example, impairing existing transmissions of the first signal SIG-1, such as according to standards like UCIe.

[0063] The principles of this disclosure enable bypassing, for example, the underlying software stack and / or UCIe-ISO / OSI stack in some examples, because the second signal SIG-2 can be directly added to the PHY layer signal of an existing UCIe transceiver, for example, in the case of using analog and / or digital adder circuitry.

[0064] The principles of this disclosure enable efficient information exchange, for example, for safety measures or in applications such as motor vehicles, via a second signal SIG-2, without requiring modification of existing, potentially conventional UCIe components in the core system. For example, conventional UCIe-compatible cores can supplement the functionality of this disclosure by, for example, by incorporating at least one device 300 in a common target system.

[0065] The principles of this disclosure enable the transmission of the second signal SIG-2 in some examples in a manner transparent to conventional chips or intermediaries using the communication interface KS. This means that in some examples, conventional chips or intermediaries using the same communication interface KS, for example, also used to transmit the second signal SIG-2, cannot obtain information about the existence of the second signal SIG-2 or information about the second signal itself, because this information is, for example, hidden in the noise substrate due to spread spectrum and can only be reconstructed, for example, if the correct despreading method and the corresponding code are known.

[0066] The principles of this disclosure enable the implementation of additional services for a chip system in some examples, such as using a communication interface KS to relay a first signal SIG-1, for example, an existing communication stack (“stack”) that does not rely on a traditional UCIe communication partner.

[0067] The principles of this disclosure enable the use, for example, multiple uses of existing signal lines SL and components of said signal lines that are also used for the second signal SIG-2 (e.g., bumps for contacting the core with the interposer).

[0068] The principles of this disclosure enable safeguards to be implemented in some examples, such as by additionally using a second signal SIG-2 in addition to the first signal SIG-1 to maintain an alternative communication channel, which improves security against, for example, systemic failures compared to conventional UCIe communication.

[0069] Figure 9 The diagram schematically illustrates a simplified block diagram based on some examples. Component E1 represents a carrier, for example, in the form of a first interposer. Component E2 represents a second interposer, for example, a core portion package, with a UCIe-compliant or UCIe-compliant core E3, whose UCIe-PHY device is... Figure 9 The reference numeral E3a is used in the attached diagram. Component E10 indicates another UCIe-compliant or compliant chip.

[0070] Component a1 represents the attachment of core E3 or its UCIe-PHY device E3a to UCIe interface a3, through which two cores E2 and E10 can communicate with each other, for example in accordance with the UCIe specification, and see also, for example, according to Figure 1 The first signal is SIG-1.

[0071] Component E4 represents a means associated with, for example, transmitting and / or receiving spread-spectrum signals provided via UCIe interface a3, see, for example, according to Figure 1 The second signal SIG-2. Element E5 represents the spread spectrum according to this disclosure, and element E6 represents the corresponding despreading. The second signal a2 generated by means of spread spectrum E5, see also... Figure 1 The attached figure designation SIG-2 can be seen in some examples, see [link to example]. Figure 9The combination is performed using a combining device E7, for example, combining with signal a1 from the bit transport layer, such as the PHY layer, or the UCIe interface. In other words, in some examples, element E7 combines a conventional UCIe signal transmitted by chip E3 with a second signal SIG-2, a2 ​​provided by element E5. In some examples, the combination is performed by adding signals a1 and a2, wherein the combined signal, including, for example, the first signal SIG-1 (e.g., within a subband or frequency range conforming to the UCIe specification) and the second signal SIG-2 (e.g., within the (e.g., the entire) bandwidth of UCIe interface a3), is transmitted via at least one signal line of UCIe interface a3 to another chip E10.

[0072] The spread spectrum signal received by chip E2 via UCIe interface a3, for example, from another chip E10, is... Figure 9 This is indicated by arrow a4 and, for example, input to the despreading component E6. For instance, component E4 can serve at least temporarily as the useful signal SIG-N (see also...). Figure 1 The useful signal is transmitted via UCIe interface a3, at least temporarily using spread spectrum signals SIG-2 and SIG-SS, in accordance with the principles of this disclosure.

[0073] Figure 9 Component E11 represents the UCIe-PHY of core E10, such as component E3a similar to core E3, and arrow a5 represents a corresponding UCIe-compliant signal (e.g., the first signal SIG-1), which can be combined, if necessary, via combiner E13 with a second or additional spread-spectrum signal a6 provided in core E10 via component E12. In some examples, the combined signals a5, a6 can be transmitted from core E10 to intermediary layer E2 or intermediary cores E3, E4 via UCIe interface a3.

[0074] The spread spectrum signal received by the chip E10 (see, for example, according to Figure 9 Signal a2) can be input to the despreading unit E14, for example, as signal a7, and then exist in the core E10 as the reconstructed received useful signal a8.

[0075] According to Figure 9 In the above example, the two components E2 and E10 can both transmit (see arrows a2 and a6) and receive (see arrows a4 and a7) spread-spectrum signals. In other examples, it is also possible that a component, such as the interposer E2 or the core E3, provides and transmits the spread-spectrum signal, for example, only transmits (see arrow a2), however, for example, the interposer E2 is not provided with a despreading component E6 or receives the spread-spectrum signal.

[0076] For some examples, see Figure 10 The present disclosure relates to the use 400 of the method and / or apparatus 300 and / or system 10 and / or components 14-1, 14-2 and / or computer-readable storage medium SM and / or computer program PRG, PRG' and / or data carrier signal DCS according to the present disclosure, for at least one of the following: a) transmitting 401 at least one spread spectrum signal via communication interface KS, for example, at least temporarily overlapping with the transmission of the first signal SIG-1, for example, when using the same signal line SL. a) Perform simultaneously, b) Use at least one signal line SL multiple times, c) Add at least one additional signal to the first signal, d) Distribute the signal energy associated with the second signal SIG-2 to a frequency range that is relatively large compared to the frequency range associated with the first signal, e) Provide robust data transmission, f) Hide the second signal SIG-2, for example, in noise, g) Bypass the communication stack of the communication interface KS (for example, associated with one or more layers according to the ISO / OSI layer model), for example, a stack.

[0077] In some examples, the principles of this disclosure can be used to provide chip systems or other distributed embedded systems, in which, for example, an entire computing system is composed of multiple chips. Here, the chips may, for example, have different sizes, manufacturing techniques, and uses.

[0078] In some examples, the principles of this disclosure can be used to implement, for example, time monitoring across different cores, such as deadline monitoring, for example, when using the second signal SIG-2. Thus, in some examples, measures can be implemented, for example, to monitor the actual implementation time of each core, such as with respect to safety-critical deadlines, and to intervene, for example, at the computational task level, when deviations occur. In some examples, the principles of this disclosure can be used, for example, to transmit watchdog information and / or “heartbeat” signals between cores and / or intermediary layers and / or components of, for example, the core system, using the second signal SIG-2.

[0079] In some examples, the principles of this disclosure can be used, for example, by means of a second signal SIG-2, to transmit information for, for example, reconfiguration and / or rescheduling of computing tasks performed by different chips.

[0080] In some examples, the principles of this disclosure can be used, for example, in situations where there is redundancy in availability (e.g., multiple redundant cores are used for the same computational task), to exchange information about role consensus between different cores, for example, by means of a second signal SIG-2.

[0081] In some examples, the principles of this disclosure can be used, for example, by means of a second signal SIG-2, to exchange information for comparing, for example, redundant calculation results of different cores.

[0082] In some examples, the principles of this disclosure can be used to achieve at least some of the following advantages, at least temporarily or at least partially: a) shared use of signal lines for two signals SIG-1 and SIG-2, such as physical channels according to the UCIe standard; b) without interference with, for example, standardized UCIe communication (signal SIG-1) due to the transmission of the second signal SIG-2; c) bypassing the UCIe software stack; d) achieving secure, for example, redundant communication, such as physical redundancy, when using multiple signal lines, such as differential UCIe signal pairs; e) providing chip system-related services, such as when the second signal SIG-2 is used in addition to standard UCIe communication via the first signal SIG-1, without, for example, leaking information associated with the second signal SIG-2.
