Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quantum computing, in particular, to a processor architecture and method based on dynamic overwrite instruction stream. BACKGROUND

[0002] Quantum computing puts forward high performance requirements on classical electronic control time precision, response timeliness, dynamic instruction scheduling, etc. In particular, in the scenarios of quantum error correction and adaptive feedforward control according to changes in the external environment, the processor needs to directly schedule quantum circuits for execution within the coherence time scale of the quantum bits, and flexibly and efficiently adjust the main program instruction stream according to the real-time changes in the error correction decoding results and the environmental parameters, so as to meet the needs of real-time feedback control and dynamic instruction stream adjustment.

[0003] In view of the two core requirements of quantum computing on the special-purpose processor, one is real-time monitoring and scheduling of instruction execution. The external system needs to have the tracking ability of the processor execution progress, accurately know the current program counter (PC) position, and pause or start the processor instruction execution at a specific instruction position, so as to prevent the execution of outdated instruction sequences.

[0004] The other is to dynamically modify the future instruction stream during the execution of quantum computing. The quantum error correction decoder and the environmental parameter change feedforward module dynamically generate a new instruction stream and load it into the special-purpose processor instruction memory, which covers or inserts the part of the program that has not been executed, so as to realize the dynamic reconstruction of the instruction stream.

[0005] In order to meet the above two core requirements, there are two types of technologies in the prior art. The first type is multi-path program design based on jump logic. All possible instruction paths are written into the instruction memory in advance, and different paths are executed by selecting jump instructions during running. However, in the complex quantum information processing scenario, the processor may face highly dynamic and unpredictable state changes, and the number of possible states increases exponentially with the number of quantum bits, making it difficult to enumerate all possible control paths in advance. This method not only brings a large number of redundant instructions to occupy limited instruction storage resources, but also lacks the ability to generate new instructions flexibly at runtime, making it difficult to achieve truly dynamic instruction stream modification.

[0006] The second type is the partial reconfiguration function based on FPGA. During the running of the processor, the logic of a certain region of the FPGA is reconfigured, so that the processor can dynamically switch the function hardware IP or instruction extension logic for different stages or tasks. In the microarchitecture of the processor, a new instruction implementation module is loaded through partial reconfiguration at runtime. This module acts as the execution path of the customized instruction when the processor is executed, achieving the purpose of extending or modifying the instruction set architecture (ISA).

[0007] However, the method can only reconfigure part or all of the functional IP in the FPGA, and cannot modify the instruction stream in the specific IP. The instruction stream in the reconfigured IP is also predefined and not dynamically generated as the experiment progresses, which is not suitable for real-time insertion, modification or deletion of instructions at the instruction level. At the same time, the reconfiguration process takes a long time and is not suitable for real-time control systems that are sensitive to time. In addition, the method lacks the ability to generate instructions at runtime, and existing hardware reconfiguration mechanisms rely on predefined configuration files and cannot dynamically generate new control logic or instruction streams based on real-time data or feedback generated by the experiment.

[0008] The two types of methods described above do not fully meet the two core requirements of the quantum computing dedicated processor.

[0009] The part of the background art is only the technology known to the discloser, and does not necessarily represent the prior art in the field. SUMMARY

[0015] According to some embodiments of the present application, the preset difference condition is that the difference between the target write address of the target update instruction stream and the current address is greater than or equal to 10.

[0041] Referring to Figure 1 The processor architecture 20 based on dynamic overwritten instruction stream provided by the present application can include a processor core 21, an instruction storage module 22, a state detection module 23, a dynamic instruction modification module 24 and a dynamic scheduling coordination module 25. The processor architecture 20 can be used in the application scenario of quantum computing.

[0042] The following will be described in combination with Figure 1 The execution method 1000 of the processor architecture based on dynamic overwritten instruction stream provided by the present application is described.

[0043] Referring to Figure 2 The method 1000 can include steps S100-S400.

[0044] In step S100, the current address of the current instruction stream of the processor core is acquired in real time.

[0045] According to an example embodiment, the instruction storage module 22 stores the entire instruction stream of the processor core 21, and the instruction storage module 22 at least includes a first port and a second port. The first port is used to load the main program instruction stream of the processor core 21. The second port can be used for the processor core 21 to read the instruction stream and overwrite the instruction stream by the dynamic instruction modification module.

[0046] For example, the instruction storage module 22 can be a dual-port BRAM resource inside the FPGA. The first port is an initialization loading port, used for the external processing system to load the main program instruction stream. The second port is a runtime access port, used for the processor core 21 to read the instruction stream and the dynamic instruction modification module to overwrite the instruction stream.

[0047] The second port can also be provided with two, one second port is a read port, used for the processor core 21 to read the instruction stream, and the other second port is a write port, used for the dynamic instruction modification module 24 to overwrite the instruction stream. The two second ports can be accessed simultaneously.

[0048] The processor core 21 can be a physical unit that independently executes an instruction sequence (thread). The processor core 21 can be based on a custom instruction set architecture, with a five-stage pipeline structure, to achieve efficient instruction execution and peripheral control, and meet the timing control requirements in quantum computing experiments. For example, the processor core 21 can be based on the RISC-V basic instruction set, and extend a special instruction set subset optimized for control tasks. The processor core 21 can use a five-stage pipeline structure to improve the processing efficiency and throughput capacity of the instruction stream. The internal pipeline structure does not use a cache mechanism, simplifying the execution model, and is suitable for real-time applications with high requirements for determinism and controllability.

[0049] The current instruction stream can be a dynamic instruction sequence that the processor core fetches, decodes, and executes at runtime. The current address can be the address corresponding to the current instruction stream.

[0050] For example, in step S100, the state detection module 23 can obtain the current address of the current instruction stream of the processor core in real time.

[0051] The state detection module 23 can determine the current address by obtaining the count value of the program counter of the current instruction stream.

[0052] In step S200, the target updated instruction stream of the processor core is determined according to the received quantum computing input signal.

[0053] According to an example embodiment, the quantum computing input signal can be quantum information sent by an external device for the processor core to operate.

[0054] Optionally, the quantum computing input signal can include target task data, a program count value, and a count value of a program counter of the current instruction stream.

[0055] The target task data can be target processing data for a specific quantum computing task. The program count value can be a counter value (timestamp). The count value of the program counter of the current instruction stream can be the current control program execution position (PC) of the processor core.

[0056] The target update instruction stream can be a sequence of instructions to be executed by the processor core generated according to the quantum computing input signal.

[0057] For example, in step S200, the dynamic instruction modification module 24 determines the target update instruction stream of the processor core according to the received quantum computing input signal. The dynamic instruction modification module can generate the target update instruction stream according to the quantum computing input signal and a preset signal generation rule.

[0058] For example, in a mid-circuit feedback scenario, the target task data can be the result of mid-circuit measurement (0 or 1, detected and analyzed by an external quantum state detection module). The quantum computing input signal can include the result of mid-circuit measurement 0 or 1, the counter value (timestamp), and the current control program execution position (PC). The dynamic instruction modification module 24 can generate the target update instruction stream to be executed according to the preset feedback rule according to the result of mid-circuit measurement 0 or 1. For example, the result of mid-circuit measurement is 1, and the target update instruction stream is to insert an X gate; the result of mid-circuit measurement is 0, and the target update instruction stream is to insert an I gate. The generation method of the target update instruction stream can include a lookup table and a conditional instruction template.

[0059] For another example, in a quantum error correction scenario, the target task data can be the measurement result of a syndrome in a quantum error correction code. The quantum computing input signal can include the measurement result of a syndrome in a quantum error correction code, the counter value (timestamp), and the current control program execution position (PC). The quantum computing input signal can also include error model parameters, encoding scheme information, and quantum error correction round information. The dynamic instruction modification module 24 can determine which Pauli error correction operation needs to be executed according to the syndrome, and the implementation method includes a fast decoding algorithm and a neural network inference method. The dynamic instruction modification module 24 can further combine other information in the quantum computing input signal to construct a legal target update instruction stream.

[0060] In step S300, it is determined whether the current address is less than the start address of the target update instruction stream.

[0061] According to an example embodiment, the start address of the target update instruction stream can be the start storage address of the target update instruction stream in the instruction storage module 22. The dynamic scheduling coordination module 25 can determine whether the current address is less than the start address of the target update instruction stream, so that the target update instruction stream can be written to the unexecuted instruction address of the instruction storage module.

[0062] In a case where it is judged that the current address is greater than or equal to the start address of the target update instruction stream, it is indicated that the target update instruction stream has been executed or entered into the pipeline, and at this time, the dynamic modification operation should be stopped for safety consideration.

[0063] In a case where it is judged that the current address is less than the start address of the target update instruction stream, step S400 is executed.

[0064] In step S400, the target update instruction stream is written into the target address interval, so that the processor core executes the target update instruction stream.

[0065] According to an example embodiment, the target address interval can be an address interval in which the target update instruction stream is written into the instruction storage module. The target address interval is within an instruction address of the instruction storage module that has not been executed.

[0066] For example, in step S400, the dynamic instruction modification module 24 writes the target update instruction stream into the target address interval of the instruction storage module through the second port. The processor core 21 can execute the target update instruction stream to complete the operation (such as an insertion, replacement, or deletion operation, etc.) of the target update instruction stream.

[0067] Through the above embodiment, the technical scheme of the present application can acquire the current address of the current instruction stream of the processor core in real time, determine the target update instruction stream of the processor core through the quantum computing input signal, judge whether the current address is less than the start address of the target update instruction stream, and in a case where the current address is less than the start address of the target update instruction stream, write the target update instruction stream into the target address interval, so that the processor core executes the target update instruction stream.

[0068] The processor architecture of the present application has an instruction stream dynamic modification capability. Through the dynamic instruction modification module of hardware, an instruction segment that has not been executed is generated and overwritten in real time according to an input signal when the processor core is running, which realizes online update and replacement of the main program instruction stream that cannot be completed by a traditional processor architecture, and is suitable for a control system with strong environmental dynamics. At the same time, the processor architecture has the flexibility of traditional software self-repairing code and the high performance characteristics of FPGA hardware partial reconfiguration, and has high response speed and control accuracy.

[0069] The processor architecture of the present application avoids the high overhead and low timeliness problem of partial reconfiguration, and the technical scheme of the present application does not need to reload a logic region, which improves the response speed and control accuracy of the processor architecture.

[0070] The processor architecture of the present application can enhance the processing capability of abnormal conditions and unexpected events. In the face of sudden state changes in experiments or dynamic instruction flow requirements, the processor architecture can switch execution strategies and inject target update instruction flow in real time, enhancing the self-recovery and robustness of the processor architecture.

[0071] The processor architecture of the present application can provide efficient computing support for precision experiment control and dynamic feedback systems. This architecture is particularly suitable for scenarios such as quantum experiment control and programmable triggering, and can respond to changes in experimental state at processor level precision, effectively addressing the bottleneck of insufficient control precision of general-purpose architectures.

[0072] Optionally, referring to Figure 3 , step S100 can include steps S110-S120.

[0073] In step S110, the count value of the program counter of the current instruction stream is obtained.

[0074] According to an example embodiment, the count value of the program counter can be the register value of the memory address in the instruction storage module corresponding to the current instruction stream.

[0075] For example, in step S110, the state detection module 23 obtains the count value of the program counter of the current instruction stream. The state detection module 23 can read the count value of the program counter of the current instruction stream of the processor core.

[0076] In step S120, the current address is determined according to the count value of the program counter.

[0077] According to an example embodiment, the state detection module 23 can determine the current address according to the count value of the program counter. For example, the state detection module 23 can directly take the read count value of the program counter as the current address of the current instruction stream in the BRAM.

[0078] Through the above embodiments, the technical scheme of the present application can obtain the count value of the program counter of the current instruction stream, and determine the current address through the program count value.

[0079] The processor architecture of the present application can determine the current address by monitoring the count value of the program counter of the current instruction stream in real time, so as to determine whether the initial address of the target update instruction has entered the pipeline.

[0080] Optionally, referring to Figure 4 , step S400 can include steps S410-S430.

[0081] In step S410, it is determined whether the difference between the target write address of the target update instruction stream and the current address satisfies a preset difference value condition.

[0082] According to an example embodiment, the target write address can be an instruction address of the target update instruction stream being written. The preset difference condition can be a preset difference threshold of the target write address and the current address of the target update instruction stream.

[0083] Optionally, the preset difference condition can be that the difference between the target write address and the current address of the target update instruction stream is greater than or equal to 10.

[0084] For example, in step S410, the dynamic scheduling coordination module 25 determines whether the difference between the target write address and the current address of the target update instruction stream satisfies the preset difference condition. The dynamic instruction modification module 24 needs a certain time to write the instruction stream to the instruction storage module 22, and the dynamic scheduling coordination module 25 can determine whether to suspend the work of the processor core 21 by the writing of the target update instruction stream, so as to avoid that the processor core 21 reads the un-updated instruction stream.

[0085] If it is determined that the difference between the target write address and the current address of the target update instruction stream satisfies the preset difference condition, step S420 is performed.

[0086] In step S420, the target update instruction stream is directly written to the target address interval, so that the processor core executes the target update instruction stream.

[0087] According to an example embodiment, if it is determined that the difference between the target write address and the current address of the target update instruction stream satisfies the preset difference condition, it indicates that the address distance between the target write address and the current address is far, and the dynamic instruction modification module 24 can directly write the target update instruction stream to the target address interval of the instruction storage module 22 through the second port.

[0088] If it is determined that the difference between the target write address and the current address of the target update instruction stream does not satisfy the preset difference condition, step S430 is performed.

[0089] In step S430, after suspending the reading of the instruction stream by the processor core, the target update instruction stream is written to the target address interval, so that the processor core executes the target update instruction stream.

[0090] According to an example embodiment, if it is determined that the difference between the target write address and the current address of the target update instruction stream does not satisfy the preset difference condition, it indicates that the address distance between the target write address and the current address is close, and the dynamic instruction modification module 24 writes the target update instruction stream to the target address interval of the instruction storage module 22 through the second port after suspending the work of the processor core 21.

[0091] Through the above embodiments, the technical scheme of the present application can determine whether the work of the processor core needs to be suspended by judging whether the difference between the current address and the target write address of the target update instruction stream meets the preset difference condition, and in the case that the difference between the current address and the target write address of the target update instruction stream meets the preset difference condition, the program behavior can be quickly updated without suspending the entire processor architecture, thereby significantly improving the response speed and control accuracy of the processor architecture.

[0092] According to another aspect of the present application, the present application further provides a non-volatile computer readable storage medium having a computer program stored thereon, the computer program being executable by a processor to implement the execution method of the processor architecture based on the dynamic overwritten instruction stream as described above.
