A method and medium for a computer readable input area. The input area is created by a computer program on a display capable of receiving touch-screen input. The computer on which the input area in used is at least a 32-bit system. The input area may contain a keyboard which is an image map. External programming may selectively access the input area through a dynamic link library. The input area has no task bar and may not be minimized, maximized, or deleted. Therefore, the input area becomes an integral component and provides the user with a constant and reliable method of inputting information into the computer program.

A system and method for detecting malware on a mobile platform in a mobile network. The system and method verifies that an executable is malware-free by computing the checksum of the executable and comparing that checksum with a checksum obtained from a malware-free copy of the executable. The checksum is a sum of all 32-bit values in a code section and an import section of said executable, a byte sequence at an entry point in said executable, a size descriptor of an import table, a size descriptor of said import section, a cyclic redundancy check of said executable, or a combination thereof.

An implantable neural stimulation system, such as an auditory Fully Implantable System (FIS), includes: (1) an implanted device capable of providing desired tissue or nerve stimulation; and (2) a remote control unit that provides a mechanism for readily controlling the implant device, i.e., for selectively adjusting certain stimulation parameters associated with the tissue stimulation of the implanted device. The remote control unit uses a first signal path to send signals to the implant device, and a second signal path to receive signals from the implant device. The combination of these two signal paths provides a full-duplex channel between the remote control unit and the implant device through which air appropriate control and status signals may be sent and received. In one embodiment, the first signal path comprises an audio signal path through which audio control signals, e.g., a tone sequence or a 32-bit word FSK modulated between 300 and 1200 Hz, are sent; and the second signal path comprises a RF signal path through which a BPSK, QPSK or FM modulated RF signal is received. The full-duplex channel allows operation of the remote control unit, i.e., allows signals to be successfully sent to and received from the implant device, from as far away as 45-60 cm from the implant device.

A processor has multiple operating modes, such as the long/compatibility mode, the long/64-bit mode and the legacy modes of the x86-64 microprocessor. Different software entities execute in different ones of these operating modes. A switching routine is implemented to switch from one operating mode to another and to transfer control from one software entity to another. The software entities may be, for example, a host operating system and a virtual machine monitor. Thus, for example, a virtual computer system may comprise a 64-bit host operating system and a 32-bit virtual machine monitor, executing on an x86-64 microprocessor in long mode and legacy mode, respectively, with the virtual machine monitor supporting an x86 virtual machine. The switching routine may be implemented partially or completely in an identity-mapped memory page. Execution of the switching routine may be initiated by a driver that is installed in the host operating system of a virtual computer system.

Systems and methods are provided for sending information in a first protocol over a network that supports a second protocol. A tunnel is used to provide a roaming mobile node with IPv6 packet data over an IPv4 core network. When the mobile node is handed off while roaming, the same IP address is provided to the mobile node and the IPv6 packet data is again tunneled over the IPv4 core network. Certain embodiments allow an IPv4 core network to support a mobile node that uses Simple IPv6 or MIPv6 addressing. This system and method can be applicable to situations where the mobile node uses addressing greater than 32 bits, while the core network supports 32 bit addressing.

A memory system provides data error detection and correction and address error detection. A Single-byte Error-Correcting/Double-byte Error-Detecting (SbEC/DbED) code with the byte being a 4-bit nibble is used to detect up to 8-bit errors and correct data errors of 4 bits or less. Rather than generating address parity, which is poor at detecting even numbers of errors, a cyclical-redundancy-check (CRC) code generates address check bits. A 32-bit address is compressed to just 4 address check bits using the CRC code. The 4 address check bits are merged (XOR'ed) with two 4-bit nibbles of the data SbEC/DbED code to generate a merged ECC codeword that is stored in memory. An address error causes a 2-nibble mis-match due to the redundant merging of the 4 address check bits with 2 nibbles of data correction code. The CRC code is ideal for detecting even numbers of errors common with multiplexed-address DRAMs.

Pseudo-random numbers (PRNs) generated by a PRN generator are mapped to predefined number ranges or target ranges. The target range may be smaller or larger than the range of the PRN generator. Mapping to a smaller target range may include generating PRNs (e.g., integers) from a particular bit-input stream (e.g., 32-bit) having a uniform distribution across the range of numbers; selecting an optimal subset of the generated PRNs to map; and mapping the selected PRNs to a corresponding number in a target range such that the mapped numbers are uniformly distributed across the target range. Mapping to a larger target range may include generating uniformly distributed PRNs; applying a generation function to the PRNs to generate uniformly distributed packed numbers; and applying a mapping function to map selected packed numbers to the target range such that the mapped numbers are uniformly distributed.

A processor element, structured to execute a 32-bit fixed length instruction set architecture, is backward compatible with a 16-bit fixed length instruction set architecture by translating each of the 16-bit instructions into a sequence of one or more 32-bit instructions. Switching between 16-bit instruction execution and 32-bit instruction execution is accomplished by branch instructions that employ a least significant bit position of the address of the target of the branch to identify whether the target instruction is a 16-bit instruction or a 32-bit instruction.

Apparatus and methods for combining metadata with video into a video stream using a 32-bit aligned payload, that is computer storage efficient and human discernable. The metadata is stored in a track in a self-describing structure. Metadata track may be decoded using an identifier reference table that is substantially smaller than typical fourCC identifier tables. The combined metadata/video stream is compatible with a standard video stream convention and may be played using conventional media player applications that reads media files compliant with MP4/MOV container format. The proposed format may enable decoding of metadata during streaming, partitioning of combined video stream without loss of metadata. The proposed format and/or metadata protocol provides for temporal synchronization of metadata with video frames.

For a processor having instruction codes of two instruction lengths (16 bits and 32 bits), methods of locating the instruction codes are limited to two types: (1) two 16-bit instruction codes are stored within 32-bit word boundaries, and (2) a single 32-bit instruction code is stored intactly within the 32-bit word boundaries. A branch destination address is specified only on the 32-bit word boundary. The MSB of each instruction code serves as a 1-bit instruction length identifier for controlling the execution sequence of the instruction codes. This provides two transfer paths from an instruction fetch portion to an instruction decode portion within the processor, achieving reduction in code side and in the amount of hardware and, accordingly, the increase in operating speed.

Methods, apparatus and systems for the display, on a remote node, of a three-dimensional (3D) image rendered on a host system in a first image format are described. In general, the 3D image is transformed into a second image format that is compressed (i.e., uses fewer data bits per pixel) relative to the first image format, (optionally) scaled to a screen size of remote node, and subsequently transferred to remote node for display. In instances, the transformation of the image from the first image format to the second image format and the optional scaling of the image to the screen size of remote node may be done in a graphics processing unit (GPU) on the host system. As an example, the first image format may be an RGB-based format, such as RGBA (32-bits per pixel) or standard RGB (24-bits per pixel) and the second image format may be a YUV-based format, such as YV12 (12-bits per pixel).

A system and method for encoding a sequence of 32 bit digital data words into a sequence of 33 or more bit codewords having constraints of (d=0, G=9/I=9) for recording upon a magnetic medium within a magnetic recording channel are disclosed. The method includes dividing each 32 bit digital data word into three 8-bit bytes and another 8-bit byte, expanding the another 8-bit byte into a 9-bit word, dividing the 9-bit word into three 3-bit subparts, forming three 11-bit intermediate blocks, each comprising one of the three 3-bit subparts and one of the three 8-bit bytes, encoding each of the three 11-bit intermediate blocks to generate three 11-bit encoded words, and forming each codeword from a set of the three 11 -bit encoded words. The set of the three 11-bit encoded words satisfies a predetermined minimum zero run length (d) constraint, a predetermined maximum zero run length (G) constraint, and a predetermined maximum interleave zero run length (I) coding constraint.

A memory system provides data error detection and correction and address error detection. A cyclical-redundancy-check (CRC) code generates address check bits. A 32-bit address is compressed to 6 address check bits using the CRC code. The 6 address check bits are concatenated with 64 data bits and 2 flag bits to generate a 72-bit check word. The 72-bit check word is input to an error-correction code (ECC) generator that generates 12 check bits that are stored in memory with the 64 data bits. A 76-bit memory module can store the 64 data and 12 check bits. Nibble errors can be corrected, and all nibble+1 bit errors can be detected. Also, a 6-bit error in a sequence of bits can be detected. This allows all errors in the 6-bit CRC of the address to be detected. The CRC code and ECC are ideal for detecting double-bit errors common with multiplexed-address DRAMs.
