An apparatus for receiving and storing an incoming sequence and for forwarding the bytes of the incoming sequence as an outgoing sequence in a different byte order includes a cache memory and a main memory for storing bytes of the incoming sequence until they can be forwarded as bytes of the outgoing sequence. A control circuit selectively burst mode writes sequences of incoming bytes that need be stored for a relatively long time to blocks of sequential addresses of the main memory, writes individual bytes of the incoming sequence that need be stored for a relatively short time to selected addresses of the cache memory, and reads bytes out of the cache memory and the main memory when needed to form the outgoing sequence.

Methods, software / firmware, and apparatus to support use of software running on platform hardware employing different endianness. In one embodiment, an endian byte order shim is implemented in a firmware stack to facilitate the use of software running on a computer platform having a processor employing an endianness that is different from the endianness native to the software. In response to software calls into the firmware, the endian byte order shim converts the endian byte order of the call arguments, as necessary, and passes the converted arguments to the firmware. Similarly, return arguments generated via the firmware (and / or platform hardware) are converted back to the endian byte order native to the software prior to being returned to the software.

Method and system for supporting multiple byte order formats, separately or simultaneously, are provided and described. In one embodiment, a page attribute table (PAT), which is programmable, is utilized to indicate byte order format. In another embodiment, a memory type range register (MTRR), which is programmable, is utilized to indicate byte order format.

The invention relates to a method and device for realizing vehicle software configuration coding based on Excel, and establishes a basic database of vehicle software configuration coding; when calculating codes, input software configuration options in an Excel table; use the MATCH function as input for each software The configuration option matches the row number of the binary code in the basic database, and uses the BIN2HEX function to convert the matched binary code into a hexadecimal code byte by byte; use the CONCATENATE function to merge the obtained hexadecimal codes in byte order Become a vehicle code and display it. When reversely analyzing the code, enter the vehicle code in the input box; use the MID function to extract the hexadecimal code of each byte of the vehicle code; use the HEX2BIN function to extract the hexadecimal code of each byte of the vehicle code The base code is converted into a binary code; use the MID function to extract the binary code of each software configuration variable; use the MATCH function to find the line number of the software configuration option corresponding to the binary code in the basic database, and display it.
