    BER: variable-length big-endian binary representation (up to 2 2 1024 bits); PER Unaligned: a fixed number of bits if the integer type has a finite range; a variable number of bits otherwise; PER Aligned: a fixed number of bits if the integer type has a finite range and the size of the range is less than 65536; a variable number of octets ...

  4. Endianness - Wikipedia

    en.wikipedia.org/wiki/Endianness

    For instance, the 32-bit desktop-oriented PowerPC processors in little-endian mode act as little-endian from the point of view of the executing programs, but they require the motherboard to perform a 64-bit swap across all 8 byte lanes to ensure that the little-endian view of things will apply to I/O devices. In the absence of this unusual ...

    The difference between big- and little-endian is the order of the four bytes of the integer being stored. The first diagram shows a computer using little-endian. This starts the storing of the integer with the least-significant byte, 0x0D, at address a, and ends with the most-significant byte, 0x0A, at address a + 3.

  6. Comparison of instruction set architectures - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_instruction...

    An architecture may use "big" or "little" endianness, or both, or be configurable to use either. Little-endian processors order bytes in memory with the least significant byte of a multi-byte value in the lowest-numbered memory location. Big-endian architectures instead arrange bytes with the most significant byte at the lowest-numbered address.

  7. Byte order mark - Wikipedia

    en.wikipedia.org/wiki/Byte_order_mark

    The BOM for little-endian UTF-32 is the same pattern as a little-endian UTF-16 BOM followed by a UTF-16 NUL character, an unusual example of the BOM being the same pattern in two different encodings. Programmers using the BOM to identify the encoding will have to decide whether UTF-32 or UTF-16 with a NUL first character is more likely.

  8. UTF-16 - Wikipedia

    en.wikipedia.org/wiki/UTF-16

    The Joliet file system, used in CD-ROM media, encodes file names using UCS-2BE (up to sixty-four Unicode characters per file name). Python version 2.0 officially only used UCS-2 internally, but the UTF-8 decoder to "Unicode" produced correct UTF-16. There was also the ability to compile Python so that it used UTF-32 internally, this was ...

  9. SREC (file format) - Wikipedia

    en.wikipedia.org/wiki/SREC_(file_format)

    If a SREC file is only used to program a memory device and the execution location is ignored, then an address of zero could be used. S8: Start Address (Termination) 24-bit Address This record contains the starting execution location at a 24-bit address. [4] [5] This is used to terminate a series of S2 records. If a SREC file is only used to ...
