  2. Endianness - Wikipedia

    en.wikipedia.org/wiki/Endianness

    An example of the former is the binary XLS file format that is portable between Windows and Mac systems and always little-endian, requiring the Mac application to swap the bytes on load and save when running on a big-endian Motorola 68K or PowerPC processor.

  3. Comparison of data-serialization formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_data...

    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. 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.

  6. SREC (file format) - Wikipedia

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

    The address bytes are arranged in big-endian format. Data - a sequence of 2 n hex digits, for n bytes of the data. For S1/S2/S3 records, a maximum of 32 bytes per record is typical since it will fit on an 80 character wide terminal screen, though 16 bytes would be easier to visually decode each byte at a specific address.

  7. Double-precision floating-point format - Wikipedia

    en.wikipedia.org/wiki/Double-precision_floating...

    There are ARM processors that have mixed-endian floating-point representation for double-precision numbers: each of the two 32-bit words is stored as little-endian, but the most significant word is stored first. VAX floating point stores little-endian 16-bit words in big-endian order

  8. Universally unique identifier - Wikipedia

    en.wikipedia.org/wiki/Universally_unique_identifier

    When saving UUIDs to binary format, they are sequentially encoded in big-endian. For example, 00112233-4455-6677-8899-aabbccddeeff is encoded as the bytes 00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff .

  9. PDP-11 architecture - Wikipedia

    en.wikipedia.org/wiki/PDP-11_architecture

    Double words are used by the MUL, DIV, and ASHC instructions. Other 32-bit data are supported as extensions to the basic architecture: floating point in the FPU Instruction Set or long data in the Commercial Instruction Set are stored in more than one format, including an unusual middle-endian format [2] [3] sometimes referred to as "PDP-endian."
