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 ...

LEB128 or Little Endian Base 128 is a variable-length code compression used to store arbitrarily large integers in a small number of bytes. LEB128 is used in the DWARF debug file format [ 1 ] [ 2 ] and the WebAssembly binary encoding for all integer literals.
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.
Hexspeak is a novelty form of variant English spelling using the hexadecimal digits. Created by programmers as memorable magic numbers, hexspeak words can serve as a clear and unique identifier with which to mark memory or data.
An ordering problem that is easy to envision occurs when the data word is transferred byte-by-byte between a big-endian system and a little-endian system and the Fletcher-32 checksum is computed. If blocks are extracted from the data word in memory by a simple read of a 16-bit unsigned integer, then the values of the blocks will be different in ...
Base-128 compression is known by many names – VB (Variable Byte), VByte, Varint, VInt, EncInt etc. [1] A variable-length quantity (VLQ) was defined for use in the standard MIDI file format [2] to save additional space for a resource-constrained system, and is also used in the later Extensible Music Format (XMF).
Python 3.3 switched internal storage to use one of ISO-8859-1, UCS-2, or UTF-32 depending on the largest code point in the string. [31] Python 3.12 drops some functionality (for CPython extensions) to make it easier to migrate to UTF-8 for all strings. [32] Java originally used UCS-2, and added UTF-16 supplementary character support in J2SE 5.0.
