6502 endianness
Lecture
Little endian format makes the most sense for the 6502 because instructions that reference bytes in page 0 use only the offset into page 0 and can omit the page |
For example, Intel processors have traditionally been little-endian.
Motorola processors have always been big-endian.
Big-endian is an order in which the "big end" (the most-significant byte) is stored first.
Is arm64 big or little endian?
ARM cores support both modes, but are most commonly used in, and typically default to little-endian mode.
Most Linux distributions for ARM tend to be little-endian only.
The x86 architecture is little-endian.
What is the order of byte in 6502?
The 6502 processor expects addresses to be stored in 'little endian' order, with the least significant byte first and the most significant byte second.
If the value stored was just a number (e.g. game score, etc.)19 mar. 2004
Is x86 a little endian?
The x86 processors use little-endian byte ordering.
The least significant byte (LSB) of an integer is stored at the lowest address of the integer.
