datawidth
Datawidth is the number of bits used to represent a unit of data in a computer system for a given operation or transfer. It is a key characteristic of data paths, registers, memory interfaces, and word sizes, and it directly influences how much data can be processed or moved per cycle. Datawidth is distinct from address width, which determines how many memory locations can be addressed.
In hardware, datawidth often aligns with the processor’s natural word size and the width of its arithmetic
Memory and I/O performance are heavily influenced by datawidth. A wider data bus can transfer more bits
Some devices support multiple data widths or operate in mixed-width modes, and endianness or data encoding
