WebAug 7, 2013 · Since some ARMs have BE32 (word invariant) and the newer arms BE8 (byte invariant) you would have to do even more work to try to make something generic that also tries to compensate for little intel, little arm, BE32 arm and BE8 arm. Xscale tends to run big endian natively but can be run as little endian to reduce the headaches.

WebThe AXI protocol supports the following mechanisms: • variable-length bursts, from 1 to 16 data transfers per burst • bursts with a transfer size of 8-1024 bits • wrapping, …
WebNov 6, 2024 · Conceptually, the ByteBuffer class is a byte array wrapped inside an object. It provides lots of convenient methods to facilitate reading or writing operations from/to underlying data. And, these methods are highly dependent on the indices maintained. ...

AXI uses a byte-invariant endian scheme so the receiving master will know which bits to grab from the 32bit data bus during a 16bit read.
