WebJan 6, 2024 · Advanced High-performance Bus (sometimes known as AHB) is an acronym. It is a single-channel bus that is also a shared bus. It has one address channel, one read data channel, and one write data channel, all of which are connected. A simple transaction with AHB requires only two bus cycles, one for the address phase and the other for the … WebJun 3, 2014 · Word invariant meaning word reads give the same answer. A byte read of address zero in little endian mode of the same address would be 0x78 and big endian byte read (ldrb) would be 0x12.

In computing, endianness is the order or sequence of bytes of a word of digital data in computer memory. Endianness is primarily expressed as big-endian (BE) or little-endian (LE). A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest. A little-endian system, in contrast, stores the least-significant byte at the smallest address. Bi-endianness is a feature supported by numerous computer architecture… WebMay 6, 2024 · Modern CPUs have internal busses up to 64 bytes wide (e.g. between L2 and L1d cache in Skylake, and between SIMD load/store units and L1d cache in Skylake-avx512 and later Intel CPUs).

"byte invariant" endianness was only added as an option to the AMBA 5 AHB spec, so the tables in the AMBA 3 AHB-lite spec must be "word-invariant". As to why the big-endian table in the AMBA 5 AHB spec is different, it's simply because the AMBA 5 spec is describing how …
