WebThe EMIF is inherently BE8, or byte invariant big endian. This device is BE32, or word invariant big endian. There is no difference when interfacing to RAM or using an 8-bit wide data bus. However, there is an impact when reading from external ROMs or interfacing to hardware registers with a 16-bit wide data bus. WebThe differences between handling Word-Invariant, or BE-32, and Byte-Invariant, or BE-8, data buses are: In a BE-32, Word-Invariant, system, the representation of a 32-bit Word access is the same between a BE-32 access and a LE access to the same word address. However, the representation of the byte (and half-word) accesses on the bus is different.

"WebMay 6, 2024 · Modern CPUs typically read all 4 bytes at once, from cache or a wide-enough external data bus. When they read a whole cache line, there is a related concept of "critical word first", i.e. stream data from memory starting with the 8-byte chunk that includes the data you're actually waiting for (the demand load that missed in cache), so the load can … " - Byte-invariant
