The emulator supports a register width of 64 bits or any greater power of two, and chunk sizes of 8, 16, 32 and 64 bits. You have to change just one #define and recompile.Juste to be sure of what we speak about. A 256 bits f-cpu use 4x64, 8x 32, 16x16, 32*8 bits words. It's not a question of using 256, 8x32,16x16,32x8 bits registers ? Thats simd instruction, otherwise it always use 64 32 16 8 bits in scalar.
