IP behind AvaloneMM Pipeline Bridge- Latency

Hi,

I am not sure if this is going to be helpful.

According to my old experience, the avalon bridge only operates in byte addressing mode(data bus itself can be variable). Thus you need to discard some LSBs of address as follows:

avalon datawidth bridge datawidth discard address bits

32 ........................32................... 2 LSB bits

32 ....................... 16................... 1 LSB bit

32 ........................8....................... none

Nios aligns addresses from byte to byte. Thus I expect the address to move from 0 to 1 to read two bytes across the bridge if your avalon datawidth is 16.
