Honored Contributorhello;
i understand that to write a delay loop using Nios instruction set, i need to know how many clock cycles each instruction inside the loop takes...I am using the NiosII /e...anyone has the timing for all the instructions?
Honored ContributorThey are in the documentation: for the /e version they are all 6, + the duration of any Avalon MM cycle.
The /f does most ALU instructions in 1 clock, branches being 1, 2 or 4 (predicted not taken, predicted taken, mispredicted), results of non-ALU (and slow ALU) instructions are unusable in the next two instructions as they miss the 'fast path' and have to go via the register file.
