structural hazards

Question

Can we completely remove structural hazards..if we have separate intruction memory and data memory?

Answer 1

Yes, in classic pipeline questions but not in actual pipeline. Because cache memory (Instruction Cahe + Data cache) is not the only structure in pipeline. There can be many functional units which are shared by instructions and ideally there should be enough of them to ensure no wait in a pipeline.

Comments

But this is hazard to read at same time?

so what in same cycle we use memory for diffrent purpose. intruction fetch used for Instrution and Oprand  fetch for Data.

Make Two partition of memory [WE assume it like that ] intruction  memeory and data memory.

Yes..
