15 years agoThank you for your answer and the explanation of the ALT_LOAD_SECTION behavior.
--- Quote Start --- Putting code (and data) in tightly coupled memory areas gives the same access times as if the data were resident in the instruction/data cache. --- Quote End --- This was already clear to me. I simply wondered if I can expect any significative speed improvement in placing frequently accessed code/data in a dedicated tightly coupled memory. Note that I already use a Nios II/f code with cache: anyway I want very fast execution of this function, so I'd like to exclude cache delays due to loading/flushing. I add one more issue to this thread: I tried to place in tc_code section a more complex function, namely the actual function I need to speed up. Now the processor gets stuck whenever this funciton is called! The previous call to testcall() is still present and it has no problem. Why? Regards Cris
