Assembly Instruction Set

Charlie Lee

Hi,

I read the CPU Instruction Set document (spru430e). There is an acronym "CYC" which I can't find any explanation to it. Can someone explain to me?

Thanks!

CYC are CPU clock cycles. The numbers are best case and assume the instruction/data is in zero-wait RAM.

So, assume running at 150Mhz and an instruction with CYC=1. It would take approximately 6.67ns to execute, correct?

Yes, that is correct.
