Hi,
I have one question.
Does C66x devices have "Sync" instruction.
I don't know well regarding DSP instruction. Some risc processor has "Sync" instruction. "Sync" instruction guarantees the order of memory access.
Does C66x have similar instruction?
My customer would like to evaluate C66x performance. So customer would like to measure the execution time of the functions. Customer thinks to use
the below sequence.
* Read the timer value ---> * Execute the function ---> * Read the timer value
But, if the order of the function instruction and timer read instruction are changed, it is impossible exactly to measure the execution time of the function.
So customer hopes to guarantee the order of instruction never changed.
Does someone have the answer of this question?
I appreciate your quick reply.
Best regards,
Michi
