Other Parts Discussed in Thread: TMS570LS1227

Hello,

I want to the performance of TMS570LS1227.

1,  How many DMIPS/MHz when the program is running in the flash?

2,  How many DMIPS/MHz when the program is running in the RAM?

3,  How many DMIPS/MHz when the program is running in the external DRAM(through EMIF)?

4,  How many DMIPS/MHz when the program is running in the external flash(through EMIF)?

    Hello Robin,

    You cannot effectively measure performance in such manner because you must consider the different memory waitstates and configuration effects at different frequencies.  ARM quotes a generic number of 1.66 DMIPS/MHz assuming a zero wait state memory.

    The best way for you to evaluate the performance would be to select a benchmark and perform the testing across the relevant use case conditions for your application.

    Regards,
