K70 DSP benchmark test

poul-erikhansen — Tue, 22 Jul 2014 14:01:23 GMT

I have made the following benchmark test on a TWR-K70F120M board.

I have used the ARM CMSIS DSP library.

I have used the IAR Embedded Workbench 7.20.

Used if you can Poul-Erik.

freescale TWR-MK70F120M: ARM cortex M4 120 MHz

Hi Poul,

I am working on ARM Cortex-M4 and was looking for a FPU benchmark test. I found your test and downloaded it. Thanks for putting it on this link.

When I tried to compile, I found that the functions _time_get(), _time_diff(), the structure type TIME_STRUCT are not available in the library files which you have included (math.h/arm_math.h). Where are they located? Are they customized functions written by you?

Also, have you compared the figures which you have shown here with any reference values?

Please clarify.

Thanks,

Best regards,
Rama

This is a bit late but the TIME_STRUCT is actually part of the MQX RTOS.
It is used as an object tied to the system 32-bit clock iirc.
