Any method to verify 8051-1T is really running at 1 ck/instr

8051 1t

Does anyone know any quick and easy method to verify a 8051-1T is really running at 1T performance, i.e. 1 clock per instruction cycle?

I am going to purchase a 8051-1T soft core and need to plan how to "prove" the performance of it. Any input would be highly appreciated.

Thanks,
Mark

Write code that will set a pin "H" or "L" and then execute 999 998 dummy instructions then set the same pin "L" or "H - all together 1 000 000 instructions ..
Using a Period Meter measure for how long pin is SET (H or L) ..
