hai,

what is the time taken for executing a single instruction.

i mean what is the time for one machine cycle, if processor frequency is 48MHz.

Hi anuradha,

the time for one machine cycle is not the same for all instructions it also depends on where you are executing the instruction from flash or SRAM.

It depends on the instruction itself - some execute in one clock cycle, some take longer than that.

i mean what is the time for one machine cycle, if processor frequency is 48MHz.

1/48MHz = 20.83333333 ns

BTW, there was a discussion some time ago about this topic:

I can't find detailed information about instruction cycle times

Get this:
