To find the processor instruction cycle of 8051

 

To find processor instruction cycle (Machine cycle) of 8051 microcontroller

Clock frequency of 8051 is 11.059MHz.

12 machine cycle makes 1 clock cycle

so,

12 * machine cycle = 11.059MHz.

Machine cycle = 11.059Mhz/12 = 921583 Hz.

Instruction cycle = 1/921583 = 1.085 microseconds
