Answer:

Download the gif image file from this link. https://drive.google.com/open?...

In this, I have shown how you can see the " for loop " conversion into assembly language by C51 compiler of Keil software.

1 FOR LOOP iteration is made up of following instructions in assembly language

INC = 1 MC

CJNE = 2 MC

MOV = 1 MC

XRL = 1 MC

ORL =1 MC

JNZ = 2 MC

hence it takes 8 MC for the execution of 1 "for loop"

Note: 1MC = 1 machine cycle

for execution of 1 " for loop" iteration it takes approximately 8 machine cycles and you know that if my crystal oscillation frequency is 11.0592 MHz then 1mc = 1.085 us. so for execution of 1 iteration of for loop takes approximately 8 x 1.085 us = 8.68 us. therefor for 1 ms it will take (1ms / 8.68 us) = 115 iterations since outer "for loop" also takes some machine cycles to execute I took the approximate value as 113 iterations.
