Consider the following program program written in 6502 assembler language. ; load the accumulator with the value e LDA #0 loopl: ; compare the accumulator with the value 5 CMP #5 BEQ outsidel ; if the comparison was equal jump to outsidel STA $D020 ; store the value in the accumulator somewhere CLC ; clear the carry flag ; add 1 to the accumulator ADC #1 JMP loop1 ; jump to loop1 outsidel: ; return from subroutine RTS How many times will the loop in this code run? (1.e. how many times does the sTA instruction get executed?) Assuming that: • this is running on a processor with a 5 stage pipeline • each stage takes 1 cycle • instructions that change the flow of code (BEQ, JMP, RTS) empty the pipeline after the instruction has run • the pipeline starts empty. How many cycles will this program take to run?

Assembly language 

Consider the following program program written in 6502 assembler language. ; load the accumulator with the value 0 LDA #0 loop1: ; compare the accumulator with the value 5 BEQ outsidel ; if the comparison was equal jump to outsidel CMP #5 STA $D020 ; store the value in the accumulator somewhere CLC ; clear the carry flag ADC #1 ; add 1 to the accumulator JMP loop1 ; jump to loop1 outsidel: RTS ; return from subroutine How many times will the loop in this code run? (i.e. how many times does the sTA İnstruction get executed?) Assuming that: • this is running on a processor with a 5 stage pipeline • each stage takes 1 cycle • instructions that change the flow of code (BEQ, JMP, RTS) empty the pipeline after the instruction has run • the pipeline starts empty. How many cycles will this program take to run?
