Question

True/False Semaphores and Murexes are ways to control what threads are allowed to run How many docks does the code below take to run? ;start here L.DR.R1,[R2] ORRS R1, #0 times 22 STO R1, (0 times 40004020) ;end here How many clocks does the code below take to run? ;start her MOV R1, #22 MOVG R2, #2 jump STO R3, (0 times 40008080) SUBs R1, R1, R2 BGE jump loop ADDS R1, R2 BNE loop exit; end here Choose the most accurate way of measuring execution time in your code. a. Use the PWM to output a beep b. Use a print for coat to output number in an internal counter c. Toggle a GPIO and measure with an oscilloscope or logic analyzer b. Use the PWM to output a beep c. Use a print f or cost to output number in an internal counter
