Show the contents in hexadecimal of registers PC, AR, DR, IR, and SC of thebasic computer when an ISZ indirect instruction is fetched from memory andexecuted. The initial content of PC is 7FF. The content of memory at address7FF is EA9F. The content of memory at address A9F is 0C35. The content ofmemory at address C35 is FFFF. Give the answer in a table with five columns,one for each register and a row for each timing signal. Show the contents of theregisters after the positive transition of each clock pulse.170 CHAPTER FIVE Basic Computer Organization and Design

The content of AC in the basic computer is hexadecimal A937 and the initialvalue of E is 1. Determine the contents of AC, E, PC, AR, and IR in hexadecimalafter the execution of the CLA instruction. Repeat 11 more times, starting fromeach one of the register-reference instructions. The initial value of PC is hexa-decimal 021

Consider the instructions in the given figure and find the contents of the CPU registers - PC, MAR, MDR, IR, R1 and R2.

Write assembly language insuuctions to perform each of the following tasks:i. Set register CX equal to zero (0).ii. Save the content of the memory location pointed by the.register BX in registerAX.iii. Test the contents of register AX and yariable A.iv. Branch to the label TEST if the content of register AX is greater than or equal tothe content of variable A.v. Add one (01) to register CX.vi. Compare the content of register CX with the value ten (10). Label the instructionas TEST.vii. Branch to the label OUT if the content of register CX is equal to ten (10).
