Is My Calculation of PC, AR, DR, AC, and IR Using the STA Instruction Correct?

Click For Summary
SUMMARY

The discussion centers on the calculation of the Program Counter (PC), Address Register (AR), Data Register (DR), Accumulator (AC), and Instruction Register (IR) using the STA instruction in a computer architecture context. The user provided initial values: I=0, PC=100, AC=ABCD, and memory content at address 055 as 7777. The calculated values are PC=101, AR=055, DR=ABCD, AC=ABCD, and IR=3055, which are confirmed as correct based on the assumption that memory location 100 contains the value 3055.

PREREQUISITES
  • Understanding of computer architecture concepts, specifically the STA instruction.
  • Familiarity with the roles of Program Counter (PC), Address Register (AR), Data Register (DR), Accumulator (AC), and Instruction Register (IR).
  • Knowledge of memory addressing and data storage in computer systems.
  • Basic proficiency in interpreting assembly language instructions.
NEXT STEPS
  • Study the operation of the STA instruction in detail.
  • Learn about the implications of memory addressing modes in computer architecture.
  • Research how the Program Counter (PC) increments during instruction execution.
  • Explore the role of the Instruction Register (IR) in the fetch-decode-execute cycle.
USEFUL FOR

Students and professionals in computer science, particularly those focusing on computer architecture, assembly language programming, and instruction execution processes.

I have an issue with my computer architecture problem.

Computer has intial I=0, PC=100, AC=ABCD, Address 055. The content of memory location (055) is 7777. I have to find PC, AR, DR, AC, and IR from that information using the STA instruction.

The STA instruction is M[AR] <-AC

I calculated the following values and believe it is correct...

PC=101;
AR=055;
DR=ABCD;
AC=ABCD;
IR=3055;

Can anyone tell me if this is correct?

This looks correct, assuming the memory location 100 contains the value 3055.
