Question

Suppose the memory cells at addresses 00 through 0D in the machine described in Appendix C contain the following bit patterns:Address Content00 20

01 04
02 21
03 01
04 40
05 12
06 51
07 12
08 B1
09 0C
0A B0
0B 06
0C C0
0D 00Assume that the machine starts with its program counter containing 00.
What bit pattern is in the program counter when the machine halts?

Answer 1

The bit pattern in the program counter when the machine halts is 03.

Step-by-step explanation:

To determine the bit pattern in the program counter when the machine halts, we need to follow the execution of the program. The machine starts with the program counter containing 00. The contents of address 00 are 2001, which means that the program counter will be set to the next instruction, which is 02. The contents of address 02 are 2103, so the program counter will be set to 03. This process continues until the machine halts.

Following the execution of the program, the final bit pattern in the program counter when the machine halts is 03.
