1. text provides an example of the execution of a simple MARIE program. For this problem, you are to complete a similar example for a different program. In particular, for the MARIE program given below, you are to complete the equivalent of Figure, but for the program below. You do not need to show how the "Halt" instruction is executed. Specify values in PC, IR, MAR, MBR, and AC in hexadecimal. A template for your answer is provided as a Microsoft Word file that is included with this assignment on Scholar. You are to incorporate your answer for this problem into your submission for the homework assignment so that you submit only one PDF file for the entire assignment.
The program is as follows. Note that this table is the equivalent of Table, only for a different program.
