Course:(( computer architecture)) Q1: A 64K x 24 memory, shown below, is used to store instructions and data for a 24-bit computer architecture, which is an advanced version of the Basic Computer discussed in class. The first instruction is stored at memory address location 4003h. Fill in the table below with the values for PC, MAR, IR, and ACX? Initial values mean the values of the registers prior to fetching the first instruction from memory. The instruction consists of an 8-bit Opcode and a 16-bit address. Opcode 30h : load ACX from memory Opcode 33h : store AC to memory, Opcode 50h: add to ACX operand from memory Opcode 3Ah : OR to ACX Opcode 3Fh: AND to ACX (All numbers are in hexadecimal)
