Suppose that the following instruction is found at the given address/location in memory: Address 05 06 Instruction LDA 20 Data 15 20 The instruction LDA 20 residing at address 05 loads the contents of memory location 20, which is 15, into the Accumulator (A). Draw the diagram showing the contents of the CPU (PC, IR, A), MAR, Memory, and MDR, after each of the 5 steps of the fetch-execute cycle is executed. Fill in the table below with the contents of the PC, MAR, MDR, IR, and A as each of the 5 steps of the fetch-execute cycle is performed for that instruction. If the content of the register is unknown, write a question mark?". MAR Main Memory (RAM) CPU PC IR MDR PC MAR MDR IR (1) PC MAR (2) MDR IR (3) IR (address] MAR (4) MDR A (5) PC+1 PC |||||
