Problem Details CPU It will have these registers: PC, SP, IR, AC, X, Y. It will support the instructions shown on the next page of this document. It will run the user program at address 0. Instructions are fetched into the IR from memory. The operand can be fetched into a local variable. Each instruction should be executed before the next instruction is fetched. The user stack resides at the end of user memory and grows down toward address 0. The system stack resides at the end of system memory and grows down toward address 0. There is no hardware enforcement of stack size. The program ends when the End instruction is executed. The 2 processes should end at that time. The user program cannot access system memory (exits with error message)
