Question
(1 point) A throughout the lifetime of an instance of a procedure. (1 point) A machine-level op-code to be executed and whose output is the bus enables, multiplexer controls, clocks, and signal that control the processor. 1. points to a place on the stack and can change 2. control unit runs a program whose input is the of instruction 3. (1 point) Pipelining is a technique in for improving the execution. 4. (1 point) A 1 address instruction has a register, called the to hold one operand and the result. (1 point) is a load/store RISC ISA that has 32 general purpose registers. 6. (10 points) A processor executes an instruction in the following four stages. The time required 320 ps 280 ps 350 ps by each stage in picoseconds (1,000 ps 1 ns) is given for each stage. IF Instruction fetch OF Operand fetch OE Execute oS Operand store (writeback) 220 ps a. (5 points) What is the time taken to fully execute an instruction assuming that this structure is pipelined in four stages and that there is an additional 10 ps per stage due to the pipeli latches? (5 points) Suppose that 20% of instructions are branch instructions that are taken and cause a 2- cycle penalty, what is the effective instruction execute time? b.Explanation / Answer
1) An activation record points to a place on the stack and can change throughout the lifetime of an instance of a procedure.
2) A microprogrammed control unit runs a program whose input is the machine-level op-code to be executed and whose output is the bus enables, multiplexer controls, clocks, and signal that control the processor.
3) pipelining is a technique of improving the rate of instruction execution.
4) A 1 address instruction has a register, called the accumulator register to hold one operand and the result
