Assume a RISC processor takes two microseconds to execute each instruction and an I/O device can wait at most 1 millisecond before its interrupt is serviced. What is the maximum number of instructions that can be executed with interrupts disabled?
The memory hierarchy contains a single cache with a miss rate of 2% that holds both instructions and data. The miss penalty to access main memory is 100 cycles. 15% of the instructions are jumps, 20% are stores, 20% are loads (30% have vales used in the next instruction), 10% are branches (taken 20% of the time) and 35% are ALU instructions. Jumps and branches are determined in the ID stage.
(a) What is the base CPI?
(b) What is the effective CPI?
