A memory system has the following performance characteristics: Cache Tag Check time: 1ns Cache Read Time: 1ns Cache Line Size: 64 bytes Memory Access time (Time to start memory operation): 10 ns Memory Transfer time: 1ns/memory word Memory Word: 16 bytes The processor is pipelined and has a clock cycle of 500 MHz. The memory operation occupies one stage in the pipeline. If it takes longer, the pipeline is stalled. What is the memory stall time for a program that performs 100 memory reads of which 90 hit in the cache and 10 miss. Memory stall time is defined as the amount of time the pipelin spends stalled due memory operations.
