Q1: Suppose the hypothetical processor has two I/O instructions: (3+3+3)0011=Load AC from I/O0111=Store AC to I/OIn this case, the 12-bit address identifies a particular external device.

Problems in this exercise assume that individual stages of the datapath have the following latencies: Also, assume that instructions executed by the processor are broken down as follows: (a) What is the clock cycle time in a pipelined and non-pipelined processor? (b) What is the total latency of an lw instruction in a pipelined and non-pipelined processor?

Is it possible for the scheduler to juxtapose the commands in such a way that there is no need for any bubbles? If yes, give an example of how it can be done.

We will explore the impact of cache capacity on performance, focusing exclusively on the data cache and excluding instruction storage in the caches. Cache access time is directly linked to its capacity. For the sake of simplicity, let's assume that accessing the main memory takes 100ns, and in a specific program, 50% of instructions involve data access. Two distinct processors, denoted as P1 and P2, are engaged in executing this program. Each processor is equipped with its own L1 cache. L1 size L1 Miss Rate L1 Hit Time P1 64 KB 3.6% 1.26 ns P2 128 KB 3.1% 2.17ns (a) What is the AMAT for P1 and P2 assuming no other levels of cache?
