 (a) [5 points] Please write a C code to implement the convolution function in our case study. Please make sure that your code is comprehensive with sufficient comments.

(b) [5 points] Please convert your C code to an assembly code. No optimization is needed here. You can use any instruction set architecture, but please make sure that your code is comprehensive with sufficient comments.

(c) [5 points] Suppose that we have a simple 5-stage pipelined processor here. The pipeline stages are IF (instruction fetch), ID (instruction decode/register), EX (execution), MEM (memory), and WB (write-back), as shown in the figure below. The pipeline is in-order issue and in-order execution with ideal one cycle-per-instruction (CPD). It executes a branch instruction in the EX stage. It can detect hazards, but does not support forwarding between pipeline stages.

(d) [5 points] To improve the pipeline performance in the previous question, we would like to reduce the impact of control hazards by adding branch prediction to the processor pipeline. Please describe how this can be done and how it affects the performance.

(e) [5 points] To further improve the pipeline performance in the previous question, we would like to reduce the impact of data hazards by unrolling the loop. Please describe how this can be done and how it affects the performance.

(f) [5 points] Now, let us take the data memory into consideration. Assume each memory access takes 10 cycles, and there is a processor data cache to speed up the memory access for reused data. If an access hits the data cache, then the processor would not stall. Suppose the data cache is a direct-mapped cache which has 16 blocks and each block has 16 bytes. Estimate the data cache miss rates for M=1, 4, and 8.

(g) [5 points] Can "blocking" be used to reduce the cache misses in the previous question? If yes, please rewrite the code with blocking and estimate the performance benefit of blocking.

(h) [5 points] Suppose we want to apply the same convolution kernel to many independent input sequences, can we take advantage of multithreading to increase the performance? Please describe how such multithreading can be done, or why it cannot be done.
