Supporting Assembly Codes In a few sentences, explain what each code blocks does and why. (10%) (c) In 150 words, describe what the ALU calculates for R and I type instructions and discuss using two examples what occurs in the MIPS pipeline when instructions take multiple cycles. [25%] (d) Consider a CPU with a byte-addressable main memory of 2 bytes and a block size of 4 bytes. Assume that a direct mapped cache consisting of 64 lines is used with this CPU
