Q2. Refer to datapath design on slide no. 26 with added blocks for jump instructions as shown in slide 33 in Chapter 4 (part 1). Let's assume a program has 500 instructions. These instructions are distributed as follows: R-Type 25% Immediate arithmetic (addi) 5% Load 20% Store 20% Branch 10% Jump 20% Answer the following questions (show calculations): a) How many instructions will use instruction memory? b) How many instructions will use data memory? c) How many instructions will use the sign extend block? d) In the clock cycles, where the sign extend block is not required, does it remain idle? If yes, how? If not, what happens to the output of the block in that cycle?

s. Convert the following C code to assembly language using vector operations. (Just do your best, make necessary assumptions, don't worry about syntax too much.) for (i-0;i <300; i++) { c_re[i] = a_re[i] b_re[i]-a_im[i] * b_im[i]: c_im[i] - a_re[i] b_im[i]+a_im[i] * b_re[i];
(a) In MIPS machine language, the R format instructions need an additional field (the “funct” field) to specify the instruction type (“add”, “sub”, etc.). Why can’t this be done using just the 6-bit “op” field, which all MIPS instructions have, instead? (b) Give a sequence of MIPS assembly language instructions that adds the contents of $s0 and $s1, storing the result into $s0, if the contents of $s1 are greater than 6. Otherwise, the contents of $s0 should be incremented by 28. In either case, afterwards the contents of $s0 should be copied into $s2. (c) Suppose that the starting address of an array of words is stored in $s0. Give a MIPS assembly language instruction that loads the contents of the second word in the array into $s1. (d) Suppose that A and B are defined using “A: .word 0”, and “B: .space 100”. Give a sequence of MIPS assembly language instructions that calls a procedure “P” with its two arguments being the contents of A and the address of B, using the standard procedure…
