Computer architecture:

Q1 Translation between C and MIPS: Assume that the variables a, b, c, d, and j are assigned to registers $s0, $s1, $s2, $s3, and $s4, respectively.

a. MIPS to C: For the MIPS assembly instructions below, what is the corresponding C statement?

sub $t1, $s1, $s2

sub $t2, $s3, $s4

add $s0, $t1, $t2

b. C to MIPS: For the C statement below. what is the corresponding MIPS assembly code?

f = (a+b) - (c+d);

Q2 Translation between C and MIPS: Assume that the variables f, g, h, i, and j are assigned to registers $s0, $s1, $s2, $s3, and $s4, respectively. Assume that the base address of the arrays A and B are in registers $s6 and $s7, respectively. C Code:

For the C statement below. What is the corresponding MIPS assembly code?

f = g + A[B[4]-B[3]];
