Question 0 Please NOTE that Section a and Section b in the following questions are separated problems. Question 1 The following problems deal with translating from C to MIPS. Assume that the variables f, g, h, i, and j are assigned to registers $80, $s1, $s2, $s3, and $s4, respectively. Assume that the base address of the arrays A and B are in registers $s6 and $87, respectively. Assume that the elements of the arrays A and B are 4-byte words: a. f - f + A[2]; b. B[8] = A[i] + A[j]; (1). For the statements above, what is the corresponding MIPS assembly code? (2). For the C statements above, how many MIPS assembly instructions are needed to perform the statement? (3). For the statements above, how many registers are needed to carry out the C statement using MIPS assembly code? The following problems deal with translating from MIPS to C. 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 $87, respectively. sub $50, $50, $51 sub $50, $50, $s3 add $50, $50, $51 b. addi $t0,$56, 4 add $t1,$56, $0 SW $t1, 0($t0) $t0, 0($t0) add $50, $t1, $t0 lw (4) For the MIPS assembly instructions above, what is the corresponding C statement? (5) For the MIPS assembly above, assume that the registers $80, $s1, $s2, and $s3 contain the values 0x0000000a, 0x00000014, 0x0000001e, and 0x00000028, respectively. Also, assume that register Ss6 contains the value 0x00000100, and that memory contains the following values: Address 0x00000100 Ox00000104 Ox00000108 Value Ox00000064 0x000000c8 0x00000120 Find the value of $s0 at the end of the assembly code. 6. For each MIPS instruction, show the value of the opcode (OP), source register (RS), and target register (RT) fields. For the I-type instructions, show the value of the immediate field, and for the R-type instructions, show the value of the destination register (RD) field.
