Part 2: Intro to MIPS 1. a. Provide the type and assembly language instruction for the following binary value: (0010 0001 0010 1001 0000 0000 0000 0001)/2) b. Provide the type and hexadecimal representation of following instruction: sw $t5,32($t2) c. Provide the type, assembly language instruction, and binary representation of instruction described by the following MIPS fields (all numbers are represented in decimal): op=0, rs=3, rt=2, rd=13, shamt=0, funct=36

4. By assuming that 35 is a two digit number, consider memory storage of a 64- bit word stored at memory word 35 in a byte-addressable memory (a) What is the byte address of memory word 35? (b) What are the byte addresses that memory word 35 spans? (c) Draw the number 0XF1234567890ABCDE stored at word 35 in both big-endian and little-endian machines. Clearly label the byte address corresponding to each data byte value.

Translate the following C code to MIPS assembly, assuming that the variables f, g, h, i, and j correspond to registers $50, $s1, $s2, $s3, and $54 respectively. Also, assume that the base addresses of arrays A and B are contained in $56 and $s7 respectively, and that each element of arrays A and B are 4-byte words: B[8] =A[i] + A[j]; Which of the following MIPS assembly code snippets correctly performs the above operation? sll $t1, $s3, 2; add $t1, $56, $t1; lw $12, 0($t1); sll $t1, $s4, 2; add $11, $s6, St1; lw $13, 0($t1); add $12, $12, $t3; sw $12, 32($s7) sll $t1, $s3, 2; add $11, $s6, $t1; lw $12, 0($t1); sll $t1, $s4, 2; add $11, $s6, $t1; lw $13, 0($t1); add $t4, $12, $t3; sll $15, $t0, 2; add $15, $s7, $15; sw $t4, 32($15) Iw $11,0($s3); Iw $12, 0($s4); add $13, $11, $12; sw $13, 32($s7) sll $t1, $s3, 2; lw $12, 0($t1); sll $t1, $s4, 2; lw $13, 0($t1); add $t4, $t2, $t3; sw $t4, 32($s7)

What is the assembly language equivalent of each of the binary machine langauage instructions? Assume the format described in fig 6.13 and the numeric op code values shown in fig 6.5. a. 0101001100001100 b. 0011000000000111

Q.8. are missing. The assembler generates a relocatable code. All references use direct addressing. Write the values of the location counter (LC) and the contents of the symbol table, and also fill in the missing references in the machine code. (Assume that 3 bytes are allocated for each instruction and WORD pseudo-operation allocates 3 bytes and stores the given number at that byte.) Given the following assembly language program and its equivalent machine language code where some references START LC Machine code INST1 ЗА 00 00 Symbol Table L1: INST2 D1 D5 ?? ?? JZR L1 7B ?? ?? HLT 4C 00 00 D1: WORD 5 00 00 05 END
