4. Given below is the MIPS instruction set for the R and I format along with examples of some operations. The function and opcodes are given in hexadecimal system t (5 bits) funct (6 bits 20 Inst Format op (6 bits) rs (5 bits)rt (5 bits) 0 0 reg2 reg2 0 0 regl Su InstFormat op (6 bits rs (5 bits) addi regl regl re regl regl constant constant constant constant 23 2b constant InstFormat jump constant Table 1: MIPS Instruction Set Using this table answer the following questions (a) Consider the following C statements. Each is a separate statement. Registers for variables s0 to s7 map to numbers 16 to 23 (given in decimal system) and temporary registers t0 to t7 map to 8 to 15. Give the MIPS assembly code and the hexadecimal instruction for the codes (4 (5+5)-40) iv. while(i-k)(i-i+ 1} (b) The following binary numbers represent certain instructions. Assuming we are using the MIPS instruction set, give the pseudocode, in a C-like format, for each instruction (3*5-15) i. 0000 0010 0001 0000 1000 0000 0010 0000 ii. 1000 1110 0101 0001 0000 0100 1011 0000 iii. 0001 0010 0101 0001 0000 0100 1011 0000
