Question

Consider the following MIPS code: text a main: addi St0, $0, 62 addi $tl, $0, -28 addi $t2, $0, 20 addi $t3, S0, 3 add $t4, $tl, $to sub St4, $t4. St2 mult $t3, $t4 mflo St5 div $t5, $t4 mflo $t6 div $t2, $t3 1. Prepare a table where each column corresponds to one of the following registers: PC, HI, LO, So, to, ti, t2, t3, St4, St5 and St6. For each instruction in the MIPS code, write in th table entry: e appropriate the value of the program counter. Note: For line 2, PC has the value oxoo400000. the value of the registers that participate in the instruction, and indicate which register's content changed
