Question

Write MIPS code to perform addition of two unsigned numbers in registers $t1 and $t2 and then verify whether the result has overflowed the 32-bit long destination register $t3. Explain the overflow logic with comments to elaborate upon each line of MlPs code. b. Indicate with a diagram how the same logic can be implemented in hardware. c. Explain with a flow chart and architecture diagram hardware efficient division algorithm may be performed d. Explain why massively parallel implementation of the division algorithm not possible?

Explanation / Answer

addu $v0, $a0, $a2 # add least significant word nor $t0, $a2, $zero # ~a2 sltu $t0, $a0, $t0 # set carry-in bit (capturing overflow) addu $v1, $t0, $a1 # add in first most significant word addu $v1, $v1, $a3 # add in second most significant word jr $ra
