ori - correct answer ori $t, $s, imm bitwise ORs a register ($s) and an immediate value (imm) ---> stores the result in a register ($t) ( loads $t with imm, if $s =$0 ) $t = $s | imm; advance_pc (4); ex: ori $8,$0,0x2 #put two's comp. two into register 8 ori $9,$0,0x3 #put two's comp. three into register 9 bitwise opertation - correct answer operates on one or more bit patterns ...

Lecture 3 1) Write the MIPS assembly language instruction to implement the C instruction given below. f = a - b; Assume the following a is in $s1 b is in $s2 c is in $s3 d is in $s4 f is in $s0 - correct answer sub $s0, $s1, $s2 Lecture 3 2) Write the MIPS assembly language instruction(s) to implement the C instruction given below. f = d + c - 3; Assume the following a is in $s1 b is in $s2 c is in $s3 d is in $s4 f is ...

mnemonic correct answers first part of assembly instruction i.e. add, addi..etc Design principles for MIPS Assembly correct answers 1. Simplicity favours regularity - Instructions with a consistent number of operands are easier to code and handle 2. Make the common case fast - MIPS only has simple and commonly used instructions 3. Smaller is faster (size of memory matters.) - reading from a small set of registers is faster 4. good design demands good compromise - MIPS make compromise...

A particular program takes 300 seconds total to run and it spends 200 seconds performing divides. Assume we can speed up the division operation. How much faster would divides need to execute to reduce the total program running time to 150 seconds? Is it possible to reduce running time to 75 seconds? - Answer- 4 times faster, No Which of the following are problems with using Millions of Instructions Per Second (MIPS for short) as a measure for comparing computers' performance? - Answer- While...

Instruction Set - correct answer the vocabulary of commands understood by a given architecture. MIPS operands - correct answer 32 registers 2^30 memory words Register #0: $zero used for - correct answer constant zero Registers # 2 and 3: $v0 and $v1 used for - correct answer Expression evaluation and re...
