Draw a MIPS processor that implements only three instructions: add, sub, beq only.
Draw a MIPS processor that implements only three instructions: add, sub, beq only.
Usc only the following MIPS instructions for assignment questions 3, 4 and 5: add, sub, addi, j, beq, bne, lw, sw. You may not need as many lines as we provide space for 4. (4 pts) Write a MIPS program starting at address 20 that writes a value of 488 to register $7. Next, you will test if register $10 is equal to register $7. If the values are equal, continue execution at address 48; otherwise set the value in...
The following MIPS program is to be run on a MIPS pipeline processor of 5 stages (IF-ID-EX-MEM-WB). Work out and diagram the optimal pipeline schedule using full forwarding from EX or MEM stages to any other stage, Draw the pipeline execution diagram for this code and then compute the pipeline CPI: addi $t6, $t6, 10 sub $t5, $t6, $t4 srl $t5, $t5, 2 sw $t5, 20($t5) lw $t2, 0($t6) add $t7, $t2, $t3 beq $t5, $t7, End
1. Given the following instruction sequence for the MIPS processor with the standard 5 stage pipeline $10, S0. 4 addi lw S2.0(S10) add sw S2,4(510) $2, $2, $2 Show the data dependences between the instructions above by drawing arrows between dependent instructions (only show true/data dependencies). a. Assuming forwarding support, in what cycle would the store instruction write back to memory? Show the cycle by cycle execution of the instructions as they execute in the pipeline. Also, show any stalls...
Convert the following MIPS instructions Into Machine Code Instructions. Assume the first Instruction starts at memory address 20000 slt $t1, $s1, $s0 beq $s1, $s2, L1 beq $t1, $zer0, L2 j Exit L1: add $s1, $s1, $s1 j Exit L2: add! $s1, $s1, 1 Exit:
1) The MIPS instruction set only contains two types of conditional branch instruction, beq and bne. Explain why the designers of MIPS considered this to be a sensible thing to do.
Using beq only, not bge! Translate the following C code to MIPS assembly code. Use a minimum number of instructions. Assume that the values of a, b, i, and j are in registers $s0, $s1, $t0, and $t1, respectively. Also, assume that register $s2 holds the base address of the integer array D. Comments are required. for(i=1; i<a; i++) for(j=1; j<b; j++) D[2*j] = i + j;

1 For a given processor bound workload the frequencies of instructions move (MOV), floating add (FADD), and floating multiply (FMUL), and the corresponding instruction run times, for a given processor are: FADD 10 300 Others 50 160 MOV Instruction Frequency 30 Time [nanosec] 100 FMUL 10 600 What is the MIPS indicator of this processor? Faster memory chips reduce the MOV time by 50%, and all other times by 20%. What is now the value of the MIPS indicator? The...
A designer decides to add a fused multiply-add (FMA) instruction to our MIPS processor. The instruction does the following operation on registers: A=A*B+C. What type of instruction format can we use to encode this new instruction? I, J, Need a new format or R

(60 points) The following instructions are executed on the 5-stage MIPS pipelined datapath. add r5,r2, r1 lw r3, 4(r5) lw r2, 0(r2) or r3, r5, r3 sw r3, 0(r5) (a) (20 points) List the data hazards in the above code. For each data hazard identified, clearly mark the source and the destination. For example you can say, there is a data hazard from instruction X to instruction Y on register Z.
