You may not need as many lines 5: add, sub, addi, j, beq, bne, lw, sw. as we provide space for (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 register $7 to $10 $21 (contents of register $10 subtract contents of register...
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...
Consider the following MIPS assembly language instructions: addi $1, $2, 100 swr $1, 0($2): addi $rt, $rs, immediate # add immediate swr $rt, immedi ate ($rs) # store word write register These instructions are I-format instructions similar to the load word and store word instructions. The addi and swr instructions store a computed value to the destina- tion register $rt. The instructions do not require any physical hardware changes to the datapath. The effect of each instruction is given below....
Consider the following MIPS code: add $t3,$t2,$t1 lw $t4,0($t3) sw $t7,0($t3) add $t6,$t2,$t8 addi $t3,$t5,4 (a) Draw a general pipeline diagram from CC1 to CC5 (b) Can you identify the type of hazard in pipeline for executing the code? (c) What is the solution to the hazard? If NOP (noop or bubbles) have to be inserted to avoid hazard, where will you put them? (d) Put the code into the MIPS simulator and observe your findings. You may want to...
Edit: Not sure what more information you need. Write a MIPS assembly program to determine the range between pairs of numbers. Keep things very basic with instructions such as load (lw), store (sw), add (addi and add), subtract (sub), multiplication (mul), branch (beq and bne), jump (j), and set on less than (slt) instructions. Your program should meet the following functional requirements: Input: an arbitrary number of integer pairs (in all pairs, the first number will be the max value)...

Assume that our MIPS instruction subset is redefined to contain only the following instructions: Instruction Instruction fetch Register read & ALU operation Data Memory Register write decode 0 ns R-format 2ns 1 ns lw ns l ns 2 ns 5 ns 1 ns ns 1 ns ns 0 0 bne The table lists the times required for each step within each instruction. Recall that with the...
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
