The following MIPS assembly code contains a mistake that violates the MIPS convention in terms of using stack for storing/protecting registers. What is the mistake and how should it be fixed? Correct the corresponding lines in the code. For the corrected code, sketch the stack frame contents at the time when the instruction ‘move $s1, $a1’ is being executed. f: addi $sp, $sp, 12 sw $ra, 8($sp) sw $s1, 4($sp) sw $s0, 0($sp) move $s0, $a0 move $s1, $a1 #...

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

List the read after write (current instruction is reading certain registers which haven’t been written back yet) data dependencies. As an example , 3 on 1 ($s2) shows instruction 3 has data dependency on instruction 1 since it is reading register $s2. b. Assume the 5...
The classic five-stage pipeline MIPS architecture is used to execute the code fragments. Assume the followings: Register write is done in the first half of the clock cycle; register read is performed in the second half of the clock cycle, Branches are resolved in the SECOND stage of the pipeline and the architecture does not utilize any branch prediction mechanism Forwarding is FULLY supported. Assuming there is no dependence other than one(s) given in the code, show the pipeline diagram....
