Nice project, but quite difficult to work with, because I only have a x resolution, so the bottom console is cut off and the window is not resizable Nice project. A few things could probably be slightly improved but it is very nice as it is for teaching. Please provide the ad click URL, if possible:. Help Create Join Login. Operations Management.

Branch: master. Find file Copy path. Raw Blame History. It checks for stall, empty and active states of decode stageand prints to the output file. If there is no forwarding, data dependency is checked at decode stage and halt the pipeline. Also, if predict taken technique is used, branch instructions target address is compared with the label of all instructions and correct target instruction is fetched in the next cycle.

Parameters: IF1 IN -- First Pipeline stage that simulates instruction fetching when the pipeline stage is either empty or active. It checks for state of pipeline and checks for data dependencies. If found any data dependency, stalls the pipeline.

Also, if predict not taken or flushing technique are used, branch instructions target address is compared with the label of all instructions and correct target instruction is fetched in the next cycle. Load and store instructions are processed in this stage. Offset is added to memory address and the content of resulted memory location is placed in the register in a load instruction. Where as, content of register is placed in the resulted memory address incase of store instruction.

Memory is allocated for each stage with the size of structure stage. Initially, set the state of each pipeline stage to empty and stage count to 0.

MIPS Assembly Language

From character buffer read the register, memory and code sections seperately and update Register[] array, Memory[] array and inst[] arrays. If Instruction fetch1 is not stall, move the instruction from fetch1 to fetch2 stage. If Instruction fetch2 is not stall, move the instruction from fetch2 to decode stage.

If decode is not stall, move the instruction from decode to execute stage.

If execute is not stall, move the instruction from execute to memory1 stage. If memory1 is not stall, move the instruction from memory1 to memory2 stage. If memory2 is not stall, move the instruction from memory2 to memory3 stage. If memory3 is not stall, move the instruction from mem3 to write-back stage. You signed in with another tab or window.

The program reads hex from a ASM file and stores the lines in an array. Then it is supposed to emulate the MIPS machine. I've been searching all around but have no idea how to even start. Does anyone have some ideas or even pseudo-code to get me on the right path? It appears they're 8 hex digits. This is nice, because MIPS instructions are 32 bits long. You need to keep track of a few registers inside the machine.

You know what the MIPS registers are, right? SPIM might be a good place to start looking at how such a program might be constructed. It's a MIPS32 simulator. This would be a big "switch case" on the opcode, and for each case you handle the particular instruction. The variables of your program would basically be your registers, and you will also have to simulate a memory somehow you should be able to allocate your whole memory once and for all as a big chunk of memory that you will handle and to handle the translation from the MIPS addresses to addresses in your chunk of memory.

Then dealing with the opcodes is basically a question of altering your registers and your memory. You might be able to benefit from your language to do some operations like sum, product, I'm not familiar with MIPS instruction set, but you might also have to do some address translation depending on the available addressing modes.

Sometimes, the flow might move the PC back. Ideally you'd also want to make this part of the "memory" unmodifiable, but it's not what you want to focus on first.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I'm supposed to write a C program that takes an. As far as formatting, etc I won't need help. I've been given code that covers that; however I'm struggling figuring out how to set up my pipeline registers. However, it does not make sense as an index into the register file.

You actually have to decode the instructionwhich you just fetched in the IF stage. The bitfields in the instruction index into the register file. The immediate obviously doesn't come from the register file, it comes from the instruction, because that's what immediate means.

The instruction also shouldn't be re-fetched as happens in newState. You can see here that the ID stage doesn't even use PC. It just passes it on to the EX stage, which calculates the branch target. Learn more. Asked 4 years, 9 months ago. Active 4 years, 9 months ago.
