Mips-Datapath-Simulator

This is a website for demonstration of how most of the basic instructions work in MIPS architecture. Supported Instruction set:

Instruction	Format
Add	add $rd, $rs, $rt
Sub	sub $rd, $rs, $rt
And	and $rd, $rs, $rt
Or	or $rd, $rs, $rt
JR	jr $rs
Add Immediate	addi $rt, $rs, immediate
Store Word	sw $rt, offset($rs)
Load Word	lw $rt, offset($rs)
Branch Equal	beq $rs, $rt, label
J	j label
Jal	jal label

Alu Control

Basic datapath needs to modification for some instructions. I didn't find any recources for combinational logic of alu control that can handle those instructions. I started with this design

then I modified the logic to cater for this.
