Answer 1

1. Data path for add

R format of add instruction:

field	op	rs	rt	rd	shamt	funct
numbits	6	5	5	5	5	6

The image below contains the data path for add:

2. Data path for lw (load word)

I format of lw instruction:

field	op	rs	rt	immediate
numbits	6	5	5	16

The image below contains the data path for lw:

3. Data path for sw (store word)

I format of sw instruction:

field	op	rs	rt	immediate
numbits	6	5	5	16

The image contains the data path for sw:

4. Data path for j (jump)

J format of j instruction:

field	op	address
numbits	6	26
