Group 1
multu R1, R2 => Unsigned multiplication of 32 bits registers which outputs 64 bit value
- (HI, LO) = R1 * R2
- (HI, LO) = (00AABB11)16 * (00000100)16
- (HI, LO) = (00000000 AABB1100)16
mfhi R3 => move from HI
- R3 = 0000000016
mflo R4 => move from LO
- R4 = AABB110016
Group 2
divu R1, R2 => Unsigned division of 32 bits registers
- HI = Remainder of R1 divided by R2,
- LO = Quotient of R1 divided by R2
- HI = (00AABB11)16 % (00000100)16 = 0000001116
- LO = (00AABB11)16 / (00000100)16 = 0000AABB16
mfhi R3 => move from HI
- R3 = 0000001116
mflo R4 => move from LO
- R4 = 0000AABB16

You are given a homework processor (HPro) capable of addressing 32 8-bit (1 byte) wide registers. However, it has only 29 physical registers. Register RO, R1 and R31 are not physically implemented. Instead, every read from RO, R1 and R31 will return a constant zero (00000000), constant one (00000001) and all ones (11111111), respectively. Every write to RO, R1 and R31 will go to null (dummy write). Assume that all other registers have initially unknown (X) state (This in fact...
