Question

Im having trouble with the following:

“Shift Remainder register left
setting rightmost bit to 0”

My attempt:
lui $s0, 1 # Shift Remainder register left by 1 bit

or should it be 1*4 = 4 instead of 1 for offset?

Answer 1

Do you have an instruction set reference? lui is Load Upper Immediate, it doesn’t shift the register, it shifts the immediate, and by 16 bits. So lui $s0, 1 just loads 0x00010000 into $s0.

To shift left, you can use the sll instruction, such as sll $s0, $s0, 1
