ALUOp is a 2 bit signal, so ALUop0 and ALUop1 refer to the individual
bits of ALUOp. Note that ALUOop is not ALUctr from lecture, which means
it doesn't feed directly to the ALU. ALUop + the funct field of the
instruction generate the control signal to the ALU. Refer to figure
5.12 and 5.13 for more details.

Im confused regarding the ALUop0 vs ALUop1. I can't seem to figure out what
each refers to. There are ALUOp and ALUsrc outputs from the control, are
these what was meant?
Thanks for the kick in the right direction.
