Given the following machine code instructions (assuming the mini-Sparc RISC architecture discussed in class), what are the assembly language instructions? (When listing registers, just use register numbers, like R3 or R27) a) 1011 1100 1001 0001 0101 1111 0000 1001 b) 1101 0110 0101 0110 1010 0000 0001 0101 3. Given the datapath diagram utilized in class, list the letter corresponding to each of the following components: a) The input for the multiplexer that selects the first operand in an add instruction. b) The input for the multiplexer that selects the result of either the ALU or the shifter. c) The input for the decoder to turn on one register as the destination register.
