The instruction MOVE $s4, $s6 transfers the contents of register to register .s6

Question

The instruction MOVE $s4, $s6 transfers the contents of register to register .s6 to $s4 s4 to $s6 The instruction J branch5 creates the address for branch5 by shirting bits 25-0 right 2 places and concatenating bits 31-28 of the Program Counter to it. shirting bits 25-0 left 2 places and concatenating bits 31-28 of the Program Counter to it. shifting bits 25-0 right 2 places. shifting bits 25-0 left 2 places. Which processor architecture allows multiple instructions to operate at the same time? Single Cycle Pipeline Branch instructions do cause a stall. T or F The 5 steps in the cycle all have the same time duration. List the 5 steps in the instruction cycle from first to last (1 - 5). Match the following 2 sets of instructions with the efficiency of forwarding using a pipeline. add $s0, $s1, $s3 Iw $s0. 100($a0) sub $s4, $s0. $s3 sub $s4, $s0. $s3 forwarding will allow the second instruction to be operated on time forwarding will allow a single cycle to be lost before the second instruction is one Match the MUX and its function. MUX with input to Write Register MUX with input to the ALU MUX with inputs from Memory and the ALU MUX with input to the PC Selects a LW or an R Type instruction to write to a register. Selects between the next sequential instruction or a branch type instruction. Selects cither the RD register or the RT register to receive new data. Selects to admit data to the ALU from the RT register or bits 15-0 22. What is the timing difference between a single cycle processor and a pipeline processor to execute 5 instructions if the times for each of the 5 cycles, measured in nano seconds,
