Consider a new variant of the sw instruction (sw_inc) that increments the base register by 4 (so as to point to the next memory word) after storing the contents of the source register into memory. The instruction sw_inc $s0,500($s1), for example, would have the same effect as the following two instructions: sw $s0,500($s1) addi $s1,$s1,4 Describe the modifications to the single cycle datapath that would be needed to implement sw

A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.
_____ is a CPU design technique in which instruction execution is divided into multiple stages and different instructions can execute in different stages simultaneously.
Here, each instruction receives its own data independently of how other instructions get theirs. We utilize: A Multiple Data/Instruction B Multiple Data/Instruction C Singular Data Single Inst D Singe Inst Multiple
In this case, every instruction receives its own data, independent of how the data for other instructions is obtained. We make advantage of a: A Multiple Data/Instruction B Multiple Iterations of Data or Instruction C Singular Data Single Inst D Singe Inst Multiple

Given a memory load instruction, "mov R0; [R1+1000]," please give the input that should be selectedat each multiplexer. You can write "none" for the multiplexers that are not used for this instruction.(a) MUX1:(b) MUX2:(c) MUX3:(d) MUX4:
A subtraction instruction takes two operands, subtracts the first from the second, and the result goes into the second. Write a 16-bit subtraction instruction, where... The first operand is stored at the memory address contained within the %edx register. (NOTE: To be clear, the %edx register contains the memory address OF the operand, not the operand itself! Recall the syntax of "indirect addressing," to use here.) The second operand -- also where the result shall be stored -- is stored directly in the 16-bit %bp register. Type the appropriate assembly language instruction here:
Home Work: Execute the following instruction using all previous instruction format types: S = F-(C*B)+M
Given R = 20, PC = 12 and index register X = 15, show the value of the accumulator for the following instructions. All memory locations Q contain the value Q + 2. Each instruction uses three memory locations. a) LDAC 10 b) LDAC@10 c) LDAC R
Home Work: Execute the following instruction using all previous instruction format types: 1- X = (A + B)* (C + D) 2- S = F-(C*B)+M 3- N= (A+B*C)/ (F*E)
