Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer. 

Question

Forwarding
In this exercise, we examine how data dependencies affect execution in the basic 5-stage pipeline
described in COD Section 4.5 (An overview of pipelining).
Problems in this exercise refer to the following sequence of instructions:
1) add St1, St2, St3
2) sub St2, St1, St4
3) add St1, $t1, $t2
Assume there is full forwarding in this pipelined processor.
a) Write the sequence of instructions and include NOP (no operation dummy instructions) to
eliminate any hazards.
b) How many cycles will it take to process all instructions
Hint: Remember that only RAW dependencies matter in a pipeline.

I need help with the following question below. This exercise will help you understand the cost/complexity/performance tradeoffs of forwarding in a pipelined processor. Problems in this exercise refer to pipelined datapaths from Figure 4.45. These problems assume that, of all the instructions executed in a processor, the following fraction has a particular type of RAW data dependence. The type of RAW data dependence is identified by the stage that produces the result (EX or MEM) and the instruction that consumes the result (1st instruction that follows the one that produces the result, 2nd instruction that follows, or both). We assume that the register write is done in the first half of the clock cycle and that register reads are done in the second half of the cycle, so “EX to 3rd” and “MEM to 3rd” dependences are not counted because they cannot result in data hazards. Also, assume that the CPI of the processor is 1 if there are no data hazards. EX to 1st only MEM to 1st only EX to…

Below is a depiction of a loop in instruction memory address Охо TOP: instruction 1 Ox4 instruction 2 Ox8 instruction 3 OxC instruction 4 Ох10 conditional branch to TOP Assume that the branch target buffer is initially empty, and the prediction bits are set to Strongly Taken (ST). Fill in the blanks On the first pass through the loop we take the branch. The branch target bits are now We suffer stalls. On the second pass through the loop we don't take the branch. The branch target bits are now We suffer stalls. On the third pass through the loop we don't take the branch. The branch target bits are now We suffer stalls. On the fourth pass through the loop we don't take the branch. The branch target bits are now We suffer stalls.
Multicycle execution is better than single cycle execution since it is: a. Every operation is completely carried out within a single clock cycle b. Break up operation so that each stage is executed in 1 clock cycle and allow skipping of unused stages. c. The maximum clock frequency is determined by the slowest instruction in the instruction set. d. A form of parallelism since more than one instruction is executed by the processor in any given cla

:- We will be implementing a new instruction within the MIPS architecture. New instruction will decrement a Variable stored in a memory location and store the decremented value in a register (Rt). This new instruction will be called DECR. Its usage and interpretation is Usage: DECR Offset(4*Rs),Rt Interpretation: Reg[Rt]= Mem[4*Rs+Offset] - 1 Which blocks are used and which control signals are generated for this instruction. How would the Instruction code fields look like ? Do we need to add an extra hardware logic, explain ? (You may draw a simplified datapath flow)

Th is exercise is intended to help you understand the relationship between forwarding, hazard detection, and ISA design. Problems in this exercise refer to the following sequence of instructions, and assume that it is executed on a 5-stage pipelined datapath:add r5,r2,r1lw r3,4(r5)lw r2,0(r2)or r3,r5,r3sw r3,0(r5)> If there is no forwarding or hazard detection, insert nops to ensure correct execution.> Repeat above step, but now use nops only when a hazard cannot be avoided by changing or rearranging these instructions. You can assume register R7 can be used to hold temporary values in your modifi ed code.> If the processor has forwarding, but we forgot to implement the hazard detection unit, what happens when this code executes?
