1) Instruction Design

Take the SRC (Simple Risc Computer, link) instruction sequence provided below and determine the operation of the sequence (explain this operation in words). Then propose a new instruction to the SRC to accomplish the same thing. You must provide abstract RTL and concrete RTL for the new instruction based on the 1-bus architecture from the textbook. If required, you may modify the architecture.

shr r0, r1, 15

andi r0, r0, 1

addi r2, r1, 0

lar r31, done

brzr r31, r0

la r0, 0xFFFF

shl r0, r0, 16

or r2, r1, r0

done: …

Note: r0 is used only as a temporary register in this code sequence and should not be part of your new instruction. Your new instruction should be of the form new_instr rn, rm and should not affect any other general purpose registers than rn and rm (in the above code sequence, rm would be r1 and rn would be r2).

2) Computer Architecture (the FRACTION computer)

The use of floating point numbers (or fixed point for that matter) inherently introduces error into

computations. To remove all error, all computations should be performed as fractions. Therefore, the FRACTION is proposed as an “exact” computer architecture.

The core concept to the FRACTION is a new data type, the fraction. A fraction is a 32-bit piece of data, comprised of a 16-bit numerator in the upper half of the data, and a 16-bit denominator in the lower 16 bits.

Numerator (16-bits)

Denominator (16-bits)

The proposed architecture then performs standard fraction arithmetic (+, -, ?, ?). The standard ALU on our existing architecture can handle all standard integer based arithmetic, but there are several functions required to support fraction arithmetic. To manage this extra capability, we modify the 1-bus SRC architecture to include a new functional unit called the Fraction Unit (FrU) in addition to the standard ALU. The FrU has several proposed functions to assist in fraction arithmetic:

LCM

Least Common

Multiple

Computes the least common multiple of 2…

SOALAN TUGASAN /ASSIGNMENT QUESTION

A computer system may contain many components that need to communicate with each other. As a solution, a bus is used to establish device connections. A bus consists of the physical parts, like connectors, wires, and a bus protocol. The wires can be partitioned into separate groups, namely control, address, data and power.

Discuss the advantages and disadvantages of using a bus.

What is bus arbitration? Describe the bus arbitration problem as well as centralized and decentralized (distributed) arbitration schemes.

Question A:

Advantages of bus

The advantages of bus were identified correctly with excellent explanation

Disadvantages of bus

The disadvantages of bus were identified correctly with excellent explanation

Question B:

Bus arbitration problem

Bus arbitration was defined. Its problem was identified correctly with complete explanation

Centralized arbitration scheme

Detailed description on the three types of centralized arbitration scheme with exact diagrams

Decentralized arbitration scheme

Criteria Qa. Advantages of bus The advantages of bus were identified correctly with axcellent explanation Qa. Disadvantages of bus The disadvantages of bus were identified correctly with axcellent explanation Qb. Bus arbitration problem Bus arbitration was…

hi,

I have case study in Computer Architecture from book Computer Architecture A Quantitative Approach Fourth Edition.

I have solutions, but I want to more explain how can i answer it. And explanation be on presentation ( powerpoint) question by question Because required me to explain solutions.Dear I need illustrate steps for each answer and how to solve it ? because I have presentation in front of students I should be explain answers.

Computer architecture is the combination of software and hardware that is organized in such a fashion as to deliver the machine’s intended performance characteristics. Therefore, it is important for you to understand the basics.

Write a four to five (4-5) page paper in which you:

1.Describe Von Neumann architecture and explain why it is important. 2.Explain what a system bus is and why it is needed. 3.Summarize the use of Boolean operators in computer-based calculations. 4.Categorize the various types of memory and storage. 5.Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.
