Computer organization refers to the operational unit and their interconnection that realise the architectural specification. Computer organization deals with how different part of a computer are organised and how various operations are performed between different part to do a specific task. The organization of the computer is defined by its internal registers ,timing and control structure ,and set of instruction that is uses.

Computer instructions are a set of machine language instructions that a particular processor understands and executes. A computer performs tasks on the basis of the instruction provided. The Register-reference instructions are represented by the Opcode with a 0 in the leftmost bit bit 15 of the instruction. A Register-reference instruction specifies an operation on or a test of the AC Accumulator register. Just like the Register-reference instruction, an Input-Output instruction does not need a reference to memory and is recognized by the operation code with a 1 in the leftmost bit of the instruction.

The remaining 12 bits are used to specify the type of the input-output operation or test performed. A set of instructions is said to be complete if the computer includes a sufficient number of instructions in each of the following categories:. Arithmetic, logic and shift instructions provide computational capabilities for processing the type of data the user may wish to employ. A huge amount of binary information is stored in the memory unit, but all computations are done in processor registers.

Therefore, one must possess the capability of moving information between these two units. Program control instructions such as branch instructions are used change the sequence in which the program is executed.

Input and Output instructions act as an interface between the computer and the user. Programs and data must be transferred into memory, and the results of computations must be transferred back to the user. A program residing in the memory unit of a computer consists of a sequence of instructions.

These instructions are executed by the processor by going through a cycle for each instruction. In computer architecture, input-output devices act as an interface between the machine and the user.

Instructions and data stored in the memory must come from some input device. The results are displayed to the user through some output device. Skip to content Computer organization refers to the operational unit and their interconnection that realise the architectural specification. An instruction comprises of groups called fields. These fields include: The Operation code Opcode field which specifies the operation to be performed.

The Address field which contains the location of the operand, i. The Mode field which specifies how the operand will be located. Register — reference instruction The Register-reference instructions are represented by the Opcode with a 0 in the leftmost bit bit 15 of the instruction.

Note: The Operation code Opcode of an instruction refers to a group of bits that define arithmetic and logic operations such as add, subtract, multiply, shift, and compliment. Input-Output instruction Just like the Register-reference instruction, an Input-Output instruction does not need a reference to memory and is recognized by the operation code with a 1 in the leftmost bit of the instruction.

Note The three operation code bits in positions 12 through 14 should be equal to Otherwise, the instruction is a memory-reference type, and the bit in position 15 is taken as the addressing mode I. When the three operation code bits are equal to , control unit inspects the bit in position If the bit is 0, the instruction is a register-reference type.

Otherwise, the instruction is an input-output type having bit 1 at position Instruction Set Completeness A set of instructions is said to be complete if the computer includes a sufficient number of instructions in each of the following categories: Arithmetic, logical and shift instructions A set of instructions for moving information to and from memory and processor registers.

Instructions which controls the program together with instructions that check status conditions. Input and Output instructions Arithmetic, logic and shift instructions provide computational capabilities for processing the type of data the user may wish to employ.

Instruction Cycle A program residing in the memory unit of a computer consists of a sequence of instructions. In a basic computer, each instruction cycle consists of the following phases: Fetch instruction from memory. Decode the instruction. Read the effective address from memory. Execute the instruction. Input-Output Configuration In computer architecture, input-output devices act as an interface between the machine and the user. The following block diagram shows the input-output configuration for a basic computer.

The input-output terminals send and receive information. The amount of information transferred will always have eight bits of an alphanumeric code. The transmitter interface receives information from the keyboard and transmits it to INPR. The receiver interface receives information from OUTR and sends it to the printer serially. Design of a Basic Computer A basic computer consists of the following hardware components.

UNIT-1: Basic computer organisation and design

This book takes the reader from the basic design principles of the modern digital computer to a top-level examination of its architecture. This book can serve either as a textbook to an introductory course on computer hardware or as the basic text for the aspiring geek who wants to learn about digital design. The material is presented in four parts. The first part describes how computers represent and manipulate numbers. The second part presents the tools used at all levels of binary design. The third part introduces the reader to computer system theory with topics such as memory, caches, hard drives, pipelining, and interrupts.

Computer organization refers to the operational unit and their interconnection that realise the architectural specification. Computer organization deals with how different part of a computer are organised and how various operations are performed between different part to do a specific task. The organization of the computer is defined by its internal registers ,timing and control structure ,and set of instruction that is uses. Computer instructions are a set of machine language instructions that a particular processor understands and executes. A computer performs tasks on the basis of the instruction provided. The Register-reference instructions are represented by the Opcode with a 0 in the leftmost bit bit 15 of the instruction.

The book covers the basics of computer architecture, explaining how computer memory works. It takes readers through input and output devices and how the commands are translated by the operating system. It also covers number systems, Computer Arithmetic, digital logic and Processor Structure and Function. In addition the book provides a few instruction sets for the students to understand the practical applications of the topics. It is an essential resource for anyone trying to understand advanced computer architecture and concepts such as parallel processing and multi-core computing.

Fundamentals of Computer Organization and Design

Description of basic computer Computers are the digital devices that performs the various computational task. Internal organization of the computer is defined by the sequence of microoperations it performs on data stored in its resisters. For best performance, it is necessary to design the compiles, the machine instruction set, and the hardware in a coordinated way.

This book focuses on the concepts that are the basis for computers. Organized into nine chapters, this book begins with an overview of the computer revolution. This text then explains the concepts and algorithms used in modern computer arithmetic. Other chapters consider the abstractions and concepts in memory hierarchies by starting with the simplest possible cache. This book discusses as well the complete data path and control for a processor.

Computer Organization and Architecture Tutorial. Designed as an introductory text for the students of computer science, computer applications, electronics engineering and information technology for their first course on the organization and architecture of computers, this accessible, student friendly text gives a clear and in-depth analysis of the basic principles underlying the subject. Architecture in computer system, same as anywhere else, refers to the externally visual attributes of the system.
