Computer Organization & Architecture

Intorduction To Computer

A computer is a multipurpose electronic device that can receive, process and store data

Digital Logic

Digital, or boolean, logic is the fundamental concept underpinning all modern computer systems.

Digital Logic Simulator

A logic simulator is a computer program that allows designers and experimenters to conduct virtual tests of complex digital circuitry before working with any hardware

MIPS(Microprocessor without Interlocked Pipeline Stages)

MIPS or Microprocessor without Interlocked Pipeline Stages is a reduced instruction set computer (RISC) instruction set architecture The first commercial MIPS model, R2000 was announced in 1985.

MIPS(Microprocessor without Interlocked Pipeline Stages) Simulator

SPIM is a MIPS processor simulator, designed to run assembly language code for this architecture. The program simulates R2000 and R3000 processors, and was written by James R. Larus while a professor at the University of Wisconsin-Madison.

Language of the Computers

Introduction - Assembly Language The basic job of a CPU,its excute lots of instructions.The set of instructions a particular CPU implements is an Instruction Set Architecture (ISA),few examples: 1) Intel 80x86 (Pentium 4) 2)IBM/Motorola 3)PowerPc (old Macintosh) 4)MIPs 5)Intel IA64 Different CPU implement different sets of instructions.

The Processor

Introduction - A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and writeback.

Memory Organization

Introduction -A memory or a data byte, or a word, or a double word, or a quad word may be accessed from or at all addressable locations with a similar process would be used to access from all locations and there is would be equal access time for a read or for a write that is independent of a memory address location.

Input and Ouput

In this blog I will discuss on input/output procedures and devices .External device are not generally connected directly int the bus structure of the computer.I/O module is an interface for the external devices (peripherals) to CPU and memory.

Parallel Processing

Introduction to Parallel Processing - In computers, parallel processing is the processing of program instructions by dividing them among multiple processors with the objective of running a program in less time. - In the earliest computers, only one program ran at a time.
