DETAILED CONTENTS

1. Hardware organization of computer system

 CPU organization: general register organization, stack organization, instruction formats(three address, two address, one address, zero address and RISC instruction).

Addressing modes: Immediate, register, direct, in direct, relative, indexed.

 CPU Design : Microprogrammed vs hard wired control.

 Reduced instruction set computers: CISC characteristics, RISC characteristics, and their comparison.

2. Memory organization

 Memory Hierarchy

 RAM and ROM chips, Memory address map, Memory connections to CPU.

 Auxiliary memory : Magnetic disks and magnetic tapes.

 Associative memory

 Cache memory

 Virtual memory

 Memory management hardware

 Read and Write operation

3. I/O organization

a. Basis Input output system(BIOS)

o Function of BIOS

o Testing and initialization

o Configuring the system

b. Modes of Data Transfer

o Programmed I/O : Synchronous, asynchronous and interrupt initiated.

o DMA data transfer

4. Architecture of multi processor systems

 Forms of parallel processing

 Parallel processing and pipelines, basic characteristics of multiprocessor

 General purpose multiprocessors’

 Interconnection networks : time shared common bus, multi port memory, cross bar switch, multi stage switching networks and hyper cube structures.
