INTERCONNECTION STRUCTURE

COA- INTERCONNECTIONS STRUCTURE

1. INTERCONNECTION STRUCTURE By Ms.V.VENNILA,MCA., M.Phil ., Assistant Professor, Bon Secours College for Women Thanjavur .

2. Interconnection Structures A Computer consists of a set of components(CPU , Memory , I/O Module) that are communicate with each other. The collection of paths connecting the various module is called interconnection structure. The design of structure will depend on the exchange that must be made between modules INTERCONNECTION STRUCTURE

3. MEMORY MODULE Memory module consists of n words equal length is assigned as unique numerical address Memory N words . . . n-1 READ WRITE ADDRESS INTERNAL DATA EXTERNALDATA DATA

4. I/OMODULE It is internal part of a computer that perform read and write operation . I/O Module M Ports Read Write Address Internal Data ExternalData Internal Data External Data Instruction Signal

5. Processor Module The processor read and write the data by processing the instruction. After processing , it use control signal to control overall computer system. CPU Instruction Data Interrupt Signal Address Control Signal Data

6. TYPES OF INTERCONNECTIONS Memory to Processor – The processor read an instruction or unit of data from memory. Processor to Memory - The processor writes unit of data to memory. I/O to Processor – The data reads from I/O device through I/O module. Processor to I/O – The processor sends data to I/O device.

7. BUS INTERCONNECTION

8. Bus interconnection is important component of computer: architecture. It is a communication channel. It connects various components of computer to communicate with each other. BUS INTERCONNECTION
