Unit -2 - Hand written Lecturer Notes for Part-1 & Part-2

INTERFACING AND I/O DEVICES

 As already discussed in class, unit-2 is classified into 3 types

1. Memory Interfacing
2. I/O Interfacing
3. DMA transfer.

Part-1 covers the following topics :

1. address space partitioning 
2.  address map 
3.  Address decoding 
4. Designing decoders circuit for the given address map 
5. Bus contention and 2 – line Control 
6.  Access Time Computations.

Part-2 covers the following topics : 

Data transfer schemes – programmed Synchronous and asynchronous –

Interrupt driven Transfer – Multiple devices and multiple interrupt levels – enabling disabiling

and masking of interrupts

1. Data transfer schemes
2.  Programmed Synchronous
