Qus:2 List the fundamental design
issues in designing an instruction set.
Answer:
The fundamental design
issues in designing an instruction set:
1. Operation Repertoire: How many
and which operations to provide, and how complex operations should be?
2. Data Types: The various types of
data upon which operations are performed.
Qus:3 What is the meaning of
arithmetic associativity? Explain in brief.
Answer:
Arithmetic

cycle of an 8086 processor :
After
understanding of the instruction cycle of the processor, now let us learn about
the Read-Write cycles. Read Cycle is Data
Q5. Briefly explain Interrupt
Driven I/O.
Answer:
Interrupt
Driven I/O:
Using
Program-controlled I/O requires continuous involvement of the processor in the
I/O activities. It is desirable to avoid wasting processor execution time. An
alternative is for the CPU to issue an I/O command to a module and then
Qus:6 What is the difference
between Synchronous and Asynchronous Data Transfer?
Answer:
The difference between
Synchronous and Asynchronous Data Transfer:
Synchronous data
transfer:
In synchronous
data transmission, data is transmitted though a bit-stream, that transmits a
group of characters in a single stream. In this type of data transfer, the
transmission speed is synchronised at both the sender and receiver by
