Mpi Unit 2

The document is a syllabus for a course on Microprocessor and Interfacing. It outlines 8 units that will be covered in the course, including Introduction to Microprocessors, Microprocessor Architecture and Operations, the 8085 Microprocessor, Assembly Language Basics, 8085 Assembly Language Programs, Stack and Subroutines, I/O Interfacing, and Advanced Microprocessors. Unit 2 on Microprocessor Architecture and Operations is discussed in detail, covering topics like how a microprocessor works through fetch, decode, and execute operations, the roles of the ALU, registers, control unit, and memory. It also discusses the role of the clock in synchronizing the microprocessor.

 Microprocessor is a controlling unit.

 It is a small chip capable of performing ALU (Arithmetic


Logical Unit) operations and communicating with the other
devices connected to it.

 Microprocessor consists of an ALU, register array, and a


control unit.

 ALU performs arithmetical and logical operations on the data


received from the memory or an input device.

10

 Microprocessor accepts binary


data as input, processes data,
and then provides output based
on the instructions stored in the
memory.

 The microprocessor follows a


sequence:
 Fetch, Decode, and Execute.

Role of clock in Microprocessor


Role of clock in Microprocessor
14

 Every microprocessor has an internal


clock that regulates the speed at which it
executes instructions and also synchronizes it
with other components.
 Synchronization: Synchronization is the
coordination of events to operate a system in
unison.
 The speed at which the microprocessor
executes instructions is called clock speed.
 Clock speeds are measured in MHz or GHz
where 1 MHz means 1 million cycles per
second whereas 1 GHz equals to 1 billion
cycles per second.

Memory

 High speed and low latency memory but cost is higher and storage
capacity is lower.
Primary Memory
 It is volatile memory, so if power failure occurs the content of memory
will be lost.

 It is non-volatile auxiliary memory. It is a permanent storage space to


Secondary hold huge amount of data.
Memory
 It is comparatively cheaper and slower compared to main memory.
