QEEE Session
On
Microprocessors and Microcontrollers - Memory Mapping and Peripheral Interfacing
15th, 21st & 22nd September 2016
QEEE Session on Microprocessors and Microcontrollers - Memory Mapping and Peripheral Interfacing was organized by IIT, Madras under D2S (Direct to Student) Program at Dronacharya Group of Institutions, Greater Noida on 15th, 21st & 22nd September 2016. B. Tech 3rd Year students of ECE & EEE Department attended the session atDGI, Greater Noida. The program was conducted by Prof. Ashok Jhunjhunwala, IIT Madras. The program was coordinated by Ms. Rasveen (Assistant Professor, Department of ECE) DGI, Greater Noida.
Day 1: 15th September 2016
On first day of the program Prof. Ashok Jhunjhunwala gave an introduction to processor board, memory mapping, processor architecture and processor chip in detail. He discussed the basic components and basic operations of 8085 /8086 processor family. He also elaborated execution unit, transmitting data, addresses and control signal of a processor. He explained the use of external memory which allows the permanent storage of large quantities of data. He gave an overview on Peripheral Interface Controller (PIC) which is designed to improve the performance of I/O operations from a computer's peripheral devices. The session focused on the basic concept of memory mapping, external memory and processor architecture. Session ended with Questionnaire.
Day 2: 21st September 2016
On the second day, Prof. Jhunjhunwala discussed the basics of polling and interrupt services. He explained interrupt service request (ISR), maskable /non - maskable interrupts, hardware interrupts and software interrupts. He described execution of interrupts, interrupt acknowledgment and the Interrupt Vector Table (IVT). He demonstrated the keyboard and keypad interfacing with the help of interrupt. The session ended with interaction of Prof. Jhunjhunwala with the participants and he resolved their queries.
Day 3: 22nd September 2016
Third session started with the uses of peripheral interface controller (PIC) in electrical circuits, small controllers and circuits that require a set amount of processing. He also discussed limitations and advantages of PIC architecture and building blocks for implementation registers. He described direct memory access (DMA), pin description and various modes of data transfer. He explained the 7 Layers OSI Standard Protocol for inter device communication.
The knowledge received from these sessions will be useful for the students in academics as well as in project work.
