EC1318 MICROPROCESSORS AND APPLICATIONS
1. INTRODUCTION
Organization of Micro Computers – Organization of 8085: Architecture, Internal Register Organization and Pin Configuration – Instruction Set of 8085 – addressing modes - instruction and machine cycles with states and timing diagram. Methods of 8085 programs and 8085 assembly language.
2. INTERFACING AND I/O DEVICES
Need for Interfacing – Memory Interfacing: address space partitioning – address map – Address decoding – Designing decoder circuit for the given address map – Bus connection and Z – line Control – Access Time Computations.
I/O Interfacing: Data transfer schemes – programmed Synchronous and asynchronous – Interrupt driven Transfer – Multiple devices and multiple interrupt levels – enabling disabling and masking of interrupts.
DMA transfer: Cycle stealing – Burst mode – Multiple DMA devices – DMA transfer in 8085 system – serial data transfer.
3. INTERFACING DEVICES
Programmable peripheral device – programmable interval timer (8253) – Programmable communication interface (USART) – Programmable interrupt controller – Programmable DMA Controller (8257) – Programmable Keyboard/ display controllers.
4. DESIGN USING PERIPHERAL DEVICES
Interfacing A/D and D/A converters – Matrix Keyboard design using 8255 using 8085 programs. Designing real time clock, detecting power failure, detecting presence of objects using 8253 – Design of Keyboard and display interfacing using 8279 – Design of digital transmission with modems and telephone lines using 8251 A.
5. MICROPROCESSOR APPLICATIONS
Temperature monitoring system – Automotive applications – Closed loop process control – Stepper motor control.
