Microprocessor and Embedded Systems

Upon the successful completion of the course, students will be able to: 1. develop an ALP in 8085 microprocessor using the internal organisation for the given specification; 2. describe the architecture and functional block of 8051 microcontroller; 3. develop an embedded C and ALP in 8051 microcontroller using the internal functional blocks for the given specification; 4. explain various peripheral devices such as 8255, 8279, 8251, 8253,8259 and 8237; and 5. explain microcontroller application and basic architecture of PIC, ARM and ATMEGA processors.

A basic microprocessor system: the CPU, memory, I/O, and buses subsystems, basic operation of a microprocessor system: fetch and execute cycle, the architecture of some typical 8-bit, 16-bit microprocessors (INTEL, MOTOROLA) and their features; programming model in real mode: registers, memory, addressing modes; organisation of the interrupt system, interrupt vectors, and external interrupts, implementation of single and multiple interrupts in real mode; programming model in protected mode: registers, memory management and address translation, descriptor and page tables, system control instructions, multitasking and memory protection, addressing modes, and interrupt system; memory interfacing and address decoding; I/O interfacing: memory mapped i/o, isolated i/o, bus timing, i/o instructions; peripheral devices interfacing: 8255 PPI/6821 PIA, 8251 USART/6821 UART, DMA, Timer/Counter chips, etc; instruction set; assembly language Programming of INTEL and MOTOROLA microprocessors; and discussion of a typical system e.g. IBM PC, Apple Macintosh.
