Embedded Systems-8 bit controllers: 6 Weeks

Abstract:

A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.

Introduction:

Some microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (milliwatts or microwatts). They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping (CPU clock and most peripherals off) may be just nanowatts, making many of them well suited for long lasting battery applications. Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor (DSP), with higher clock speeds and power consumption.

Prospects:

Microcontrollers are widely used in a variety of small appliances, as technology development, its not only cheap, but more powerful. As household appliances, handheld consumer electronics products, hand-held communication devices and automotive electronics market-driven areas, the use of microcontrollers and showed a growing trend of upgrading.

Training Objective:

This course is designed to ensure that students of Engineering College with academic capabilities will have the skill set needed to deal with the challenges involved in real-world Embedded Technologies to meet the needs of industries both today and in the future.

The course considers programming and device design techniques which can help to ensure that 8 bit single-processor embedded systems are reliable.

The course is taught mainly using the 8051 Microcontrollers, ASM51 assembler, keil compiler and embedded C programming language, circuit designs, hardware design.
