Difference between CISC and RISC:
CISC stands for Complex Instruction Set Computer. Most PC's use CPU based on this architecture. For instance Intel and AMD CPU's are based on CISC architectures. Typically CISC chips have a large amount of different and complex instructions. In common CISC chips are relatively slow (compared to RISC chips) per instruction, but use little (less than RISC) instructions. MCS-51 family microcontrollers based on CISC architecture.
RICS stands for Reduced Instruction Set Computer ....etc

INTRODUCTION
In the past, adding speech recording and playbackcapability to a product meant using a digital signalprocessor or a specialized audio chip. Now, using asimplified Adaptive Differential Pulse Code Modulation(ADPCM) algorithm, these audio capabilities can beadded to any PICmicro device. This application note willcover the ADPCM compression and decompressionalgorithms, performance comparison of all PICmicrodevices, and an application using a PIC16C72 microcontroller.

ABSTRACT
A microcontroller is sometimes described as a computer on a chip because it contains all the features of a full computer including central processor, in-built clock circuitry, ROM, RAM, input and output ports with special features such as serial communication, analogue-to-digital conversion and, more recently, signal processing.
The smallest microcontroller has only eight pins but some having 68 pins are also being marketed. In the last five years, the prices of microcontrollers have dropped by 80% and a ....etc

The two divergent paths of Microcontroller and DSP may cross occasionally with each performing both tasks. Barriers to entry depend on peripherals, filling the data pipe, and quality of development tools. Designers of today's emerging systems that require both real-time control as well as analog signal processing are looking for ways to reduce cost and speed development time in a market that becoming increasingly competitive. Both technical and personal considerations rule. For a microcontroller engineer to consider a DSP or for a DSP engineer ....etc

VEHICLE MONITORING AND CONTROL SYSTEM USING MICROCONTROLLERS
ABSTRACT:

It is observed that most of the accidents occur due to the driverâ„¢s ignorance of traffic and safety rules. It is a practice for the drivers to drive the vehicle beyond permitted limits. Depending on the terrain, and other conditio ....etc

ABSTRACT

The 8051 is one of the most popular microcontrollers in use today. Many derivative microcontrollers have since been developed that are based on—and compatible with--the 8051. Thus, the ability to program an 8051 is an important skill for anyone who plans to develop products that will take ....etc

Speed Control of 3-Phase Induction Motor Using PIC18 Microcontrollers
INTRODUCTION
Induction motors are the most widely used motors forappliances, industrial control, and automation; hence,they are often called the workhorse of the motion industry.They are robust, reliable, and durable. When poweris supplied to an induction motor at the recommendedspecifications, it runs at its rated speed. However,many applications need variable speed operations. Forexample, a washing machine may use different speedsfor each wash cycle. Histor ....etc
