In our hypothetical robot control system‚ the task of robot joint trajectory computation‚ which needs 10–100 ms update time‚ is assigned to a processor. The processor is driven by a timer interrupt that updates 82 Introduction to Embedded System Design Using Field Programmable Gate Arrays the trajectory profile every 10–100 ms.

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

This above work uses microcontroller and the performances of this cryptosystem is analyzed by implementing the cryptographic algorithm TEA with key generation unit. The key generation unit uses the timers in microcontroller to generate the random bits. The work extends with implementing the two different modes of communication serial (UART) and wireless transmission (RF) to transfer the data from encryption unit to decryption unit. communication

ABSTRACT: A PC based electricity power management system has been designed and constructed. The designed PC based electricity power management system were achieved by the use of a timer software which acts as a computer User Interface control and a hardware which acts as a computer interface with the help of a parallel port. The design was done such that it allows different appliances to be assigned a specific operating time and

A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The

Weather it is developed nation or developing nation all electricity boards are facing two major issues 1. Power Theft 2. Collection of funds In the existing system the above two problems are non predictable and time consuming process respectively. To overcome these things in the proposed system Cal cards has developed and implemented
