Paper Present optimization technique of Low Power and Area of FIR filter using different architecture. This technique is necessary for filters while required different sampling rates. The proposed device is FIR filter, it design by different way so that circuit complexity will be reduced. Multiplier, adders and latches are reduced by different logic due to which power and area in system is reduced at great extend. The results for power and area in each case are verified and report is presented. Simulation of the design done by Active-HDL which verified and implemented successfully. Then it is synthesized by using 45 nm library in synopsis tool with constraint of low power and area. Reduction of power consumption is important parameter for system. In the last two decades, many efficient algorithms and architectures have been introduced for the design of low complexity operation. Authors have given attention to the digit serial design that offers alternative low complexity in operations. Experimental results have shown the efficiency of the proposed optimization technique and the design of digit serial operations due to which the power dissipation of FIR filter is reduced. Digit serial style is best suited for implementation of digital signal processing system which requires moderate sampling rates. In this paper, an alternative approach for the design of digit serial architecture is presented.Keywords: VLSI-Very large scale integrated circuit, RTL-Register transfer logic, DSP-Digital signal processing, VHDL-Very high speed hardware description language, FIR-Finite impulse response, Active-HDL-Active hardware descriptive language
This Paper Presents Analysis of Multirate Signal Processing Modules using Voltage and Technology scaling. AMI 0.6 um, TSMC 0.35 um, and TSMC 0.25 um technologies are used for voltage scaling of Multirate modules. Transistorized circuit of Upsampler and Downsampler has been designed using different technologies and simulated on cadence platform. The circuit is verified and implemented successfully. Reduction of power consumption is important parameter for system. The proposed methodology provides a systematic way to derive circuit technique for high speed operation at a low supply voltage. Author has designed transistor level implementation of Multirate modules which has full custom design with different circuit topology and optimization level. The observations of parameters are taken at different voltage scale and comparative analysis report is presented.
The Black Box control and monitoring system for vehicles concept is derived from the aviation industry, a flight recorder, colloquially known as a black box; although it is now orange-colored for easy search, is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. With the advancement in technology and cost coming down, in our project we attempt to build similar device for our cars, not only this device will help us in post-crash analysis but also it will help us in quicker emergency rescue operation. Our research has been targeted towards building an integrated system for emergency rescue services in the event of a road accident. The purpose of the project is to find the accident location using GPS module and to send this location by means of sending a message using GSM module to the pre-coded number. This system is usually placed inside the vehicle. It reduces the time it takes for emergency rescue to arrive at the crash location.
