Modified Architecture for Distributed Arithmetic with Optimized Delay using Parallel Processing

Realization of Fir Filter Using Modified Distributed Arithmetic Architecture

This paper presents an efficient implementation of Finite Impulse Response Filter (FIR) using Distributed Arithmetic (DA) architecture. Here, the multipliers in FIR filter are replaced with multiplierless DA based technique. The DA based technique consists of Look Up Table (LUT), shift registers and scaling accumulator. Analysis on the performance of various filter orders with various partition...

Large Scale Image Processing Using Distributed and Parallel Architecture

--Enormous amount of images are uploaded and used via internet and this ratio is still drastically increasing .So there is instant need to handle this data and customize and filter it as per user and application requirement. This paper describe some parallel and distributed processing techniques like Hadoop, HIPI, Map reduce, CUDA, MPI to process massive database. Mapreduce based large-scale im...

distributed arithmetic با کارایی بالا

در این تحقیق، روش های پیاده سازی فیلتر با پاسخ ضربه محدود (فیلتر fir) مورد بررسی قرار می گیرد. برای پیاده سازی فیلتر fir از دو واحد(mac) multiply accumulate و distributed arithmetic (da) استفاده می شود. پیاده سازی فیلتر fir با da از 50 تا 80 درصد مساحت اشغالی را بهبود می دهد؛ همچنین توان مصرفی را نیز کاهش می دهد. روش هایی برای بهبود ساختار اولیه ی da نیز ارائه می شود که باعث افزایش کارایی فیلتر...

Arithmetic Unit Implementation Using Delay Optimized Vedic Multiplier with Bist Capability

The ever increasing demand in enhancing the ability of processors to handle the complex and challenging processes has resulted in the integration of a number of processor cores into one chip. Still the load on the processor is not less in generic system. This load is reduced by supplementing the main processor with Co-Processors, which are designed to work upon specific type of functions like n...
