Download or read book Distributed Arithmetic Architecture for the Discrete Cosine Transform written by Dwight Poplin and published by . This book was released on 1997 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Discrete Cosine Transform is used in many image and video compression standards. Many methods have been developed for efficiently computing the Discrete Cosine Transform including flowgraph algorithms, distributed arithmetic and two-dimensional decompositions. A new architecture based on distributed arithmetic is presented for computing the Discrete Cosine Transform and it's inverse. The main objective of the design is to minimize the area of the VLSI implementation while maintaining the throughput necessary for video and image compression standards such as MPEG and JPEG. Several improvements have been made compared to previously published distributed arithmetic architectures. These include elimination of four lookup tables and implementation of the lookup tables using logic instead of ROM. A model of the proposed architecture was written in C. The model was used to verify the accuracy of the architecture and to do JPEG compression on a series of test images. Behavioral simulations were performed with a hardware model written in the Verilog hardware description language. These behavioral simulations verify that the hardware implementation matches the C model. The model was synthesized using the Synopsis synthesis tool. The gate count and clock rate of the design were estimated using the synthesis results.

This book was released on 2010-03-10 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recon?gurable computing (RC) systems have generated considerable interest in the embedded and high-performance computing communities over the past two decades, with ?eld programmable gate arrays (FPGAs) as the leading techn- ogy at the helm of innovation in this discipline. Achieving orders of magnitude performance and power improvements using FPGAs over traditional microp- cessorsis not uncommon for well-suitedapplications. But even with two decades of research and technological advances, FPGA design still presents a subst- tial challenge and often necessitates hardware design expertise to exploit its true potential. Although the challenges to address the design productivity - sues are steep, the promise and the potential of the RC technology in terms of performance, power, size, and versatility continue to attract application design engineers and RC researchers alike. The International Symposium on Applied Recon?gurable Computing (ARC) aims to bring together researchers and practitioners of RC systems with an emphasis on practical applications and design methodologies of this promising technology. This year’s ARC symposium (The sixth ARC symposium) was held in Bangkok, Thailand during March 17–19, 2010, and attracted papers in three primary focus areas:RC applications, RC architectures, and RC design meth- ologies.
