Description: Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications.

Description: Modern Circuit Placement: Best Practices and Results describes advanced techniques in VLSI circuit placement which is one of the most important steps of the VLSI physical design flow. Physical design addresses the back-end layout stage of the chip design process. As technology scales down, the significance of interconnect optimization becomes much more important and physical design, particularly the placement process, is essential to interconnect optimization.

Description: ICCAD 2004 Faraday Mixed-size Benchmarks with routing information
Faraday Corp. recently released three benchmarks, originally intended
for comparisons between structured and conventional ASICs. We apply to
these benchmarks a standard ASIC design flow to generate five
mixed-size designs. Faraday benchmarks include three commonly-used
functional blocks: (I) 16-bit DSP, (II) 32-bit RISC CPU and (III)
DMA. Other details on these benchmarks such as the EDA Tools used by
Faraday, implementation conditions, settings etc. can be found in on
the faraday web-site. To minimize the impact of routing on the results
of the accounted placement approaches, we avoid clock-tree generation
and power routing in our flows. However, both clock-trees and power
rails can be built on theses benchmarks. Following is the description
of our ASIC flow which we used for generating the mixed-size
benchmarks from the original netlists. Platform: |
