SPIRAL Hardware

On this page we overview hardware design generators that we developed in this project and make available to the public. In each case you have to click on the link to be forwarded to the particular site.

DFT (Discrete Fourier Transform) Verilog IP Generator

We provide web interface access to our generator for customized DFT hardware. A simple web form allows the user to specify parameters that control tradeoffs between area and speed. From the parameters, the Verilog code is generated and can be downloaded and used under the included license. Go to the DFT website.

Multiplierless Constant Multiplication

We have developed algorithms and tools that generated multiplier blocks that multiply by one or several constants "multiplierless," that is, using only additions, subtractions, and shifts. Go to the multiplierless website.

DCT (Discrete CosineTransform) Verilog IP Generator

We provide web interface access to our generator for customized DCT hardware. A simple web form allows the user to specify parameters that control tradeoffs between area and speed. From the parameters, the Verilog code is generated and can be downloaded and used under the included license. Go to the DCT website.

Multiplierless FIR/IIR Filters

We provide a web interface to our generator for multiplierless finite impulse response (FIR) and infinite impulse response (IIR) filters.

Structured LDPC Codes

We develop FPGA implementation of a class of structured LDPC codes and analyze these codes. Go to the LDPC site.
