Shortwave Radio Demo | Andraka Consulting Group

http://www.andraka.com/shortwave.php

Conference and Journal Papers. What is a FPGA? What does a Logic Cell do? How are FPGA Programs created? The entire radio, with the exception of the A-to-D converter,is implemented in the FPGA! A tunable antenna preamp (Ameco TPA). Is connected directly to the A to D converter: there is no analog front-end. The audio output is produced with delta-sigma DACs implemented in the FPGA. Control is by a computer via an RS232 link to the FPGA. Tuning range: DC-20 MHz, 0.01 Hz resolution. 10 KHz output bandwidth.

The CORDIC Algorithm | Andraka Consulting Group

http://www.andraka.com/cordic.php

Conference and Journal Papers. What is a FPGA? What does a Logic Cell do? How are FPGA Programs created? What is all this CORDIC stuff anyhow? CORDIC is an acronym for COrdinate Rotation DIgital Computer. It is a class of shift-add algorithms for rotating vectors in a plane. In a nutshell, the CORDIC rotator performs a rotation using a series of specific incremental rotation angles selected so that each is performed by a shift and add operation. A survey of CORDIC algorithms for FPGAs. Ray Andraka, FPGA ...

FPGA or DSP | Andraka Consulting Group

http://www.andraka.com/fpgavdsp.php

Conference and Journal Papers. What is a FPGA? What does a Logic Cell do? How are FPGA Programs created? When should I use an FPGA instead of a DSP microprocessor? Designing DSP hardware is quite different than designing DSP for software based systems. In addition to the obvious considerations for hardware such as clocking, timing and so on, a hardware DSP designer also has to consider how an algorithm is going to map to hardware, as well as the availability of design talent and tools.

Conference and Journal Papers. What is a FPGA? What does a Logic Cell do? How are FPGA Programs created? Many of our designs are meticulously floorplanned to obtain the highest performance and density possible. People who have seen our floorplans have called them works of art, so we have decided to share a few of them. For the most part, these are built up out of placed macros, so floorplanning didn't take more than a day or two to do. Click on the floorplan thumbnails for the big picture.
