Consulting Interests

Software:

CAD

I worked on the Plan9 electronic CAD system known as "CDA". I wrote a static checker smoke that looked for simple errors in MSI and LSI designs as well as a transmission line evaluation program that looked for ringing. I also created analog part libraries for the schematic editor.

Linux device drivers

I have written a Linux device driver for a PCMCIA synthesizer card

Audio DSP

I have developed a prototype melody matching algorithm from sung voice. This was done as preliminary work to index musical databases.

Gnusic

The Gnusic project involved the design of three boards: (1) a board containing 16 Yamaha synth chips with an associated DSP-16 mixer, (2) A multiprocessor DSP-16 board with 5 DSP-16s and associated interconnect and (3) a AES/EBU and SMPTE interface board.

Audio

I have been an expert witness on audio DSP hardware patents

RF measurement

I have been involved with prior art research
