Consulting Interests
I have consulted for a number of companies, large and small. I am
interested in various aspects of DSP system design including
software, hardware
and patents.
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.
Hardware:
- 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.
Patents:
- Audio
- I have been an expert witness on audio DSP hardware patents
- RF measurement
- I have been involved with prior art research
