Previous Employment |
December 2001 to Present |
| Employer |
NVIDIA Corp. (www.nvidia.com) |
| Experience |
I am part of NVIDIA's world-class hardware design team, working on
the latest GPU architectures utilising leading edge deep-sub-micron ASIC technology.
|
|
January 2001 to November 2001
|
| Employer |
Believe Inc. |
| Experience |
Project lead for a 1MGate ASIC. The chip I was responsible for was
the key component in a switch matrix memory sub-system that was at the heart of Believe's unique hardware
ray-tracing supercomputer. Apart from overseeing a small team of HDL designers, I was responsible for
investigating, specifying and implementing the fault-tolerant memory request and transfer packet protocol.
This protocol was optimised to provide mimimum latency whilst providing full auto-retry of bad packets.

June 1998 to December 2000 |
| Employer |
3Dfx Interactive Inc. |
| Experience |
Played a major role in the design of the 500k gate video section of a multi-million gate ASIC for the
PC 3D graphics market. This involved research and development of various digital filter
architectures, specification and implementation of the design in Verilog and Module Compiler HDL
and subsequent synthesis and verification. At the time of the company’s demise, I was involved in the
design of a revolutionary triangle binning architecture for a future product.

|
February 1993 to May 1998 |
| Employer |
Miles Consultants Ltd. |
| Experience |
Design of in-vision station identification Logo and Clock generators.
This involved the integration of embedded microprocessors, high speed (270Mbps) serial digital
link technology, novel image storage architectures and large scale FPGA design.
Particular attention was paid to designing the systems for image quality and fault tolerance.
I also designed, wrote and maintained their web site. |

October 1987 to February 1993 |
| Employer |
Redshift Design |
| Experience |
Originally employed to design a complex, high speed digital image processor
board, I went on to design and manage many projects, a few of which are listed below. |
|
- Digital video D1 to D2 and D2 to D1 standards converters.
- Machine vision system for the printing industry to align photographic films.
- System for the digital recording and retrieval of analogue signals to and from video tape simultaneously with the video picture for a medical application..
- Low distortion discrete 30MHz BW differential amplifier for broadcast video.
- A video cross-point router controller.
- A pocket sized microprocessor based intelligent battery charge monitor.

Interests and leisure activities |
Computer Generated Imagery |
|
I enjoy all aspects of CGI including scene simulation, fractals, animation and
computer games. My particular interest is in the algorithms and techniques employed to achieve the most
realism.
|
Hot Air Ballooning
|
|
I have a Private Pilots Licence (Balloons and Airships) and I am (currently not) a member of the
British Balloon and Airship Club. I enjoy all the varied aspects of the sport and it is a good way
to see the countryside. Why not visit my ballooning page here.
|
Photography
|
|
In the past, I have developed and printed my own black and white and colour films. These days, my "darkroom" is very much more
digital and far less messy. I shoot mostly landscapes, architecture and of course balloons, though in recent years I've branched
out into portraits and astronomical imaging (Mars opposition of 2003).
|
Astronomy and Space Exploration
|
|
I am a member of the British Astronomical Association.
I regularly explore the fantastic sights that the night sky has to offer and I am an
avid follower of the various missions into space carried out across the world. I have also done volunteer work at the
Lick Observatory in California.
