Professional background and interests
I run my own company, Embecosm, specializing in open source tools for embedded software development. In the past I have been CEO and CTO for Tenison Design Automation and held various positions at Marconi plc. From 1986-1995 I taught at Bath University School of Mathematical Sciences, where I wrote "Introduction to Compiling Techniques: A First Course using ANSI C, LEX and YACC" (McGraw-Hill, 1990, 1995, 2003).
My areas of technical interest are:
- Instruction set design and implementation
- Debuggers, particularly the GNU Debugger
- Hardware modeling, both cycle accurate and transactional
- Theoretical biology, particularly analytical modeling of enzyme kinetics
I have been, and am currently involved in a number of open source projects
- During 2001-2 I was an active contributor to the ArgoUML project, and wrote large parts of its user manual.
- I am currently an active to contributor to OpenCores, and maintain the OpenRISC architectural simulator and GDB port
- I take an active interest in the GNU Debugger project
I am married with two children and live in Bournemouth, UK. Non-work interests include my local church, politics, gardening, sailing and woodwork and of course my family.
