Hello. I am Jonah Probell (普 仲朗),

Microprocessor Designer (微處理器高級設計師)

Digital Video Industry Analyst (多媒体産業分析)

Professionally

I combine the skills of a digital video expert and a microprocessor architect. For more than a decade I have designed digital hardware and specifically microprocessors. I have always been interested in making computers come alive to users through audio and video. That is done by the science and art of digital signal processing. I have participated in the revolutionary growth of processor performance from the world of audio processing in the 1990s to the world of video processing today.

I have worked for multi-national companies that develop chips for digital audio and video, for startup companies, and as an independent consultant. Each has its charms. The work that I do typically involves designing one or more of:

  • microprocessor logic for general-purpose or digital signal processing including:
    • ALUs (including SIMD)
    • fixed-point multipliers
    • load/store interfaces
    • system bus controllers
    • on-chip debug interfaces (for software development)
    • system peripherals
  • systems on a chip based around such microprocessors in
    • FPGA
    • standard cell ASIC / ASSP
  • such systems for the purposes of processing digital video
    • decoders and encoders
    • MPEG, H.264 (AVC), and others
    • DVD, set-top box, video conferencing, video phones, and others

There is a lot of engineering work experience on my resume. I enjoy the benefits and challenges of startup companies. I was employee 23 at Lexra and a founder of Ultra Data. The Ultra Data intellectual property and technology assets were acquired at the end of 2004.

I enjoy helping startups in the chip, semiconductor IP, and EDA businesses whenever I can. I run the digital video web site VideoBits.org. I also enjoy meeting other engineers in my field. I am always looking for the next great opportunity. So, let me know what you are working on.

I have published some papers and pending patents and written some of my own source code that I freely distribute.
