He died July 26, 2022, in an All-terrain vehicle accident.
Career
- From 1977 to 1979, he was a Senior Design Engineer at Motorola, where he specified and designed the microcode and the controller core of the MC68000 microprocessor, one of the first microprocessors designed by structured VLSI design.
- From 1979 to 1987, Tredennick worked on microcode and logic design for the IBM Micro/370 microprocessor at the Thomas J. Watson Research Center. While at IBM, in 1983/1984 he took sabbatical leave to teach computer organization, chip design, and the Flowchart Method at UC Berkeley.
- In 1986, Tredennick co-founded NexGen and was director of product development there in 1987-1988. NexGen later developed the Nx686 microprocessor which became the AMD K6 when the company was acquired by AMD in 1996.
- As Chief Scientist of Altera Corporation from 1993 to 1995 he began advocating Reconfigurable Computing as an essential paradigm shift in computer science, a topic he spoke and published on extensively.
