About Me ... • started in Music, transitioned to CS ... • graduate work at University of Pennsylvania (Moore School and Wharton) • research interests in functional programming and database management • taught CS 160 (and several others) as a UCSB adjunct almost 30 years ago • from startup-up to Fortune-100 ... • [1982] joined Digital Sound, early developer of DSP-based voice servers • [1987] co-founded Spectron, which offered industry’s first DSP RTOS (SPOX) • [1995] acquired by Dialogic, after fielding IA-SPOX for native signal processing • [1998] sold to Texas Instruments, after incubating mass-market DSP/BIOS • [2000] elected TI Fellow, and commenced thinking about “what’s next” • so now that I’m retired ... • continue to evolve real-time SW component technology at http://rtsc.eclipse.org • collaborate with PhD candidate (Ami Amar) on deeply-embedded SW platforms • champion “programming-in-the-large...in-the-small” as core to CS/ECE curriculum
10 Guiding Lights For Embedded SW Engr all that matters is working software!! there’s no such thing as portable SW, only SW that has been ported!! consider the alternative of porting HW to SW!! portable 6A 5 6B 3 4A 1 2A 7 4B 2B leverage the unlimited resources of your PC throughout the SW life-cycle!! a right – but late – answer is wrong!! focus on “worse-case” performance!! first rule of optimization... don’t!! functional correctness trumps performance!! correct test what you fly, fly what you test!! if you can’t see the problem, you can’t fix it!! plans are meaningless, planning is everything!! change is the only constant!! change only one variable at a time!! resilient maintain modularity at all cost!!
