Don Gillies

About Don

"In a real-time system the correctness of a computation depends not only upon the logical correctness of the result but upon the time at which it is produced."

I coined this definition in 1988, and it has been 'appropriated' by researchers in the field, often without attribution. I actually borrowed it from someone else - can you guess who?

See the Wikipedia article on Rate-Monotonic Scheduling which I maintain and extended in 2004 and 2005.

Read some technical articles.

I am now a systems engineer working on adaptive video streaming for Qualcomm Inc. I work on practical network algorithms and architectures. Regrettably, I cannot accept new students since I have moved away from Vancouver for good.
