01 · A life in computing
The person behind the work
David Patterson helped establish reduced instruction set computing through the Berkeley RISC projects, showing how simpler instruction sets could support efficient processor designs. With John Hennessy, he promoted quantitative comparisons of architectures and wrote influential textbooks. His broader research includes reliable storage and parallel systems. He later worked at Google as well as Berkeley, continuing to connect architectural principles with the demands of practical computing workloads.
The contribution, explained
John Hennessy and David Patterson pioneered a systematic approach to designing and evaluating computer architectures. Their work on RISC and their teaching emphasised measurement, workload behaviour and trade-offs between hardware and compilers. A design should be judged by the performance it delivers on meaningful tasks.
Why it matters
Quantitative reasoning helped guide microprocessor development and made architecture choices easier to compare.
