CORRECTIONS
Tuesday’s article profiling Professor Anantha P. Chandrakasan misspelled the last name of Chandrakasan’s co-author in “Low-Power CMOS Digital Design.” He is Samuel Sheng, not Cheng.
The same article imprecisely described parallelism as running “computations on two processors at the same time.” Parallel computing is more general — it is the idea of running computations on multiple processors simultaneously, not just two.
