Charles E. Leiserson

American computer scientist, co-author with H.T. Kung of "Systolic Arrays (for VLSI)" (Sparse Matrix Proceedings 1978, SIAM, 1979, pp. 256-282) — the paper Kung's own 1982 article cites as reference [5] and credits as the origin of the systolic-array concept it explains. Widely known outside this vault's scope as a longtime MIT computer science professor and as a co-author of the standard algorithms textbook Introduction to Algorithms (CLRS).

Matters to this vault as the co-inventor half of the systolic-array origin story: every claim-note in the vault's systolic-array/TPU/cardiac- metaphor cluster traces back to the 1978 Kung–Leiserson paper as its starting point, even though the cluster's direct sourcing so far has been to Kung's later, sole-authored 1982 explanation of the idea. The 1978/79 Kung–Leiserson paper itself is not yet read directly in this vault — a DTIC-hosted copy (ADA066060) returned HTTP 403 in the 2026-08-12 session — and is the most likely home of the original phrasing behind the popular but misattributed "processor... pumps data in and out" quote (see myth-kung-1982-processor-pumps-quote).
