H. P. Sharangpani

H. P. Sharangpani was Intel's Numerics Architect and Project Leader for Microcode & Algorithm Development on the Pentium Processor Development Team, and co-author (with M. L. Barton) of Intel's own 1994 internal account of the Pentium floating-point division defect.

In this vault, Sharangpani & Barton 1994 is the primary document underneath the confirmed cause of the Pentium FDIV bug — the engineer who built the defective part, describing the defect's origin in the engineer's own words, rather than a secondary summarizing it.
