Peter Michael Kogge is an American computer engineer and IBM Fellow.

Background

Kogge has been at the forefront of several innovations that have shaped the computing industry over the past three decades. While working on his PhD at

Stanford Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California. The campus occupies , among the largest in the United States, and enrolls over 17,000 students. Stanford is considere ...

in the 1970s, Kogge invented what is still today considered the fastest way of adding numbers in a computer, the

Kogge–Stone Adder In computing, the Kogge–Stone adder (KSA or KS) is a parallel prefix form carry look-ahead adder. Other parallel prefix adders (PPA) include the '' Sklansky adder'' (SA), ''Brent–Kung adder'' (BKA), the '' Han–Carlson adder'' (HCA), the ...

and other companies. After receiving his degree, Kogge joined the computer engineering team at IBM. During his time there, he was a co-inventor on over three dozen patents. His design of the Space Shuttle I/O processor at IBM was one of the first multithreaded computers, and the first to fly in space.

Contributions

Peter was the author of the first textbook on pipelining, a now ubiquitous technique for executing multiple instructions in a computer in parallel. At IBM, Kogge was also the inventor of the world's first

multi-core processor A multi-core processor is a microprocessor on a single integrated circuit with two or more separate processing units, called cores, each of which reads and executes program instructions. The instructions are ordinary CPU instructions (such a ...
