SCALD

Last updated

The structured computer-aided logic design (SCALD) software was a computer aided design system developed for building the S-1 computer. It used the Stanford University Drawing System (SUDS), and it was developed by Thomas M. McWilliams and Lawrence Curtis Widdoes, Jr. The work led to the start of the Valid Logic Systems company (briefly known as SCALD Corporation) in 1981, which was purchased by Cadence Design in 1991.

McWilliams and Widdoes won the W. Wallace McDowell Award in 1984 for the SCALD methodology. [1]

The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers. Before the 20th century, most calculations were done by humans.

Motorola 6800 8-bit microprocessor

The 6800 is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.

Tony Hoare British computer scientist

Sir Charles Antony Richard Hoare is a British computer scientist who has made foundational contributions to programming languages, algorithms, operating systems, formal verification, and concurrent computing. His work earned him the Turing Award, usually regarded as the highest distinction in computer science, in 1980.

John Backus American computer scientist

John Warner Backus was an American computer scientist. He directed the team that invented and implemented FORTRAN, the first widely used high-level programming language, and was the inventor of the Backus–Naur form (BNF), a widely used notation to define formal language syntax. He later did research into the function-level programming paradigm, presenting his findings in his influential 1977 Turing Award lecture "Can Programming Be Liberated from the von Neumann Style?"

Federico Faggin Italian-American physicist, engineer, inventor and entrepreneur

Federico Faggin is an Italian physicist, engineer, inventor and entrepreneur. He is best known for designing the first commercial microprocessor, the Intel 4004. He led the 4004 (MCS-4) project and the design group during the first five years of Intel's microprocessor effort. Faggin also created, while working at Fairchild Semiconductor in 1968, the self-aligned MOS (metal–oxide–semiconductor) silicon-gate technology (SGT), which made possible MOS semiconductor memory chips, CCD image sensors, and the microprocessor. After the 4004, he led development of the Intel 8008 and 8080, using his SGT methodology for random logic chip design, which was essential to the creation of early Intel microprocessors. He was co-founder and CEO of Zilog, the first company solely dedicated to microprocessors, and led the development of the Zilog Z80 and Z8 processors. He was later the co-founder and CEO of Cygnet Technologies, and then Synaptics.

The W. Wallace McDowell Award is awarded by the IEEE Computer Society for outstanding theoretical, design, educational, practical, or related innovative contributions that fall within the scope of Computer Society interest. This is the highest technical award made solely by the IEEE Computer Society where selection of the awardee is based on the "highest level of technical accomplishment and achievement". The IEEE Computer Society is "dedicated to advancing the theory, practice, and application of computer and information processing technology." Another award considered to be the "most prestigious technical award in computing" is the A. M. Turing Award awarded by Association for Computing Machinery (ACM). This is popularly referred to as the "computer science's equivalent of the Nobel Prize". The W. Wallace McDowell Award is sometimes popularly referred to as the "IT Nobel".
