The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
He noted that "very smart people" had to go down the "dead ends" of mechanical computers and decimal computing before reaching a scalable solution—namely, the electronic, binary computer with a von Neumann architecture. The book also covers more recent developments, including topics like floating point math, operating systems, and ASCII.
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The SAP architecture serves as an example in Digital Computer Electronics for building and analyzing complex logical systems with digital electronics. Digital Computer Electronics successively develops three versions of this computer, designated as SAP-1, SAP-2, and SAP-3. Each of the last two build upon the immediate previous version by adding ...
Glenford Myers (born December 12, 1946) is an American computer scientist, entrepreneur, and author.He founded two successful high-tech companies (RadiSys and IP Fabrics), authored eight textbooks in the computer sciences, and made important contributions in microprocessor architecture.
The result was published in 1964 in a double issue of the IBM Systems Journal, [8] thereafter known as the "grey book" or "grey manual". The book was used in a course on computer systems design at the IBM Systems Research Institute. [8] In 1965, Sussenguth joined the IBM Advanced Computer Systems project (ACS-1) to work on high performance ...
Flynn proposed Flynn's taxonomy, a method of classifying parallel digital computers, in 1966. [3]In the early 1970s, he was the founding chairman of IEEE Computer Society's Technical Committee on Computer Architecture (TCCA) [4] and Association for Computing Machinery's Special Interest Group on Computer Architecture, ACM SIGARCH (initially SICARCH).
