Scratchpad may refer to: A pad of paper, such as a notebook , for preliminary notes, sketches, or writings Scratchpad memory , also known as scratchpad, scratchpad RAM or local store, is a high-speed internal memory used for temporary storage of calculations, data, and other work in progress
Two computer algebra systems named Scratchpad were developed by IBM. The first one was started in 1965 by James Griesmer [ 2 ] at the request of Ralph Gomory , and written in Fortran . [ 3 ] The development of this software was stopped before any public release.
Scratchpad also was used in later Fermi GPU (GeForce 400 series). [6] Ageia's PhysX chip includes a scratchpad RAM in a manner similar to the Cell; the theory of this specific physics processing unit is that a cache hierarchy is of less use than software managed physics and collision calculations. These memories are also banked and a switch ...
This free software had an earlier incarnation, Macsyma. Developed by Massachusetts Institute of Technology in the 1960s, it was maintained by William Schelter from 1982 to 2001. In 1998, Schelter obtained permission to release Maxima as open-source software under the GNU General Public license and the source code was released later that year ...

"Free and open-source software" (FOSS) is an umbrella term for software that is considered free software and/or open-source software. [1] The precise definition of the terms "free software" and "open-source software" applies them to any software distributed under terms that allow users to use, modify, and redistribute said software in any manner they see fit, without requiring that they pay ...
The Fairchild F8 is an 8-bit microprocessor system from Fairchild Semiconductor, announced in 1974 and shipped in 1975. [1] [2] The original processor family includes four main 40-pin integrated circuits (ICs); the 3850 CPU which contains the arithmetic logic unit and a scratchpad, the 3851 Program Storage Unit (PSU) which contains 1 KB of program ROM and handles instruction decoding, and the ...
