SPARC
SPARC is a Registered trademark by SPARC International, Inc. to indicate an open architecture of Microprocessor. Its name is the Retro-acronym of Scalable Processor ARChitecture (“architecture of adaptable processor”).
It is built on a model RISC, privileging pipeline and reduced Instruction set. This architecture supports as of 1995 the data and addresses memory in 64 bit S.
Under this generic name in fact a a whole family of microprocessors having enormously evolved/moved since the first versions developed with Berkeley in 1984 hides. The evolution of architecture is decided by SPARC International, Inc. gathering in particular Sun Microsystems, Fujitsu and Texas Instruments.
There exist three large versions of this architecture:
- SPARC V7 : appeared around 1987, architecture 32 bits
- SPARC V8: appeared around 1991, architecture 32 bits
- SPARC V9: appeared around 1994, architecture 64 bits
SPARC is an architecture whose specifications are free, which offers freedom to no matter whom to create a compatible processor.
An entirely free processor uses the Instruction set SPARC V8: the LEON. He is subjected to the license LGPL of FSF.
The SPARC V7 also gave place to the development of the processor ERC32, tolerating with radiations and used in the space field. It is for example present in the calculator of edge of the satellite of telecommunications based on a Avionique 4000 like on the Globalstar2 constellation currently under development by Thalès Alenia Space.
