This category holds links on open source aspects and versions of SPARC processors. SPARC is an acronym for Scalable Processor ARChitecture. It is a RISC (Reduced Instruction Set Computing) design created and licensed by Sun Microsystems, Inc. RISC work began at Sun in 1984, by Bill Joy and Dave Patterson, and the first SPARC was introduced in 1987. It is widely licensed and used.
