SPARC SPARC
（重定向自Scalable Processor ARChitecture）
SPARC (from "scalable processor architecture") is a RISC instruction set architecture (ISA) developed by Sun Microsystems and introduced in mid-1987.
SPARC is a registered trademark of SPARC International, Inc., an organization established in **** to promote the SPARC architecture, manage SPARC trademarks, and provide conformance testing. Implementations of the original 32-bit SPARC architecture were initially designed and used in Sun's Sun-4 workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 series of processors. Later, SPARC processors were used in SMP and CC-NUMA servers produced by Sun, Solbourne and Fujitsu, among others, and designed for 64-bit operation.
