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 1989 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 family of processors. Later, SPARC processors were used in SMP and CC-NUMA servers produced by Sun Microsystems, Solbourne and Fujitsu, among others, and designed for 64-bit operation.
SPARC International was intended to open the SPARC architecture to make a larger ecosystem for the design, which has been licensed to several manufacturers, including Texas Instruments, Atmel, Cypress Semiconductor, and Fujitsu. As a result of SPARC International, the…
