SPARC Full Form

SPARC stands for Scalable Processor Architecture.
SPARC is a general purpose, 32-bit integer and 32, 64, and 128-bit floating- point unit, ISA (instruction set architecture) based on RISC (reduced instruction set computer) designs built at the University of California at Berkeley.


The main goal of developing the architecture of SPARC was to optimize the compilers and effectively pipeline hardware executions. SPARC development and implementation gave uncommonly higher execution rates and shorter time-frame to market improvement plans. The SPARC “register window” structures permit an exceptional decrease in memory load/store guidelines sets.


SPARC was first formulated in mid-1987 at Sun Microsystems. SPARC has been actualized in processors used in a scope of PCs from laptops to supercomputers. SPARC International member organizations boats over a dozen different compatible microprocessors since SPARC was first declared by Sun and Fujitsu in 1986—more than any other chip family with this level of binary compatibility. Sun has made SPARC a highly-scalable open source, the non-proprietary architecture so all organizations and individuals can exploit products based on the SPARC architecture and accessible for authorizing to the microprocessor manufacturers. In 1989, the structure was transferred over to SPARC international trade-group which administrates, licenses, advances SPARC configuration, oversees SPARC trademarks and gives conformance testing.The SPARC architecture is now widely used for hardware used with UNIX-based OS, including Sun’s own Solaris systems.

The significant amendments to the design is as follows:

  • SPARC-V7: 32 bit architecture, 1986
  • SPARC-V8: 32 bit architecture, 1992
  • SPARC-V9: 64 bit architecture, 1993
  • UltraSPARC: extension of SPARC-V9, 1995

Characteristics of SPARC

  • Open Source: Sparc provides flexibility of license and opportunity to configure own solution using the SPARC architecture by any individual.
  • Performance and Economy: Disentangled and higher number of instructions sets with less transistors.
  • Scalability: The SPARC structure is adaptable, both in cost and capacity. Adaptable incorporation of cache, memory, and FPUs.
  • Compatibility: The SPARC architecture provides full compatibility from generation to generation of the structure, just as over the full scope of items depending on SPARC implementation.
  • Versatility: The SPARC architecture provides variety of commercial, technical, aerospace and military applications and so forth.
  • Object-Oriented: The object-oriented programming features is dominant in SPARC.


  • The SPARC architecture is simple and powerful.
  • The SPARC structure is advanced to meet the expected expectations of clients providing high performance on real-world applications and low Cost of Ownership
  • SPARC frameworks have typically 60%-85% more prominent per-center productivity.
  • Sun servers with the SPARC arrangement convey expanded adaptability, scalability, a higher level of accessibility.
  • SPARC-V9 structure provides multiple threads per core which decreases CPU wait time and increases CPU usage time.
  • Disadvantages

    • The SPARC architecture is not used for educational purposes rather it is used by developers and computer architects who manages the server applications and lower level programming as compared to other RISC architectures, such as MIPS and ARM.
    • AS the SPARC is an open architecture for all individuals, may misuse the product based on the SPARC architecture.
