| What is SPARC?
SPARC (which stands for Scalable Processor ARChitecture) is an open set of technical specifications that any person or company can license and use to develop microprocessors and other semiconductor devices based on published industry standards. SPARC was invented in the labs of Sun Microsystems Inc., based upon pioneering research into Reduced Instruction Set Computing (RISC) at the University of California at Berkeley. The first standard product based on the SPARC architecture was produced by Sun and Fujitsu in 1986; Sun followed in 1987 with its first workstation based on a SPARC processor. In 1989, Sun Microsystems transferred ownership of the SPARC specifications to an independent, non-profit organization, SPARC International, which administers and licenses the technology and provides compliance testing and other services for its members. As an open architecture, the SPARC specifications have been refreshed with advanced technologies, evolving to SPARC Version 9. All versions of the architecture are available today. What makes SPARC "open?" While many proprietary architectures claim to be open, the truth is that adopters of a proprietary chip must aclearcase/" target="_blank" >ccept the architecture "as is." Conversely, the SPARC architecture fulfills essential elements of openness. The SPARC instruction set is published as IEEE Standard 1754-1994. SPARC specifications are available for licensing by any person or company, giving customers flexibility and freedom to design their own solution. Control of the SPARC architecture is in the hands of an independent, non-profit organization, SPARC International, whose membership is open to everyone. How much does it cost to use the architecture? All technical information about the architecture is available for free and without royalties from SPARC International's public website. Anyone is welcome to download the SPARC specifications, which provide all of the technical requirements needed to design processors and other products based on the open SPARC standard. SPARC International also offers registry services for a one-time fee of $99, which is particularly important to those companies that track the source of technology in their products. While the technical information is free, use of the SPARC trademark requires two things: First, membership in SPARC International; and second, compliance testing of the device. What are the benefits of an open architecture? Open architectures like SPARC expose the instruction set to a large community. All classes of users have fair and equal access to the technical underpinnings of the architecture. As a result of this exposure to a greater and more varied community, innovation and advancement can occur more rapidly. This is in marked contrast to proprietary architectures, whose instruction sets cannot be licensed. What are the benefits of the SPARC open architecture? The SPARC architecture has four key benefits in addition to the overarching benefit of openness. The architecture is scalable, both in price and function. It is the only open architecture that has processors that scale in price from less than $10 to more than $3,000. Functionally, SPARC processors power devices as small as set-top boxes and digital cameras, and as large as mainframe-class UNIX servers that run the world's largest businesses. Devices based on the SPARC architecture have proven performance and rank among the most powerful in the world. The SPARC architecture guarantees compatibility from generation to generation of the architecture, as well as across the full range of products based on SPARC implementations. For example, applications running on any previous generation SPARC/Solaris-based server, going back to products released in 1987, will run with enhanced performance on the newest Sun systems. The SPARC developer community has more than two million members offering over 30,000 applications, which ranks the developer community among the largest in the world. How does SPARC compare to other architectures? Customers who adopt proprietary architectures can build systems around the chips, but cannot build their own versions of the chip. This drawback prevents OEMs from differentiating their products architecturally and precludes them from optimizing the architecture for specific applications. SPARC licensees, on the other hand, have full access to the core instruction set, making it possible for them to create their own version of the chip. They are able to add their own features and extend the capabilities of the architecture, while assuring compliance and compatibility - after successfully testing - with the SPARC standard. How has SPARC been deployed? The SPARC architecture powers a variety of commercial, technical, aerospace and military applications, and can be found in data center servers, super computers, desktop and portable workstations, digital cameras, .network switches, set-top television cable boxes, and digital storage devices. Who is SPARC International? SPARC International is an independent, non-profit organization founded in 1989 to administer SPARC instruction set licenses and provide compliance-testing and other services to licensees for a fee. Today, more than 50 corporations from around the world are members. A complete list of members is available at www.sparc.org/members.html. What are the benefits of membership in SPARC International? Members benefit in several ways including: Your web page within SPARC International's web site which links to your home page. One product page of your choice with a link to your sales field for immediate purchasing. (Additional fee information for adding products available upon request). Royalty free use of the SPARC Membership and SPARC Driven logos. Continuous use of the on-line daily newsletter SPARC-Flash as often as you wish to submit articles. Exposure of your company to upwards of 1/2 million web hits per month. Public acknowledgement to your customers that your company believes in and supports the importance of SPARC International's Open Standard Architectures. Membership Categories and Cost to Join: SPARC International offers four types of membership: Executive Membership attracts companies that have a strategic interest in the SPARC architecture. Executive members hold seats on the Board of Directors and the Architecture Committee, and are eligible to vote on changes to SPARC International specifications. The annual dues for Executive Membership are $100,000 Associate Membership is open to original manufacturers of hardware and software systems. Associate members elect two representatives to the Board of Directors. The annual dues for Associate Membership are $20,000. ISV/IHV/VAR/OEM Membership is for companies interested in promoting the continued growth of the architecture. The annual dues are $1,500. Academic Membership is for colleges and universities that do not supply products or services. The annual dues are $100. |
