TEXAS INSTRUMENTS INTRODUCES INDUSTRY'S MOST ADVANCED RISC MICROPROCESSOR

 TEXAS INSTRUMENTS INTRODUCES
 INDUSTRY'S MOST ADVANCED RISC MICROPROCESSOR
 HOUSTON, May 7 /PRNewswire/ -- The industry's most advanced RISC (reduced instruction set computing) microprocessor for the next generation of SPARC workstations was unveiled today by Texas Instruments (TI), (NYSE: TXN).
 In making the announcement, the company said the chip has the design strength and upgrade flexibility to accommodate business computing into the next century.
 SuperSPARC(TM) consists of 3.1 million transistors on a single chip. It is the first single-chip SPARC(TM) microprocessor to have complete built-in multiprocessing. SuperSPARC multiprocessing allows system vendors to expand from one to many microprocessors in the same system to increase performance. At an operating speed of 40 megahertz, it delivers up to 150 million instructions per second (MIPS), three times the performance of PC microprocessors.
 SuperSPARC marks the first in a series of products jointly developed by TI and Sun Microsystems Computer Corp. (SMCC). The two companies announced today they are also working together on SPARC chip designs for low-cost desktop projects, as well as very high-performance, next-generation extensions of SuperSPARC.
 SuperSPARC speeds performance of the nearly 5,000 SPARC(TM) software applications such as Lotus(R) 1-2-3(R) and Word Perfect(R) due to an advanced superscalar architecture. Using the advanced chip, the performance of financial management, publishing, engineering, manufacturing and other business applications can be increased by up to three times of performance achieved with conventional RISC designs.
 Engineering has reduced the chip count to a single chip in SuperSPARC, compared to 12 chips in SMCC's SPARCstation(TM) 2, while increasing the chip's performance significantly. With fewer components, systems design and manufacture can be simplified, with the anticipated benefit of lower systems cost.
 SPARC, an open standard, is the most widely accepted RISC architecture, accounting for more than 63.1 percent of all RISC workstations and workstation/servers shipped in 1991, according to industry market researchers at International Data Corporation.
 SuperSPARC -- which already has received endorsements from ICL, Solbourne, Xerox, SunPro, SunSoft, Lotus Development Corporation and Frame Technology -- is specially designed for a wide range of uses, from stand-alone desktop applications to superservers in computer networks. Several members of SPARC International are expected to announce SuperSPARC-based workstations this year.
 TI is in volume production of SuperSPARC now and taking orders from key SPARC International Executive Members. TI will begin taking orders from non-executive members during the third quarter of 1992, with delivery in the fourth quarter.
 SuperSPARC is the result of a cooperative development agreement signed by TI and Sun in late 1988 to advance SPARC state-of-the-art. TI and Sun employees worked on teams at sites in Houston, Dallas and California throughout all phases of this program.
