Agranat Systems Ports EmWeb Embedded Web Server to Patriot Scientific's PSC1000 Microprocessor.

SAN JOSE, Calif.--(BUSINESS WIRE)--Nov. 3, 1998--

EmWeb Technology Allows Centralized,

Web-Based Management of Embedded Systems

Patriot Scientific Corp. (OTC:PTSC), the developer of the first market-ready microprocessor for Java(TM), today announced at the Embedded Systems Conference that Agranat Systems has ported its highly regarded Web server technology directly to Patriot's PSC1000 microprocessor.

Agranat's EmWeb(TM) is the industry's leading embedded Web server and development architecture. Direct porting of the Web server software to the microprocessor eliminates the license cost and memory requirements of using a real-time operating system (RTOS), making this one of the lowest-cost embedded Web server hardware and software combination on the market today. For customers requiring an RTOS in their applications, the EmWeb software can also run on top of Wind River's VxWorks RTOS, which has also been ported to the PSC1000.

According to Aberdeen Group Senior Analyst Jim Ayube, "Aberdeen's research shows that it won't be long before embedded systems in many enterprises will simply be nodes on a network and centrally managed using a Web browser. Embedded Web servers will gradually become the preferred method to monitor, configure and control embedded systems."

"There is clearly a market demand for this type of technology," said Jim Lunney, president of Patriot Scientific. "A 1997 study by International Data Corporation forecasts that there will be 89 million non-PC devices connected to the Internet by 2001. Many of these will contain embedded Web server technology to enable them to be remotely monitored and controlled via a common Web browser. Patriot expects this technology to eventually become pervasive in consumer products as well as industrial and office devices. In working with Agranat, we are attacking this high-volume market by combining the best price/performance microprocessor with the industry's most powerful embedded Web server. We see it as a powerful alliance."

The Patriot PSC1000 microprocessor is the only true low-cost, high-performance, native Java processor. It is ideal for Internet-enabled information kiosks, cell phones, video phones, embedded Web servers, set-top boxes and a host of other new Internet appliances. The 32-bit microprocessor, based on Patriot's patented ShBoom(TM) technology, is designed to provide cost-efficient solutions for the growing number of new Java applications, as well as other traditional embedded systems markets.

"The unique performance characteristics of the PSC1000 have application in a broad range of industrial and commercial devices," said Ian Agranat, president and founder of Agranat Systems. "The EmWeb Server, combined with PSC1000-based devices, permits any authorized Web browser anyplace on the Internet to control and monitor embedded units. EmWeb and the worldwide reach of the Web can bring the power and performance of the PSC1000 to millions of Internet users."

The ported EmWeb software and PSC1000 microprocessor are available immediately from their respective companies. Patriot distributors include Real Vision in Japan, Ineltek in Germany and Austria, Pantek Technology in Taiwan, Thame Components in the U.K., Integrated Electronics in Finland, Microtronics in Southeast Asia (Singapore, Malaysia, Thailand, Philippines, Indonesia), Iridium Data in Israel and Acetronix in Korea.

Agranat Systems Inc. is a software development company specializing in embedded Web technologies for data communications, telecommunications, and other manufacturing industries seeking to provide added value and competitive advantages for their products and customers by implementing Web-based management capabilities. Organizations that have licensed EmWeb technology include Hewlett Packard, Cabletron, 3Com, Bay Networks, Lucent, Nortel, Compaq, Nokia, and many other companies.

Agranat Systems represents the embedded Web server industry on the Internet Engineering Task Force (IETF) for Web standards development and the Desktop Management Task Force (DMTF) and is a member of the World Wide Web Consortium (W3C).
