Additional patent protection received for Patriot microprocessor.SAN DIEGO--(BUSINESS WIRE)--April 16, 1997-- PSC (Public Service Commission) Same as PUC. 1000 targeted for JAVA Internet Appliances Patriot Scientific Corp. (OTC OTC See: Over-the-counter. OTC See over-the-counter market (OTC). :PTSC PTSC Provisioning Technical Service Committee (Oasis) PTSC Pentagon Telecommunications Service Center PTSC Parent Teacher Student Conference ) Wednesday announced that it has received its fourth issued U.S. patent on the PSC1000 microprocessor technology. The new patent includes multiple claims and is the fourth issuance from a large number of patent applications that are still pending. The claims in this patent provide significant protection for the heirarchical memory implementation of stacks for microprocessors. The PSC1000 keeps the top stack elements in registers for extremely fast access; deeper stack elements are in on-chip RAM for fast access, and the deepest elements are in external memory. Because the top elements are the most frequently used, making them available sooner improves processing speed See MHz. . Patriot also announced Wednesday that it is developing a product aimed at the Java Internet appliance market. The company is working closely with another firm in the development of a specific product utilizing the PSC1000 as an integral part of the system. "Patriot's No. 1 priority is to take advantage of the explosive Java-powered Internet appliance market that is developing," said Derek Best, Patriot's vice president of marketing. "Sun Microsystems Sun Microsystems, Inc. (NASDAQ: JAVA[3]) is an American vendor of computers, computer components, computer software, and information-technology services, founded on 24 February 1982. , IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) , Oracle and others are making significant investments in Java as the platform of choice for the next generation information appliances, such as Internet set-top boxes, network computers, Internet televisions, cellular phones and a host of other Internet applications. "The PSC1000 runs Java applications significantly faster and with lower power consumption than existing microprocessors," Best said. "The Patriot processor does not require software interpreters or compilers needed by existing microprocessors, because the PSC 1000 can run Java byte codes directly. We are now able to download Java applications and run them faster than chips with general purpose processors." The company's strategy is to assist in the development of specific products utilizing the PSC1000, licensing the core technology and selected partnering agreements. Patriot is now working with developers to create specific tool sets for designers and software developers. Patriot's marketing efforts continue to accelerate with the firm now working with an ever-growing number of major firms. The company recently added representatives in Scandinavia, the Netherlands and in the Midwest United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. . The ShBoom-architecture PSC-series 32-bit microprocessors are the first to combine the best features of RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. and zero-operand stack architectures. Unlike other RISC chips, the architecture uses a computation stack that allows instructions to be one byte in length instead of four. This reduces program size and reduces the memory bandwidth Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of the commonly used required to feed instructions to the processor. It also provides a significant advantage for stack-based software or hardware architectures like the Java virtual machine A Java interpreter. The Java Virtual Machine (JVM) is software that converts the Java intermediate language (bytecode) into machine language and executes it. The original JVM came from the JavaSoft division of Sun. since it maps very closely to the native instructions of the architecture. The PSC-series 32 bit RISC processors are based on Patriot's patented and patent-pending architecture. Patriot is also engaged designing and manufacturing a high-performance digital communication product line and its radar and antenna technology.
