SAN DIEGO, May 7, 2002 -- PTSC (Patriot Scientific Corp.) (OTCBB: PTSC- news) announced today that the Company is completing its development of an Advanced High-Performance Bus interface implemented as an AHB Wrapper. Recent statistics published in the 2002 Semiconductor IP Trends demonstrate the deep penetration of ARM® processors in today's electronic products. The PTSC IGNITE™ AHB Wrapper was developed to enable direct interoperability between the IGNITE processor and ARM in a co-processor system architecture, as well as with the ARM peripherals and development tool chain.
"This very competitive marketplace is continually demanding additional functionality from their embedded processors," stated Patrick Nunally, PTSC's Chief Technical Officer. "As products evolve, additional features are added and more processing power is required. The addition of an IGNITE co-processor with the Advanced High-Performance Bus interface is an easier, faster and far less expensive answer to the need for additional processing performance without encountering the complexity and expense of replacing the main processor. The purpose here is to leverage the massive installed base of ARM and to give ARM developers an option of adding only about 5% to the size and power consumption of the ARM9 while increasing its processing capability by nearly 200%," detailed Dr. Nunally.
"This is a very simple solution that will dramatically scale the performance of the entire ARM processor family. Most importantly, the IGNITE AHB Wrapper allows ARM users to continue to employ their existing embedded debugging tool chain to the IGNITE specific application code," Dr. Nunally added.
Joey Maitra, the Company's Vice President of Engineering explained that after discussions with a number of electronics companies on the issue of additional performance requirements, "It was clear that they were concerned about the difficulty and expense of replacing the present processor, yet they were aware that additional processing performance is becoming mandatory. With the development of the IGNITE AHB Wrapper, the architects of those products now have an inexpensive and relatively straightforward solution to the problem of existing ARM processors reaching their maximum performance. The IGNITE processor has the ability to run in single cycle memory access mode. This eliminates the need for a cache controller. It can use its indigenous instructions, executing out of its private memory, to move and operate on data shared between the ARM and the IGNITE processors. With the addition of the IGNITE, product developers using ARM processors now have significant new options in their product roadmaps," concluded Mr. Maitra.
"We believe IGNITE with its AHB interface will be a genuine breakthrough in the delivery of more processor performance without the significant additional cost. This is a particularly important advance in a marketplace where consumers are not anticipating increasing prices for electronic devices, but they do continually expect more advanced features," concluded Dr. Nunally.
