Palmchip Obtains Patent for Connecting IP Blocks Within a SoC Design

8/11/2003 - Palmchip Corporation, a pioneer in semiconductor IP and system-on-chip technology, announced that the US Patent and Trademark Office ( has awarded the company a key patent for the company’s technology facilitating the easy connection of IP blocks within a system on chip design. The patent (US Pat. No. 6,601,126), titled Chip-core Framework for Systems-On- a-Chip, will protect the company’s technology for building system on chips using a unidirectional bus structure enabling point-to-point connectivity for internal SoC IP cores. This technology was initially introduced to the chip design community through the company’s CoreFrame® SoC architecture.

The CoreFrame SoC architecture is used in Palmchip’s two SoC platform products, PalmPakTM and the flagship AcurXTM platform. Both platforms are configurable and are tested, pre-verified and silicon proven.

"This favorable decision from the U.S. Patent and Trademark Office represents a significant milestone in our company's history," said Jauher Zaidi, President and CEO of Palmchip Corporation. "The granting of this patent validates our SoC technology leadership and reflects our history of innovation in system on chip platform design in addition to protecting our intellectual property."

"We believe that this patent grant could have a wide-ranging impact on those companies who have created SoC devices or marketed SoC platforms using unidirectional busses as a method of assembling separate IP blocks within a design," said Jim Venable, vice president of Palmchip. "It is our intention to aggressively protect our intellectual property by making the technology available under license to those companies wishing to use it."
