SAN JOSE, Calif.--(BUSINESS WIRE)--March 12, 2001--Palmchip Corporation, a leader in SOC (system-on-chip) development platforms that feature popular embedded processor interfaces (for single-processor and multi-processor designs), today announced an MP3 SOC hardware platform featuring a configurable 32-bit RISC/DSP processor licensed from ARC Cores, Inc., a subsidiary of ARC International plc (LSE:ARK).

Palmchip and ARC will jointly market the highly integrated SOC platform solution for portable audio applications, delivered as RTL source code with models and test benches. International Data Corp. predicts the MP3 device market in the United States will grow from the estimated 1.3 million units shipped in 2000 to 6.7 million in 2003. Low power and data compression requirements make it an ideal target market for embedded solutions. The combination of ARC's processor and MP3 software with Palmchip's integration architecture is well suited for low-power audio devices.

The PALM-FC-6710 is an SOC hardware platform with support for MMC (MultiMediaCard) devices, audio input and output sources, and serial interfaces, including UART and USB. It includes DMA support for peripheral interfaces to buffer memory for reduced firmware requirements, and power management for low-power operation. It integrates ARC's RISC processor with 8KB of CPU SRAM. The memory controller supports up to 4MB of external memory or memory-mapped ports. A second UART provides a debug communication port. As Palmchip's PalmPak(TM) platform features pre-verified and pre-integrated IP, the SOC development time, compared with traditional cell-based methods, can be reduced by up to four months.

``Adding ARC's processor to an application-targeted PalmPak(TM) SOC development platform provides designers with a highly integrated and flexible solution for portable audio device applications,'' said Melissa Jones, vice president of marketing, Palmchip Corporation. ``Our hardware platform allows the customer to select software from a source of their choice and move quickly into silicon.'' Jones added, ``An important advantage to a platform-based design with a configurable processor is that designers will be able to comply easily with changing requirements in the market, such as products specifications that evolve within the Secure Digital Music Initiative.''

``Palmchip offers a highly competitive plug-and-play SOC solution,'' said Jim Turley, senior vice president of technology, ARC. ``Our partnership with Palmchip demonstrates our continued commitment to developing strategic alliances with innovative companies so we can provide our customers with a broad range of leading-edge SOC solutions.''

Palmchip's platforms, including FlexiSOC(TM) designs, are based on Palmchip's CoreFrame® integration architecture. The platforms contain the peripheral functions required for a basic SOC design, including system and watchdog timers, programmable I/O, and interrupt and memory controllers.
