MiSPO Demonstrates µITRON Support for Configurable ARC Cores at ESEC 2005

TOKYO, Japan, Embedded Systems Expo and Conference, June 29, 2005 – ARC International (LSE: ARK) and MiSPO Co., Ltd., a leading supplier of µITRON-based technology, today announced that MiSPO has ported their NORTi® Real-Time Operating System (RTOS) to ARC’s architecture and will demonstrate it to SoC designers at the eighth annual Embedded Systems Expo and Conference (ESEC) in Tokyo. The demonstration (ESEC Booth Number 6-001) will highlight MiSPO’s NORTi RTOS, µITRON 4.0-compatible real-time kernel and ITRON TCP/IP API-compatible protocol stack running on an ARC 605 configurable processor.

“ARC’s configurable cores provide cost-effective, low-power solutions that enable true differentiation at the chip level,” said Hisanori Miyazaki, president of MiSPO. “The combination of our NORTi RTOS and ARC’s processors allows embedded developers to experience the benefits of configurability within an environment that is highly optimized for the Japanese semiconductor industry.”

“Our relationship with MiSPO and the availability of µITRON technology for ARC’s customers are the latest deliverables in our promise to bring the benefits of configurable CPU technology to the Japanese semiconductor market,” said Derek Meyer, vice president of marketing for ARC International. “We expect that the availability of µITRON for our products will enhance the already strong value proposition our cores and subsystems offer developers of embedded applications in Japan.”

Availability
Various middleware solutions from MiSPO, including supporting protocols such as PPP, SNMP, POP3/SMTP and HTTP will be available soon for the ARC 600 product line. MiSPO plans to provide full NORTi and middleware support for ARC configurable processor solutions by the end of 2005.

The Configurable ARC 605 Core
The ARC 605 processor core is the world’s smallest, lowest power and most configurable 32-bit core. In a 0.13 micron process, it offers a maximum clock frequency of 250 MHz, power consumption of 0.06 mW/MHz and a die size of 0.31mm2. The 605 core is an ideal solution for a wide range of embedded control and computing functions within SoCs. The core is designed for hard real-time processing, where high speed and deterministic response are required. Furthermore, custom instruction extensions may be incorporated to achieve application performance levels unattainable with fixed architecture cores.
