Hifn Powers Next Generation FlowThrough Security Architecture with ARC Internationalís Latest SoC Development Platform

10/24/2002 - ARC International, a world leader in configurable System-on-Chip (SoC) platform technologies, announced the licensing of its user-customizable SoC development platform to HifnTM, a leading supplier of advanced compression, encryption and classification technologies. ARCís latest generation 32-bit ARCtangent-A5 RISC/DSP microprocessor core and software-based unified development tool chain were selected for the design of Hifnís next generation HIPP III (Hifn Intelligent Packet Processing) family of security processors utilizing the innovative FlowThrough architecture.

Hifnís new breakthrough architecture will continue the companyís mission to make high-speed next generation networks operate more securely. The ARCtangent core provides the essential blend of programmability and performance required for the most demanding and advanced applications. Programmability is the key to supporting the requirements of todayís security landscape while providing the flexibility to address the features of tomorrowís divergent markets. Performance is a necessary complement since security technology must scale to support the needs of customers as they migrate to ever-higher performance levels.

Hifnís new breed of HIPP III security processors incorporating FlowThrough technology must handle not only cryptographic acceleration and packet processing, but also protocol stack functionality for encryption and authentication. "The ARCtangent cores offer the customization and flexibility we need to utilize multiple instances with optimized size and performance for each specific task," said John Metzger, Hifnís vice president of engineering.

"By utilizing ARCís tightly integrated IP building blocks optimized for embedded communications devices and a process-independent SoC development platform, Hifn will be able to reduce its time to market with a highly differentiated and powerful security processor design," said Mike Gulett, president and chief executive of ARC International. "In particular, Hifnís design team can focus primarily on optimizing the specifications for network security designs instead of allocating precious time and budget on IP interoperability risks, multiple test and verification tasks, and process-dependent issues."

The ARCtangent user-customizable 32-bit RISC/DSP microprocessor platform allows developers to synthesize and configure robust ASIC, ASSP, system-on-chip (SoC) and FPGA designs. Developers can readily customize their ARCtangent-based designs by optionally adding instructions, registers, DSP components, instruction and data caches, and peripherals to the base-case specifications of the RISC CPU by using an easy-to-use graphical user interface (GUI) included in the platformís integrated ARChitectTM processor configuration tool. ARChitect allows developers to make changes to the system design at later stages in the design cycle to accommodate changing specifications or to differentiate features.
