SURFRIDER-812 / PTMC™
Overview
Cost-effective Processing in Powerful Yet Flexible Computing Environment
The SurfRider-812/PTMC is a fully integrated RoHS-compliant PMC/PTMC DSP resource board providing multimedia processing capabilities. Featuring cost-effective processing power and Surf's patent-pending Open Framework design, which allows seamless integration of user-defined and proprietary algorithms, the SurfRider-812/PTMC meets IMS requirements and is the ideal choice for development of a wide range of carrier-grade telecom applications. It is field-proven, having already been implemented by a number of Tier-1 TEMs.
The SurfRider-812/PTMC DSP resource board provides a powerful yet flexible computing environment for developers of embedded applications. The board is supplied with multiple drivers and a variety of interfaces. Developers can choose to work with the DSP BIOS supplied by Texas Instruments, or leverage the operating system supplied by Surf to gain streaming support and greatly reduce development time.
For developers of telecom infrastructure equipment, the SurfRider-812/PTMC integrates with SurfWare-Media™, Surf's telecom-ready media processing software that allows proprietary applications to be embedded directly into the DSP framework.
The SurfRider-812/PTMC DSP resource board is truly a PMC form-factor board. All DSPs are located on the top side for efficient cooling. It includes complete on-board power generation, using strictly 5V and 3.3V levels. The board is fully PMC- and PTMC-compliant, compatible with a wide range of host platforms, and integrates with PCI, cPCI, and ATCA carrier boards. In addition to telephony applications, the SurfRider/PTMC DSP resource board can serve as a flexible, high-capacity, programmable platform for other processing-intense applications such as video processing, VoIP, cryptography, and medical imaging.
