Main Features
 

• PCI Express (PCIe) form-factor DSP farm with 2x Gigabit Ethernet ports and CT bus
• Flexible and scalable modular design supporting up to 8 TI C64x DSPs on board
• Built-in diagnostics, providing easier troubleshooting and better application control

The SURF Engine PCIe (a.k.a. SURFExpress PCIe)  board is a RoHS-compliant single-lane, half-length, full-height PCI Express form-factor DSP farm with multimedia processing capabilities. Providing two Gigabit Ethernet ports and a CT bus for additional TDM interfaces, the PCIe board is designed to meet the requirements of a variety of high-capacity multimedia applications.

SURF’s PCIe boards support the SurfDocker™ modular plug-in, which carries up to four pairs of mixed types of DSPs and supports a variety of configurations to meet the application developer’s requirements. This paradigm allows varying types of DSPs to be assembled on a single PCI Express carrier, including TI’s C64x generation or any new C64 family member that is released to market. Up to four SurfDocker modules can be plugged into a single PCIe board, totaling up to 8 DSPs per board.

Architecture

• Single lane PCI Express form factor
• Configurable interfaces to each DSP based on DSP type, including Gbit Ethernet and PCI Express
• 2 x 1000Base-T Ethernet interface (RJ-45)
• H.100 connector
• PowerPC 405 implemented within the Interface FPGA for board management
• Hosts up to eight DSPs using 1-4 SurfDocker plug-in modules, with two DSPs on each module (i.e., flexible support for 2, 4, 6 or 8 DSPs)
• Supports different types of DSPs on the same PCIe board, using different SurfDocker plug-in modules
• Features shared memory architecture that enables superior performance when heavy intra-DSP communication is required
• All data and controls are passed to the DSPs via Surf’s proprietary high-speed interface
• Supports single IP for entire board or individual DSP IP, for maximum resource management flexibility
