DSP-8682

Full-length PCI Express Card with 8 TMS320C6678 DSPs
  • Eight TI TMS320C6678 DSPs on single full-length PCI Express Card with PCIe Gen3 x8 interface to the edge connector
  • Eight TMS320C66x™ DSP Core Subsystems (C66x CorePacs) @ 1/1.25 GHz per DSP
  • 2 GB (Optional) DDR3-1333/1600 on board memory per DSP
  • Applications: – Audio and video transcoding/transrating – Media gateways and accelerator – High Performance Computing – Broadcasting Application – Automatic Optical Inspection
The DSP-8682 integrates eight Texas Instruments TMS320C6678 multi-core digital signal processors (DSPs) each with 2GB of DDR3 1333/1600MHz 64-bit DDR3 memory, the PLX® ExpressLane™ PEX8748 PCIe Gen 3 switch, a Xilinx XC3S200AN Spartan-3 FPGA, and an IDT CPS1616 Serial RapidIO Gen 2 switch to achieve the highest possible performance levels in a full-length PCIe form factor. The PEX8748 and the IDT CPS1616 interconnect x2 lanes between each DSP device. A high speed connection to the host is assured through the PEX8748 switch’s PCIe x8 Gen 3 interface for the fastest possible data transfers. A HyperLink chip-to-chip interconnect interface has been implemented enabling the on-chip navigator to transparently dispatch tasks for execution between DSP pairs.
In addition, an SGMII daisy chain between all devices is connected to a Broadcom BCM5482S providing two RJ-45 Giagabit Ethernet connections the I/O panel.
The DSP’s provide fixed- and floating-point capabilities enabling the board to perform 2,048 GMACs (Giga Multiply-Accumulation operations per second) using the embedded C66x DSP cores inside the TMS320C6678 devices.
The 64 DSP cores on the DSP-8682 make it ideal for power efficient solutions based on commercial and industrial servers needing the highest performing video processing technology on fast-to-deploy PCIe add-in cards. This raw computing power makes the DSP-8682 a perfect fit for advanced and complex video processing such as JPEG2000 for 2K/4K processing, AVC-Intra 50/100 and AVC-Ultra, deep-color pixel manipulation, HEVC/H.265 and motion-compensated temporal filtering. It is also suited for applications in many industries such as media gateways and high performance computing.
