FPGA & DSP

The DSP+FPGA high-speed signal acquisition and processing board is independently developed by ZKey, including TI DSP TMS320C6678 and Xilinx FPGA K7 XC7VK690T. The communication between FPGA and DSP is achieved by high-speed 4-lane 5Gbps SRIO. This system can be used in software radio system, baseband signal processing, wireless simulation platform, high-speed image acquisition and processing, etc.

• DSP Chip Information

TMS320CC6678 is a new generation of DSP chip launched by TI. Its core, peripheral interface and internal interconnection capabilities have been greatly improved compared to C64x series DSPs. First of all, it has eight processor cores C66x, and the C66x core has both 320GMAC fixed-point and 160GFLOP floating-point processing capabilities. Then, its peripherals integrate a new generation of high-speed interfaces such as SRIO2.1, PCIe2.0 and HyperLink. In addition, the internal interconnection also uses the new TeraNet switch interconnection technology, which has a very high rate.
