This brief video demonstrates building an embedded custom process on a Xilinx Spartan FPGA.

At IBC2009, TeamCast introduced its newest DTV and mobile TV modules, integrating the latest Xilinx field-programmable gate arrays (FPGAs). Since 2003, TeamCast has deployed Xilinx Virtex and Spartan FPGAs in all of its OEM modulation products, as well as in the GFX-0300 gap filler and RPX-1000 demodulator measurement receiving probe.

TeamCast credits key features of Xilinx chips with enabling competitive flexibility and price performance, including:

• The ability to embed processing and programmable logic in a single FPGA;
• Abundant programmable logic with shift register lookup table and distributed memory;
• Digital signal-processing and embedded memory blocks;
• Preconfigured PLL interface that generates all the clocks needed for each modulation standard;
• PowerPC processor embedded in Virtex FPGAs;
• Xilinx design system software platform, ISE Design Suite and CORE Generator, featuring optimized FFT and FIR cores; and
• Xilinx FPGA reprogrammability via device download.

TeamCast uses Xilinx FPGAs for DTV and mobile TV modulation, output signal processing for amplifier nonlinear and linear precorrection, echo cancellation and signal shaping.
