Xilinx at Work - DSL Modems

Xilinx Solution Summary

Xilinx provides significant value in a DSL modem when used to interface various ASSPs together, resolving differences in their interface control signals. The functions typically performed will be in the areas of DMA control, interface controls to the buffer memory, data buffering, or the interface to the host computer. When the host computer interface is a bus standard such as PCI, Xilinx has a 32-bit, 33 MHz PCI solution available for integration into the Xilinx solution. 

The in-system programming capability of Xilinx devices enables features to be upgraded while the product is in the field, as well as speeding the time-to-market for the product.  The Spartan™XL and the Spartan™-II FPGA or XC9500XL CPLD devices are ideal candidates for this low-cost application, as well as the LogiCORE™ PCI32 core.
