Abstract :
This paper examines methods for the design, implementation, and verification of pipelined adaptive filters in programmable logic. Pipelined adaptive filters can operate at far higher rates than non-pipelined types, but relaxations are required to realize these recursive structures. Design tools that automate the implementation of these filters are demonstrated, along with utilities that allow simulation of the completed system in both fixed and floating point formats. Finally, a communications channel equalization is designed and implemented
