FPGA Synthesis of Custom DSP Blocks Using Distributed Arithmetic
Design How-To 6/8/2001 Post a comment
Distributed arithmetic, coupled with memory-rich FPGA platforms, provides an efficient means of implementing certain types of DSP functions. Instructors from the niversidad Politcnica de Valencia,Spain, explain how to design FPGA-based parameterized finite-impulse-response (FIR) filters based on this branch of mathematics.
A Quadrature Demodulator Tutorial
