Xilinx Spartan-II FIR Filter Solution
Traditionally, digital signal processing (DSP) algorithms are implemented using general purpose programmable DSP chips for low-rate applications. Alternatively, special-purpose, fixed function DSP chipsets and application-specific integrated circuits (ASICs) are used for high-performance applications. Technological advancements by Xilinx in Field Programmable Gate Arrays (FPGAs) in the past 15 years have opened new paths for DSP design engineers. The most common digital building blocks, like serial peripherals, DMA controllers, PCI controllers, and synthesizable processors, are all readily realizable using a Spartan-II device. In fact, all the most basic operations performed by analog or digital electronic devices—filtering, amplification, modulation, storage, and computation—can be implemented with Spartan-II.
