Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).
The design of Finite Impulse Response (FIR) filters has evolved into a sophisticated discipline that balances signal-processing performance with hardware efficiency. Innovations in FIR filter design ...
In this paper, we first review in detail the basic building blocks of reconfigurable devices, essentially, the field-programmable gate arrays, then we describes a high-speed, reconfigurable Systolic ...
Previous columns have described how analog and switched-capacitors filters work and provided a real example of each. Now on to digital filters that process discrete-time digital values, rather than ...
Georgia Tech has developed a general-purpose MMIC (monolithic microwave IC) for the direct filtering and processing of microwave and millimeter-wave signals. The aim is to reduce radio power ...
Why use FIR filters, anyway? With the availability of easy-to-use IIR filters in Cypress Semiconductor’s PSoC Creator’s Filter tool, I’ve spent a lot of time over the years telling people the ways in ...
In considering the design option for DSP vs. FPGA it is helpful to compare both architectures in a FIR filter application, writes Reg Zatrepalek One of the most widely used digital signal-processing ...
Digital filters are always an interesting topic, and they are especially attractive with FPGAs. [Pabolo] has been working with them in a series of blog posts. The latest covers an 8th order FIR filter ...
