Before we show how to optimize a FIR filter, let's review the basics of DSP architectures. (If you are already familiar with these basics, you can skip ahead to the page 2. To learn more about the ...
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 ...
Digital signal processing is ubiquitous in modern electronic systems, from MP3 players to digital cameras to wireless handsets. One of the mainstays of a DSP designer’s tool box is the FIR ...
Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...
The LMS adaptive filter is the main functional block in high channel-density line echo cancellers for VOIP. In this paper, we describe an LMS adaptive FIR filter IP and estimate its performance when ...
This article shows how to write optimized FIR filter code for a DSP, using the Texas Instruments C55x architecture as an example. Today's DSP architectures are made specifically to maximize throughput ...
