To solve measurement and control problems, the processing of input data is performed typically by model-based digital signal processing (DSP) systems, which contain a representation of our knowledge about the nature and the actual circumstances of the problem at hand. If the nature or the actual circumstances change, the corresponding model should also be changed. Similarly, if the amount of kn...

In this review paper we discuss selected issues associated with the implementation of arithmetic for VLSI Digital Signal Processors. We start with a Silicon Technology Roadmap view of the next decade, in order to grasp some of the issues facing the next generation of VLSI designers, particularly associated with high performance DSP systems. We use this roadmap to open the discussion on the role...

The multiply-accumulate (MAC) unit is an addition to the ColdFire core that provides a new level of support for signal processing algorithms. This paper details the associated support functions within the instruction set. Signal processing features are discussed for potential applications in embedded systems, and examples are presented for implementing some useful algorithms.

A digital signal processing (DSP) laboratory is under development at Kettering University. The laboratory materials and procedures are designed to accommodate varied student learning styles. The implications of this learning-style based approach to undergraduate DSP laboratory development are presented, including descriptions of experimental procedures.

Multirate systems are building blocks commonly used in digital signal processing (DSP). Their function is to alter the rate of the discrete-time signals, which is achieved by adding or deleting a portion of the signal samples. Multirate systems play a central role in many areas of signal processing, such as filter bank theory and multiresolution theory. They are essential in various standard si...

A method is discussed for DNA or protein sequence comparison using a finite field fast Fourier transform, a digital signal processing technique; and statistical methods are discussed for analyzing the output of this algorithm. This method compares two sequences of length N in computing time proportional to N log N compared to N2 for methods currently used. This method makes it feasible to compa...
