Embedded Digital Signal Processing Systems
With continuing progress in VLSI and ASIC technologies, digital signal processing (DSP) algorithms have continued to find great use in increasingly wide application areas. DSP has gained popularity also in embedded systems although these systems set challenging constraints for implementations. Embedded systems contain limited resources, thus embedded DSP systems must balance tradeoffs between t...
متن کاملWordlength optimization for linear digital signal processing
This paper presents an approach to the wordlength allocation and optimization problem for linear digital signal processing systems implemented as custom parallel processing units. Two techniques are proposed, one which guarantees an optimum set of wordlengths for each internal variable, and one which is a heuristic approach. Both techniques allow the user to tradeoff implementation area for ari...
متن کاملTransients in reconfigurable digital signal processing systems
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...
متن کاملQuantization of VLSI digital signal processing systems
Digital systems have finite precision, which imposes a maximum bound on the accuracy of the results of the computed mathematical operations. The so-called quantization process, also wordlength optimization, aims at finding cost-efficient hardware architectures that comply with a given maximum accuracy loss. Floating-point arithmetic is commonly used to perform scientific computations because it...
متن کاملRapid Prototyping of Digital Signal Processing Systems
The paper describes GRAPE-II (Graphical RApid Prototyping Environment), an advanced system level development environment for the specification, compilation, debugging, simulation and emulation of Digital Signal Processing (DSP) applications. GRAPE-II supports the real-time emulation of synchronous multirate applications on heterogeneous target platforms, consisting of multiple TMS320C40 process...
