FWR Toolbox 1.0

The FWR Toolbox is a MATLAB toolbox used to analysis the Finite Word Length ed¬TCdeects of linear time-invariant digital filters/controllers implementations.When digital d¬TCdalter/controller are implemented in computing machines (micro-controller, DSP, FPGA, etc.) with d¬TCdanite precision, a degradation occurs. It comes from:d-deD? the addition of roundod¬TCde noise after each arithmetic operations,d-deD? the rounding of the embedded parameters.The FWR Toolbox provides a general description of any possible realization (direct form, state-space, d?DL or shift operator, observer-state-feedback, cascad decomposition, etc...) in a form that allows a straightforward analysis of the FWL ed¬TCdeects. Several tools are provided to compute open-loop/closed-loop sensitivity, stability related measure, roundod¬TCde noise gain, ..., and to d¬TCdand optimal realizations, according to these criteria. It is also possible to generate d¬TCdaxed-point code (C code, VHDL, ...).web site : http://fwrtoolbox.gforge.inria.fr/
