Abstract
The invention provides a filtering device with hierarchical structure making it possible to carry out finite impulse response and infinite impulse response linear filtering functions and which can be combined with one or more devices of the same type. The device includes at least one first and one second filtering module having means for carrying out filtering functions with N configurable coefficients. A first subset of the N coefficients of a module is configured to carry out nonrecursive filtering functions, a second subset of the coefficients configured to carry out recursive filtering functions, one or more feedback loops able to be activated per module, at least one result sample of the filtering being generated at each clock cycle. The invention also provides a reconfigurable filtering device using at least two filtering devices with the hierarchical structure.
