SHARING RESOURCES IN A DIGITAL FILTER |
摘要 |
A digital filter (1) has a filter cell (4a) for generating processed data. The digital filter cell includes plurality of coefficient registers (14) which are arranged to circulate a plurality of coefficient values that correspond to a plurality of coefficients such that each of the plurality of coefficients is output once during a predetermined period. One or more data registers (11) are arranged to circulate a data value for a time which is at least as long as the predetermined period such that the data value is output each time that a different one of the plurality of coefficients is output. A circuit (12) receives each output data value and each output coefficient and generates processed data by processing each output data value with each output coefficient. |
