AN OPTIMISED ARCHITECTURE FOR A DOWNSAMPLING FIR FILTER |
摘要 |
<p>An apparatus for generating filtered and downsampled data comprises a calculation unit, a polyphase addition unit and a downsampling unit operable in a data decimation phase and a data preserving phase. The calculation unit is arranged to receive input data and is configured to generate a first data part during the data decimation phase and a second part during the data preserving phase. The polyphase addition unit is configured to generate a third data part in dependence on said first and second data parts and to output said third data part to the downsampling unit.</p> |
