Abstract:
An image processing system used to convert a plurality of data from a first sample rate to a second sample rate, the first and second sample rates being associate to a clock signal, the image processing system comprising:a data control buffer;a coefficient control buffer;a processor that selects a predetermined number of data from the plurality of data using the data control buffer, the predetermined number of data having a first sample rate;a phase filter that is indexed using the coefficient control buffer, the phase filter having a plurality of phases;a sub-phase filter formed from a predetermined number of phases, the phases being selected from the indexed phase filter, the predetermined number of phases being the same number as the predetermined number of data;the processor uses the sub-phase filter to operate on the predetermined number of data using the sub-phase filter to form a plurality of processed data; andthe processor selects a predetermined number of the plurality of processed data in response to a predetermined number of clock signals, the selected predetermined number of the plurality of processed data having the second sample rate.
