Abstract:
1. An apparatus for providing a uniform data signal to an elastic store, the apparatus comprising: first and second pointer signals; a pointer encoder receiving the first and second pointer signals and providing a composite pointer signal having a period and a magnitude; a first filter receiving the composite pointer signal, the first filter configured and arranged to filter the magnitude of the composite pointer signal and to provide a first filtered signal; a second filter receiving the composite pointer signal, the second filter configured and arranged to filter the period of the composite pointer signal and to provide a second filtered signal; a bit leak rate calculator receiving the first and second filtered signals, the bit leak rate calculator configured and arranged to provide a bit leak rate value; an offset generator receiving the bit leak rate value, the offset generator configured and arranged to provide a center offset value; an elastic store having a plurality of storage locations at least a portion of which store data, the elastic store configured and arranged to provide an elastic store fill value indicative of the portion of storage locations containing data, the elastic store also configured and arranged to provide an elastic store center value indicative of the median storage location; a prefilter receiving a system clock signal, the elastic store fill value, the elastic store center value, and the center offset value, the prefilter configured and arranged to provide a uniform read enable signal to the elastic store, wherein the elastic store provides as an output a plurality of more-uniformly-gapped data.
