To-be-filtered data providing apparatus

The invention discloses a to-be-filtered data providing apparatus. According to the to-be-filtered data providing apparatus in the invention, a to-be-filtered data locality principle is fully utilized and a phenomenon that to-be-filtered data are repeatedly loaded does not occur. Moreover, every time a memory is accessed, BS results are obtained, so that the access number of the memory is reduced; therefore, an effect that multi-time calculation is carried out by one-time reading is realized; and thus power consumption of the whole design is reduced.
