  • Memory access ordering for a transformation
    Patent number: 10412400
    Abstract: An apparatus generally having a plurality of memories and a first circuit is disclosed. The memories may be configured to store a plurality of first data points. The first data points generally form a two-dimensional block. The first data points may be arranged among the memories such that a load cycle from the memories accesses a rectangular region of the two-dimensional block. The load cycle generally comprises a plurality of read cycles, a different one of the read cycles corresponding to each one of the memories. The first circuit may be configured to (i) receive the first data points as read from the memories and (ii) generate a plurality of second data points by a video codec transformation of the first data points between a spatial domain and a frequency domain.
