  • Publication number: 20200020384
    Abstract: In one form, a memory controller includes a command queue, an arbiter, a refresh logic circuit, and a final arbiter. The command queue receives and stores memory access requests for a memory. The arbiter selectively picks accesses from the command queue according to a first type of accesses and a second type of accesses. The first type of accesses and the second type of accesses correspond to different page statuses of corresponding memory accesses in the memory. The refresh logic circuit generates a refresh command to a bank of the memory and provides a priority indicator with the refresh command whose value is set according to a number of pending refreshes. The final arbiter selectively orders the refresh command with respect to memory access requests of the first type accesses and the second type accesses based on the priority indicator.

  • Publication number: 20200007880
    Abstract: Processing circuitry decodes prediction information of a block from a coded video bitstream. The block is a non-square block and the prediction information of the block is indicative of a wide angle intra prediction mode in a specific number of wide angle intra prediction modes with angles that are outside a range of directional modes from a bottom-left diagonal mode to a top-right diagonal mode for a square block. The wide angle intra prediction modes are in a first set of intra prediction modes associated with the block. The directional modes are in a second set of intra prediction modes associated with the square block. The specific number of the wide angle intra prediction modes is a function of an aspect ratio of the block. Further, the processing circuitry reconstructs at least one sample of the block according to the wide angle intra prediction mode.
