Abstract
A video decoder organizes and stores pixel lines of a reference picture into first and second memory devices. The video decoder then reads portions of a pixel block from the first and second memory devices and processes such a pixel block for generating a subsequent picture. By reading from the first and second memory device with time overlap, latency is minimized for faster video decoding.
Claims30
A method of decoding video data, comprising:
- storing a first set of pixel lines of a reference picture into a first memory device and storing a second set of pixel lines of the reference picture into a second memory device;
- and
- reading a first portion of a pixel block from the first set of pixel lines in the first memory device and reading a second portion of the pixel block from the second set of pixel lines in the second memory device, for generating a subsequent picture.
An apparatus for decoding video data, comprising:
- a first memory device;
- a second memory device;
- and
- a video decoder including:
- a data processor;
- and
- a third memory device having sequences of instructions stored thereon, wherein execution of the sequences of instructions by the data processor causes the data processor to perform the steps of:
- storing a first set of pixel lines of a reference picture into a first memory device and storing a second set of pixel lines of the reference picture into a second memory device;
- and
- reading a first portion of a pixel block from the first set of pixel lines in the first memory device and reading a second portion of the pixel block from the second set of pixel lines in the second memory device, for generating a subsequent picture.
