Abstract
A VLC data transfer interface is presented that allows digital data to be packed and assembled according to a format selectable from a number of formats while the data is being transferred to a desired destination.
Claims21
A memory interface comprising:
- a buffer comprising a plurality of sections, wherein each section of said plurality of sections is associated with a respective category of data;
- a memory;
- and
- a data transfer logic coupled to said buffer and said memory, wherein said data transfer logic is further operable to transfer data from said buffer to said memory, wherein said data transfer logic is further operable to access said data from a first set of said plurality of sections responsive to a selection of a first format, and wherein said data transfer logic is further operable to access said data from a second set of said plurality of sections responsive to a selection of a second format.
1 more element
A system comprising:
- a processor;
- and
- a graphics controller coupled to said processor and comprising a memory interface, said memory interface comprising:
- a buffer comprising a plurality of sections, wherein each section of said plurality of sections is associated with a respective category of data;
- a memory;
- and
- a data transfer logic coupled to said buffer and said memory, wherein said data transfer logic is further operable to transfer data from said buffer to said memory, wherein said data transfer logic is further operable to access said data from a first set of said plurality of sections responsive to a selection of a first format, and wherein said data transfer logic is further operable to access said data from a second set of said plurality of sections responsive to a selection of a second format.
4 more elements
A method of processing video data, said method comprising:
- accessing a selection of a format;
- in response to selection of a first format, accessing data from a first set of a plurality of sections of a buffer, wherein each section of said plurality of sections is associated with a respective category of data;
- in response to selection of a second format, accessing data from a second set of a plurality of sections of a buffer;
- and
- transferring said data to a memory.
