A method and apparatus for storing sequential data words associated with a block of data in a non-linear manner within the data block is taught such that any row or column associated with the data block may be accessed using a burst access. A row, or column of data accessed by a burst frees up instruction bandwidth of a video controller. In particular, it is assured that each row and column of data associated with the data block has at least one sequential pair of data words associated with it. By assuring at least one sequential pair of data words, it is possible to issue a burst request for a minimum of two words of data with each row access, or column access of the video controller.
A method of accessing a block memory having X columns of words by Y rows of words, the method comprising the steps of:
A method of accessing data to a memory block, the method comprising:
A data processor for access a block of memory having X columns of words by Y
