Apparatus and methods for the handling of banded frame buffer overflows

摘要

A method is provided for handling overflows of data blocks in a system using a banded buffer. A block of data is transferred from a memory to a first band in the banded buffer. A determination is made that a portion of the block of data being transferred exceeds a boundary of the first band, and in response a description block for the portion of the block of data which exceeds the boundary of the first band is created. The description block is written into a memory queue and when a second band in the banded buffer becomes available, that portion of the data block which exceed the boundary of the first buffer band is transferred into the second buffer band in accordance with the description block.
