Abstract
A data processing system can comprise a first module having a workspace and configured to execute a task that can request access to a frame in a system memory, a queue manager configured to store a frame descriptor which identifies the frame in the system memory, and a memory access engine coupled to the first module and the queue manager. The memory access engine copies requested segments of the frame to the workspace and has a working frame unit to store a segment handle identifying a location and size of each requested segment copied to the workspace of the first module. The memory access engine tracks history of a requested segment by updating the working frame unit when the requested segment in the workspace is modified by the executing task.
