Abstract
A method for context switching on a video processor having a scalar execution unit and a vector execution unit. The method includes executing a first task and a second task on a vector execution unit. The first task in the second task can be from different respective contexts. The first task and the second task are each allocated to the vector execution unit from a scalar execution unit. The first task and the second task each comprise a plurality of work packages. In response to a switch notification, a work package boundary of the first task is designated. A context switch from the first task to the second task is then executed on the work package boundary.
