ABSTRACT:
A mechanism for programming a direct memory access engine operating as a single thread processor is provided. A program is received from a host processor in a local memory associated with the direct memory access engine. A request is received in the direct memory access engine from the host processor indicating that the program located in the local memory is to be executed. The direct memory access engine executes the program without intervention by a host processor. Responsive to the program completing execution, the direct memory access engine sends a completion notification to the host processor that indicates that the program has completed execution.
