Methods and apparatus for mapping source location for input data to a graphics processing unit

An apparatus for mapping a source location of input data for processing by a graphics processing unit, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• configure a processing element of the graphics processing unit with at least one predefined rule for decoding a data source parameter for a task to be executed by the graphics processing unit;
• store the data source parameter in local storage of the processing element;
• configure the processing element to decode the data source parameter according to the at least one predefined rule to determine a source location of the input data and at least one relationship between invocations of the task;
• load, to the local storage of the processing element, the input data from a plurality of memory addresses of the source location that are determined by the decoded data source parameter;
• and
• configure at least one logic unit of the processing element to execute the task on the loaded input data to generate output data.

A computer-readable medium storing computer executable code for mapping a source location of input data for processing by a graphics processing unit, the code when executed by a processor causes the processor to:

• configure a processing element of the graphics processing unit with at least one predefined rule for decoding a data source parameter for a task to be executed by the graphics processing unit;
• store the data source parameter in local storage of the processing element;
• configure the processing element to decode the data source parameter according to the at least one predefined rule to determine a source location of the input data and at least one relationship between invocations of the task;
• loading, to the local storage of the processing element, the input data from a plurality of memory addresses of the source location that are determined by the decoded data source parameter;
• and
• control at least one logic unit of the processing element to execute the task on the loaded input data to generate output data.
