Abstract: A rendering method executed by a graphics processing unit includes: loading a vertex shading command from a first command queue to a shader module; executing the vertex shading command for computing the varying of the vertices to perform a vertex shading operation by taking the vertices as first input data; storing first tessellation stage commands into a second command queue; loading the first tessellation stage commands to the shader module; and executing the first tessellation commands for computing first tessellation stage outputs to perform a first tessellation stage of the one or more tessellation stages by taking the varying of the vertices as second input data. The vertex shading command is stored into the first command queue by a first processing unit. The varying of the vertices and the first tessellation stage outputs are stored in a cache of the graphics processing unit.

Abstract: A heterogeneous computing system described herein has an energy-efficient architecture that exploits producer-consumer locality, task parallelism and data parallelism. The heterogeneous computing system includes a task frontend that dispatches tasks and updated tasks from queues for execution based on properties associated with the queues, and execution units that include a first subset acting as producers to execute the tasks and generate the updated tasks, and a second subset acting as consumers to execute the updated tasks. The execution units includes one or more control processors to perform control operations, vector processors to perform vector operations, and accelerators to perform multimedia signal processing operations. The heterogeneous computing system also includes a memory backend containing the queues to store the tasks and the updated tasks for execution by the execution units.
