Apparatus and method for graphics processing unit hybrid rendering

An apparatus for hybrid rendering of content, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• configure a graphics processing unit (GPU) of a display apparatus to perform a plurality of rendering passes for at least one frame of a scene to be displayed on a display device;
• control the GPU to perform a first rendering pass of the plurality of rendering passes using a first workload having a first complexity that exceeds a predetermined threshold to generate at least one first render target;
• select an on-chip graphics memory of the GPU based on the first complexity of the first workload exceeding the predetermined threshold to store the at least one first render target;
• control the GPU to perform a second rendering pass of the plurality of rendering passes using a second workload having a second complexity that does not exceed the predetermined threshold to generate at least one second render target;
• and
• select a system memory of the display apparatus based on the second complexity of the second workload not exceeding the predetermined threshold to store the at least one second render target.

A computer-readable medium storing computer executable code for hybrid rendering of content by a graphics processing unit (GPU), the code when executed by a processor causes the processor to:

• configure the GPU of a display apparatus to perform a plurality of rendering passes for at least one frame of a scene to be displayed on a display device;
• control the GPU to perform a first rendering pass of the plurality of rendering passes using a first workload having a first complexity that exceeds a predetermined threshold to generate at least one first render target;
• select an on-chip graphics memory of the GPU based on the first complexity of the first workload exceeding the predetermined threshold to store the at least one first render target;
• control the GPU to perform a second rendering pass of the plurality of rendering passes using a second workload having a second complexity that does not exceed the predetermined threshold to generate at least one second render target;
• and
• select a system memory of the display apparatus based on the second complexity of the second workload not exceeding the predetermined threshold to store the at least one second render target.
