Abstract: A system on a chip (SoC) includes a digital signal processor (DSP) and a graphics processing unit (GPU) coupled to the DSP. The DSP is configured to receive a stream of received depth measurements and generate a virtual bowl surface based on the stream of received depth measurements. The DSP is also configured to generate a bowl to physical camera mapping based on the virtual bowl surface. The GPU is configured to receive a first texture and receive a second texture. The GPU is also configured to perform physical camera to virtual camera transformation on the first texture and on the second texture, based on the bowl to physical camera mapping, to generate an output image.

Abstract: A method for displaying a surround view on a single display screen is disclosed. A plurality of image frames for a particular time may be received from a corresponding plurality of cameras. A viewpoint warp map corresponding to a predetermined first virtual viewpoint may be selected, wherein the viewpoint warp map defines a source pixel location in the plurality of image frames for each output pixel location in the display screen. The warp map was predetermined offline and stored for later use. An output image is synthesized for the display screen by selecting pixel data for each pixel of the output image from the plurality of image frames in accordance with the viewpoint warp map. The synthesized image is then displayed on a display screen.

Abstract: A method and system for dynamically transferring graphical image processing operations from a graphical processing unit (GPU) to a digital signal processor (DSP). The method includes estimating the number of operations needed for the processing a set of image data; determining the operational limits of a GPU and compare with estimated number of operations and if the operational limits are exceeded; transfer the processing operations to the DSP from the GPU. The transfer can include transferring a portion of executable code for performing the processing operations, and generating a replacement code for the GPU. The DSP can then process a portion of the image data before sending it to the GPU for further processing.

Abstract: Methods, apparatus, systems and articles of manufacture to perform graphics processing on combinations of graphic processing units and digital signal processors are disclosed. A disclosed example method includes processing first data representing input vertices to create second data, the first data using a first format organized by vertex, the second data using a second format organized by components of the vertices. A digital signal processor (DSP) is to perform vertex shading on the second data to create third data, the third data formatted using the second format, the vertex shading performed by executing a first instruction at the DSP, the first instruction generated based on a second instruction capable of being executed at a graphics processing unit (GPU). The third data is processed to create fourth data, the fourth data formatted using the first format.
