Abstract: This disclosure describes techniques that make use of a plurality of hardware elements that operate simultaneously to service synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises storing audio synthesis parameters generated for one or more audio files of an audio frame, processing a first audio synthesis parameter using a first audio processing element of a hardware unit to generate first audio information, processing a second audio synthesis parameter using a second audio processing element of the hardware unit to generate second audio information, and generating audio samples for the audio frame based at least in part on a combination of the first and second audio information.

Abstract: An embedded device is provided which comprises a device memory and hardware entities including a 3D graphics entity. The hardware entities are connected to the device memory, and at least some of the hardware entities perform actions involving access to and use of the device memory. A grid cell value buffer is provided, which is separate from the device memory. The buffer holds data, including buffered grid cell values. Portions of the 3D graphics entity access the buffered grid cell values in the buffer, in lieu of the portions directly accessing the grid cell values in the device memory, for per-grid processing by the portions.

Abstract: A graphics pipeline includes a plurality of sequentially arranged processing stages which render display pixel data from input primitive object data. The processing stages include at least a texturing stage and a depth test stage, and the depth test stage may be located earlier in the graphics pipeline than the texturing stage.
