    Abstract: An integrated circuit includes: a local memory; and a first processing circuit coupled to the local memory. The first processing component is configured to: receive a first set of image data; perform a first image processing operation on the first set of image data to produce a second set of image data; and store at least some of the second set of image data into the local memory. The integrated circuit also includes a second processing circuit coupled to the local memory and configured to: receive at least some of the second set of image data from the local memory; and perform a second image processing operation on the second set of image data to produce a third set of image data.

    Abstract: A hub that receives sensor data streams and then distributes the data streams to the various systems that use the sensor data. A demultiplexer (demux) receives the streams, filters out undesired streams and provides desired streams to the proper multiplexer (mux) or muxes of a series of muxes. Each mux combines received streams and provides an output stream to a respective formatter or output block. The formatter or output block is configured based on the destination of the mux output stream, such as an image signal processor, a processor, memory or external transmission. The output block reformats the received stream to a format appropriate for the recipient and then provides the reformatted stream to that recipient.

    Abstract: Several systems and methods for processing of video frames based on one or more video formats are disclosed. In an embodiment, a video processing system comprises a memory and a video engine. The memory stores a plurality of video frames, a primary set of instructions and a plurality of secondary sets of processing instructions. Each secondary set of processing instructions is associated with a video format. The video engine is loaded with the primary set of instructions and is configured to fetch one or more video frames and a secondary set of processing instructions from the memory based on the loaded primary set of instructions. The fetched secondary set of processing instructions corresponds to a video format determined for processing of the one or more video frames. The video engine performs processing of the one or more video frames based on the secondary set of processing instructions.

    Abstract: A configurable multi-function Peripheral Component Interchange Express (PCIe) endpoint controller, integrated in a system-on-chip (SoC), that exposes multiple functions of multiple processing subsystems (e.g., peripherals) to a host. The SoC may include a centralized transaction tunneling unit and a multi-function interrupt manager. The processing subsystems output data to the host via the centralized transaction tunneling unit, which translates addresses provided by the host to a local address of the SoC. Therefore, the centralized transaction tunneling unit enables those processing subsystems to consume addresses provided by the host without the need for software intervention and software-based translation. The SoC may also provide isolation between each function provided by the processing systems. The multi-function interrupt manager enables the endpoint controller to propagate interrupt messages received from the processing subsystems to the host.
