    摘要： In various embodiments, a dynamic range converter includes a plurality of circuits, including at least one configurable circuit that operates based on configuration data. The plurality of circuits include a first color space converter to convert a source color space of a source video having a source dynamic range to nonlinear color space signals. A linearizer configured converts the nonlinear color space signals to linearized color space signals having a mastering dynamic range via a piecewise linear interpolation of a transfer function. A color volume transformer applies dynamic color transform metadata associated with the source video to generate master adjusted color space signals from the linearized color space signals. A delinearizer converts the master adjusted color space signals to nonlinearized color space signals via a piecewise linear interpolation of an inverse transfer function in accordance with a display dynamic range. A second color space converter converts the nonlinearized color space signals to display domain signals. Other embodiments are disclosed.

    摘要： An apparatus includes a first data processor configured to communicate first data and handshake information to a non-coherent memory system. The apparatus includes a second data processor coupled in a pipeline with the first data processor and configured to execute in parallel with the first data processor. The second data processor is configured to read the first data from the non-coherent memory system in response to receiving an indicator from the non-coherent memory system based on the handshake information. The apparatus may include the non-coherent memory system. The non-coherent memory system may include a memory controller configured to receive the first data and the handshake information, the memory controller being configured to provide the indicator in response to the first data being available for a read.

A linearizer configured converts the nonlinear color space signals to linearized color space signals having a mastering dynamic range via a piecewise linear interpolation of a transfer function.

A delinearizer converts the master adjusted color space signals to nonlinearized color space signals via a piecewise linear interpolation of an inverse transfer function in accordance with a display dynamic range. A second color space converter converts the nonlinearized color space signals to display domain signals. Other embodiments are disclosed.
