  • Ensuring imaging subsystem integrity in camera based safety systems
    Patent number: 9628787
    Abstract: A method for testing an imaging subsystem of a system-on-a-chip (SOC) is provided that includes executing imaging subsystem test software instructions periodically on a processor of the SOC, receiving reference image data in the imaging subsystem responsive to the executing of the test software instructions, performing image signal processing on the reference image data by the imaging subsystem to generate processed reference image data, and using the processed reference image data by the test software instructions to verify whether or not the imaging subsystem is operating correctly.

  • System and method for managing cache
    Patent number: 9430393
    Abstract: A system includes first and second processing components, a qualified based splitter component, a first and second configurable cache element and an arbiter component. The first data processing component generates a first request for a first portion of data at a first location within a memory. The second data processing component generates a second request for a second portion of data at a second location within the memory. The qualifier based splitter component routes the first request and the second request based on a qualifier. The first configurable cache element enables or disables prefetching data within a first region of the memory. The second configurable cache element enables or disables prefetching data within a second region of the memory. The arbiter component routes the first request and the second request to the memory.
