In a computing device having a pipeline of image processing components, DCVS bandwidth voting may be based on a feedforward compression ratio determined by the first image processing component in the pipeline. The DCVS bandwidth voting may be based on the result of a comparison of change in the feedforward compression ratio with a threshold. Transaction initiator components in the pipeline may select their votes for bandwidth from among a feedforward compression ratio-based value and one or more other values, based on the result of the comparison with the threshold. DCVS parameters may be selected based on bandwidth votes received from transaction initiator components.

Information communication circuitry, including a first integrated circuit for coupling to a second integrated circuit in a package on package configuration. The first integrated circuit comprises processing circuitry for communicating information bits, and the information bits comprise data bits and error correction bits, where the error correction bits are for indicating whether data bits are received correctly. The second integrated circuit comprises a memory for receiving and storing at least some of the information bits. The information communication circuitry also includes interfacing circuitry for selectively communicating, along a number of conductors, between the package on package configuration. In a first instance, the interfacing circuitry selectively communicates only data bits along the number of conductors. In a second instance, the interfacing circuitry selectively communicates data bits along a first set of the number of conductors and error correction bits along a second set of the number of conductors.

Embodiments include methods for image compression and decompression. A sending computing device may determine a type of packing used for a chunk of image data, generate metadata describing the type of packing used for the chunk of image data, pack the chunk of image data according to the determined type of packing, and send the packed chunk of image data and the metadata to a second computing device. A receiving computing device may decode the metadata describing the type of packing used for the chunk of image data, determine the type of packing used for the chunk of image data based on the decoded metadata, and unpack the chunk of image data according to the determined type of packing used for the chunk of image data.

Image compression and decompression

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.

Ensuring imaging subsystem integrity in camera based safety systems

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.
