Abstract: A method of analyzing a digital camera includes generating first image data using an image sensor in the camera. A first analysis is performed on at least one portion of the first image data. Second image data is generated using the image sensor and a second analysis is performed on the at least one portion of the second image data. The results of the first analysis are compared to the results of the second analysis. A signal indicating a fault with the digital camera is generated in response to the first analysis differing from the second analysis by a predetermined amount.

Abstract: Methods, apparatus, systems and articles of manufacture for an example event processor are disclosed to retrieve an input event and an input event timestamp corresponding to the input event, generate an output event based on the input event and the input event timestamp, in response to determination that an input event threshold is exceeded within a threshold of time, and an anomaly detector to retrieve the output event, determine whether the output event indicates threat to functional safety of a system on a chip, and in response to determining the output event indicates threat to functional safety of the system on a chip, adapt a process for the system on a chip to preserve functional safety.

Abstract: A reconfigurable image processing pipeline includes an image signal processor (ISP), a control processor, and a local memory. ISP processes raw pixel data for a frame based on an image processing parameter and provides lines of processed pixel data to control processor via a first interface. For each region of interest (ROI) in the frame, ISP generates auto-exposure and auto-white balance (2A) statistics based on the lines for the ROI and writes them to the local memory via a second interface. Control processor reads 2A statistics from the local memory, determines the image processing parameter based on them, and provides the image processing parameter to ISP. ISP also generates an integer N bin histogram for control processor, which sums a portion of the N total bins and compares the summed bin count to a lighting transition threshold. The image processing parameter is further based on the comparison.

Abstract: Methods and apparatus to extend local buffer of a hardware accelerator are disclosed herein. In some examples, an apparatus, including a local memory, a first hardware accelerator (HWA), a second HWA, the second HWA and the first HWA connected in a flexible data pipeline, and a spare scheduler to manage, in response to the spare scheduler inserted in the flexible data pipeline, data movement between the first HWA and the second HWA through the local memory and a memory. Local buffer extension may be performed by software to control data movement between local memory and other system memory. The other system memory may be on-chip memory and/or external memory. The HWA sub-system includes a set of spare schedulers to manage the data movement. Data aggregation may be performed in the other system memory. Additionally, the other system memory may be utilized for conversion between data line and data block.

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: An optical flow system includes a binary mask generation circuit and an optical flow circuit. The binary mask generation circuit is configured to receive a plurality of points of interest from a captured image that contains an array of pixels arranged as rows and columns and includes width lines that correspond to the rows and height lines that correspond to the columns. The binary mask generation circuit is also configured to generate a binary mask based on the plurality of points of interest. The binary mask includes a representation of a subset of the plurality of points of interest. The optical flow circuit is configured to receive the binary mask and generate an optical flow map of the subset of the plurality of points of interest.
