摘要： An image data frame is received from an external source. An error concealment operation is performed on the received image data frame in response to determining that a first frame size of the received image data frame is erroneous. The first frame size of the image data frame is determined to be erroneous based on at least one frame synchronization signal associated with the image data frame. An image processing operation is performed on the received image data frame on which the error concealment operation has been performed, thereby enabling an image processing module to perform the image processing operation without entering into a deadlock state and thereby prevent a host processor from having to execute hardware resets of deadlocked modules.

摘要： A method and system for dynamically transferring graphical image processing operations from a graphical processing unit (GPU) to a digital signal processor (DSP). The method includes estimating the number of operations needed for the processing a set of image data; determining the operational limits of a GPU and compare with estimated number of operations and if the operational limits are exceeded; transfer the processing operations to the DSP from the GPU. The transfer can include transferring a portion of executable code for performing the processing operations, and generating a replacement code for the GPU. The DSP can then process a portion of the image data before sending it to the GPU for further processing.

摘要： Systems and methods for performing Census Transforms that includes an input from an image, with a support window created within the image, and a kernel within the support window. The Census Transform calculations and comparisons are performed within the kernel windows. One disclosed method allows for previously performed comparison to be calculated and compared as an if not equal invert or if equal use pervious comparison hardware design. Alternatively, a new Census Transform is disclosed which always inverts a previously made comparison. This new approach can be demonstrated to be equivalent to, applying the original Census Transform, on a pre-processed input kernel, where the pre-processing step adds a fractional position index to each pixel within the N×N kernel. The fractional positional index ensures that no two pixels are equal to one another, and thereby makes the Original Census algorithm on pre-processed kernel same as the new Census algorithm on original kernel. The hardware design for this new Census Transform kernel allows for an always invert of previous comparison system resulting in reduced hardware and power consumption.

摘要： 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.

摘要： Devices, systems, and methods detect an image frame freeze condition. An example device includes a core logic circuit configured to generate statistics for received image data associated with an image frame, perform a census transform on pixel values of the image data to generate census transformed data, arrange the census transformed data into a binary string having a binary value, and generate transformed image data by replacing a select pixel value of the pixel values of the image data with a decimal value corresponding to the binary value; a load/store engine (LSE) coupled to the core logic circuit, the LSE configured to determine a cyclic redundancy check (CRC) value based on at least one of the image data, the transformed image data, and at least one statistic of the statistics; and an interface configured to transmit the CRC value to a host device.
