Abstract: Devices, systems and techniques for implementing freedom from interference (FFI) access rules. In an example, a device includes a set of primary components, a set of secondary components, and an interconnected coupled between the two sets of components. Each primary component of the set of primary components has an access identifier, among multiple access attributes, and an access attribute, among multiple access modes. Each secondary component of the set of secondary components is protected by a firewall. Each firewall is configured to specify, for each specific combination of an access identifier and access attribute, whether access to the associated secondary component is permitted and what type of access is permitted.

The method includes storing shared code for the first CPU and the second CPU in a third region of the memory. The method includes storing read-write data for the first CPU in a fourth region of the memory and storing read-write data for the second CPU in a fifth region of the memory. The method includes translating a first address from a first unique address space for the first CPU to a shared address space in the third region, and translating a second address from a second unique address space for the second CPU to the shared address space in the third region.

Abstract: In an example, a method includes receiving image data of an input image having lines therein. The method also includes storing a first portion of the image data in a circular buffer in a first memory, wherein the first portion begins at a circular buffer start line in the input image and ends at a circular buffer end line in the input image. The method includes storing a second portion of the image data in a linear buffer in a second memory, where the second portion is non-overlapping with the first portion. The method includes processing the second portion of the image data to produce a first block of an output image. The method includes processing the first portion of the image data to produce a second block of the output image.

Abstract: In an advanced driver-assistance system (ADAS), RAW sensor image processing for a machine vision (MV) application is important. Due to different color, e.g., red/green/blue (RGB), color components, being focused by the lens at different locations in image plane, the lateral chromatic aberration phenomenon may sometimes be observed, which causes false color around edges in the final image output, especially for high contrast edges, which can impede MV applications. Disclosed herein are low-latency, efficient, optimized designs for chromatic aberration correction (CAC) components. An in-pipeline CAC design may be used to perform on-the-fly CAC without any out-of-pipeline memory traffic; enable use of wide dynamic range (WDR) sensors; uses bicubic interpolation; support vertical and horizontal chromatic aberration color channel offsets, reduce CAC line memory requirements, and support flexible look-up table (LUT) down-sampling factors to improve the spatial precision of correction and accommodate popular image sensor resolutions.

Abstract: Techniques including a memory controller with a set of memory channel queues, wherein memory channel queues of the set of memory channel queues correspond to memory channels to access a set of memory modules, a first arbitration module, and a second arbitration module. The memory controller is configured to receive a first memory request from the peripheral and place one or more portions of the first memory request in the memory channel queues of the set of memory channel queues. The first arbitration module is configured to determine an arbitration algorithm, select a first memory channel queue based on the arbitration algorithm, present the one or more portions of the first memory request in the selected first memory channel queue to the second arbitration module, and output the presented one or more portions of the first memory request based on a selection by the second arbitration module.

Abstract: A method of enabling memory access freedom from interference (FFI) rules, comprising: determining a first safety privilege access ID (PrivID) for a first component of a system (e.g., based on Automotive Safety Integrity Level (ASIL) attributes of tasks executed by the first component); determining a first access attribute for a first software task executing on the first component; receiving, at a first firewall component of the system, a request from the first software task to access a first memory region of a second component of the system, wherein the request specifies the first PrivID and the first access attribute; and determining, by the first firewall component, whether to permit the first software task to access the first memory region based on the first PrivID, the first access attribute, and the first memory region.

Abstract: A method of de-mosaicing pixel data from an image processor includes generating a pixel block that includes a plurality of image pixels. The method also includes determining a first image gradient between a first set of pixels of the pixel block and a second image gradient between a second set of pixels of the pixel block. The method also includes determining a first adaptive threshold value based on intensity of a third set of pixels of the pixel block. The pixels of the third set of pixels are adjacent to one another. The method also includes filtering the pixel block in a vertical, horizontal, or neutral direction based on the first and second image gradients and the first adaptive threshold value utilizing a plurality of FIR filters to generate a plurality of component images.
