Abstract: An integrated circuit includes a display sub-system that has a plurality of image processing resources and control logic. The image processing resources include a plurality of image processing pipelines configured to operate in parallel, overlay logic coupled to receive image data from the plurality of image processing pipelines, and an image output port coupled to an output of the overlay logic with image data outputs configured to couple to one or more display devices. The control logic is dynamically configurable to assign each of the image processing resources to a selected one of a first control port and a second control port. The first control port is configured to be controlled exclusively by a first processor and the second control port is configured to be controlled exclusively by a second processor.

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.

Abstract: An Ethernet switch and a switch microcontroller or CPU are integrated onto a system-on-a-chip (SoC). The Ethernet switch remains independently operating at full speed even though the remainder of the SoC is being reset or is otherwise nonoperational. The Ethernet switch is on a separated power and clock domain from the remainder of the integrated SoC. A warm reset signal is trapped by control microcontroller (MCU) to allow the switch CPU to isolate the Ethernet switch and save state. When the Ethernet switch is isolated and operating independently, the warm reset request is provided to the other entities on the integrated SoC. When warm reset is completed, the state is restored and the various DMA and flow settings redeveloped in the integrated SoC to allow return to normal operating condition.

Abstract: This disclosure relates to various implementations an embedded computing system. The embedded computing system comprises a hardware accelerator (HWA) thread user and a second HWA thread user that creates and sends out message requests. The HWA thread user and the second HWA thread user is communication with a microcontroller (MCU) subsystem. The embedded computing system also comprises a first inter-processor communication (IPC) interface between the HWA thread user and the MCU subsystem and a second IPC interface between the second HWA thread user and the MCU subsystem, where the first IPC interface is isolated from the second IPC interface. The MCU subsystem is also in communication with a first domain specific HWA and a second domain specific HWA.

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: An electronic device may be configured to detect a fault in imaging and vision hardware accelerators. The electronic device may include a controller configured to select a first golden input frame of multiple golden input frames to perform a first self-test, and retrieve a first reference image signature corresponding to the first golden input frame. The electronic device may include a hardware accelerator module configured to obtain the first golden input frame, and generate a first output frame based on the first golden input frame. The electronic device may include a signature generator configured to generate a first generated image signature based on the first output frame. The electronic device may include a signature comparison module configured to compare the first generated image signature to the first reference image signature in order to determine whether the hardware accelerator module includes a fault at a first time.
