Abstract: Aspects presented herein may enable a device to detect memory faults during idle cycles of the memories or memory blocks using a clock gating logic to trigger memory self-tests, thereby improving safety coverage and early fault detection without affecting the functional logic of the system. In one aspect, a device identifies at least one block of at least one processor is in an idle mode, where the at least one block corresponds to a set of memories in the at least one processor. The device triggers, based on identification of the at least one block is in the idle mode, the at least one block to perform a self-test for checking whether one or more memories in the at least one block includes a fault. The device outputs an indication of the fault if the fault is detected in the one or more memories of the at least one block.

Abstract: A method for hardware-based periodic self-testing of safety mechanisms includes generating a test pattern after data processing has initiated in at least one block of a processor. The test pattern is provided to a safety mechanism. The safety mechanism generates a syndrome based on the test pattern. A fault in the safety mechanism is determined based on the syndrome.

Abstract: This disclosure provides systems, methods, and devices for memory systems that support detecting and tracking a quantity of errors in memory using a counter and indicating the detection and quantity of errors using an interrupt flag. In a first aspect, a method includes, at a hardware of a memory system detecting one or more errors at a memory. The method includes counting a quantity of the one or more errors until the quantity is equal to or greater than a threshold quantity of errors. The method includes recording the quantity of errors and an error type in an error log. The method includes transmitting an indication that the quantity of errors of the memory is equal to or greater than the threshold. Other aspects and features are also claimed and described.

Abstract: A method includes detecting a functional safety fault and determining whether the functional safety fault is a transient fault or a permanent fault. The method further includes identifying a scalable block of a processing unit from which the functional safety fault occurred in response to the functional safety fault being determined to be a permanent fault. The method optionally includes power collapsing the scalable block. The method also includes notifying a scheduler to prevent the scheduler from scheduling future workloads to the scalable block.

Abstract: Methods and apparatuses directed to memory fault detection mechanisms within die architectures. In some examples, a die package includes decoder logic that receives multiple data words, and a first error correcting code for each of the data words. The decoder logic generates, for each of the data words, a second error correcting code based on a corresponding one of the data words. Further, the decoder logic generates, for each of the data words, an error status based on the first error correcting code and the second error correcting code that corresponds to each of the data words. The die package also includes error generation logic that receives the error status for the data words from the decoder logic, and generates error data based on a combination of the error statuses for the data words. The error generation logic can store the error data in a memory device.

Abstract: A method for managing a plurality of imaging devices in a vehicle includes determining that a change of data security mode is indicated for frames of image data transmitted over a first data communication link, determining whether a sensor management system has sufficient processing capacity to support the change of data security mode, increasing the processing capacity of the sensor management system by modifying data security settings for at least one other data communication link when the processing capacity of the sensor management system is insufficient to support the change of data security mode, and initiating the change of data security mode when the sensor management system has sufficient processing capacity to support the change of data security mode. The change of data security mode may include a change from an application-based to a link-based data security mode or a change from the link-based to the application-based data security mode.
