Abstract: A fault reaction handling time interval (FRTI) for a reaction to the fault is determined based on a domain identifier (DID) indicative of an application associated with a fault. A first reaction to recover from the fault is signaled and then a determination is made whether a safe state is reached after the FRTI. Based on the safe state not being reached, a second FRTI is determined for a second escalated reaction, the second FRTI also being based on the DID. Typically, the second reaction results in less system availability so by defining the FRTI based on the DID sufficient time is allowed for reaching a safe state before the reaction is escalated.

Abstract: A multiple core processing system as described herein for optimizing broadcast operations includes multiple first-level (L1) caches, a distributed second-level (L2) cache system including multiple L2 cache partitions each having a unique identifier, and a routing network that enable communications between the L1 and L2 caches. Each L1 cache sends a request message with a memory address to a targeted L2 cache partition.

Each L2 cache partition sends a reject message to a requesting Li cache when busy and later broadcasts a retry message that incorporates its identifier when not busy. The L1 cache predetermines the identifier of the target L2 cache partition when sending the request, or each L2 cache partition incorporates its identifier in the reject message.

Abstract: Techniques for using machine learning to produce vehicle location sensor data from vision sensor data are disclosed. By using a limited amount of vehicle location sensor data together with vision sensor data, a deep learning network can be trained to produce estimated vehicle location sensor point cloud distributions from, e.g., vision sensor data alone.

These estimated vehicle location sensor point cloud distributions can then be compared with general sensor point cloud distributions to improve detection of vehicles, environmental objects, and ghost objects, and subsequently used to improve vehicle safety through vehicle controls or driver notifications and/or to produce enhanced sensor data.
