Abstract: Systems and methods are disclosed for error correction control (ECC) for a memory device comprising a data portion and an ECC portion, the memory device coupled to a system on a chip (SoC). The SoC includes an ECC cache. On receipt of a request to write a line of data to the memory, a determination is made if the data is compressible. If so, the data line is compressed. ECC bits are generated for the compressed or uncompressed data line. A determination is made if an ECC cache line is associated with the received data line. If the data line is compressible, the ECC bits are appended to the compressed data line and the appended data line is stored in the data portion of the memory. Otherwise, the ECC bits are stored in the ECC cache and the data line is stored in the data portion of the memory.

Abstract: A method performed by an electronic device is described. The method includes obtaining sensor data corresponding to multiple occupants from an interior of a vehicle. The method also includes obtaining, by a processor, at least one occupant status for at least one of the occupants based on a first portion of the sensor data. The method further includes identifying, by the processor, at least one vehicle operation in response to the at least one occupant status. The method additionally includes determining, by the processor, based at least on a second portion of the sensor data, whether to perform the at least one vehicle operation. The method also includes performing the at least one vehicle operation in a case that it is determined to perform the at least one vehicle operation.

Abstract: In an embodiment, a vehicle controller determines a predicted driving performance level of a vehicle driving control entity (VDCE) while the vehicle is controlled by a different VDCE. Driving control is transitioned to the VDCE, after which an actual driving performance level of the VDCE is monitored. The vehicle controller determines whether to transition driving control away from the VDCE based on the actual driving performance level. In another embodiment, after transition driving control to a VDCE, a period of heightened scrutiny used to evaluate the actual driving performance level of the VDCE specifically after the transition.
