Abstract: A method in a multiprocessor system for processing multiple perception streams is disclosed. The method comprises: reading data from a plurality of perception streams according to a reading schedule determined by a predetermined policy, each perception stream comprising perception data from a different perception sensor; assigning a unique identification tag to each perception stream; writing each perception stream with its unique identification tag to a server input queue based on the predetermined policy; and processing the tagged perception streams using a server. The processing includes: retrieving tagged perception streams from the server input queue; applying a processing algorithm to process the retrieved tagged perception streams; and outputting the processed perception streams to a server output queue. The method further includes retrieving the processed perception streams from the server output queue and dispatching each retrieved processed perception stream to an appropriate post-processing destination based on the tag associated with the retrieved processed perception stream.

Abstract: Presented herein are intrusion detection systems and algorithms for networked vehicle controllers and devices, methods for making/using such systems and algorithms, and motor vehicles with a network of ECUs and network-profiling intrusion detection capabilities. A method for detecting intrusions into an onboard network of vehicle controllers includes determining the current state of operation of a vehicle, and identifying a network traffic pattern table corresponding to the vehicle's current state of operation. Network traffic flow for one of the in-vehicle controllers is monitored when exchanging data over the Ethernet communication interface while the motor vehicle is operating in the current state of operation. The method then determines if a traffic characteristic of the monitored network traffic flow is outside a calibrated boundary that is determined from the network traffic pattern table. Responsive to the monitored network traffic flow characteristic being outside the calibrated boundary, the method executes a remedial action response.

Abstract: Examples of techniques for dynamically selecting a batch size used in vehicle camera image processing are disclosed. In one example implementation, a method includes generating, by a processing device, a batch table and a mode table. The method further includes determining, by the processing device, image processing performance requirements for a current mode of a vehicle using the mode table, the vehicle comprising a plurality of cameras configured to capture a plurality of images. The method further includes selecting, by the processing device, a batch size and a processing frequency based at least in part on the image processing performance requirements for the current mode of the vehicle. The method further includes processing, by an accelerator, at least a subset of the plurality of images based at least in part on the batch size and processing frequency.

Abstract: Methods and systems are provided for controlling a temperature of a processor of a controller. In one embodiment, a method includes: identifying a status of at least one task of a plurality of software tasks performed on a first processor to be a hot task based on the software task's contribution to a temperature of the first processor; and selectively controlling the temperature of the first processor based on the identified status.
