Abstract: A perception processing system includes a memory and a main controller. The main controller includes modules and implements a data processing pipeline including algorithm stages, which are executed in parallel relative to sets of data and are executed sequentially relative to each of the sets of data. The algorithm stages share resources of the modules and the memory to process the sets of data and generate perception information. One of the modules executes global and local controllers. The global controller sets a processing rate for the local controllers. The local controllers monitor current processing rates of the algorithm stages. When one of the current processing rates is less than the set processing rate, the corresponding one of the local controllers sends a first signal to the global controller and in response the global controller sends a broadcast signal to the local controllers to adjust the current processing rates.

Abstract: A system includes a queue, a memory and a controller. The queue is configured to transfer a message between a first thread and a second thread, where the first thread and the second thread are implemented as part of a single process, and where an amount of data corresponding to the message is less than a set amount of data. The memory is configured for sharing data between the first thread and the second thread, wherein an amount of the data shared between the first thread and the second thread is greater than the set amount of data. The controller is configured to execute the single process including concurrently executing (i) a first middleware node process as the first thread, and (ii) a second middleware node process as the second thread.

Abstract: Methods and systems are provided for controlling a temperature of a processor of a controller. In one embodiment, a method includes: collecting a first set of measurement data based on measurement parameters; processing the first set of measurement data associated with the processor using a predictor model to determine a temperature of the processor; and selectively controlling the temperature of the processor based on the determined temperature.
