A computing device and a method of performing crash analysis is provided. Each compute unit of an accelerated processor is configured to execute an application in a crash analysis operation mode, different from a normal operation mode, by executing a single instruction in isolation from any other instruction such that execution of the single instruction is completed prior to beginning execution of any of the other instructions. Examples of selectable crash analysis operation modes include a first mode in which execution of each memory instruction is completed prior to beginning execution of a next instruction, a second mode in which execution of each ALU instruction is completed prior to beginning execution of a next instruction, and a third mode in which execution of both memory and ALU instructions are completed prior to beginning execution of a next instruction.

Methods and systems for detecting vehicle crash events using real-time sensor data are disclosed. In some embodiments, an application executing on a computing device disposed in a vehicle receives a stream of time-series data from one or more motion sensors during a drive. For each contiguous interval of a first predefined length, the application generates a crash prediction indicative of whether a crash occurred during that interval. Generating the crash prediction includes executing a crash detection neural network on sensor data collected over a time period that comprises the interval and has a second, greater predefined length. For each crash prediction, the application determines whether the prediction meets one or more predefined threshold criteria. In response to meeting the criteria, the application generates a crash analysis using the corresponding sensor data.
