A vector processor with a vector first and multi-lane configuration. A vector operation for a vector processor can include a single vector or multiple vectors as input. Multiple lanes for the input can be used to accelerate the operation in parallel.

A method and system for partial wavefront merger is described. Vector processing machines employ the partial wavefront merger to merge partial wavefronts into one or more wavefronts. The system includes a partial wavefront manager and unified registers. The partial wavefront manager detects wavefronts in different single-instruction-multiple-data (SIMD) units which contain inactive work items and active work items (hereinafter referred to as partial wavefronts), moves the partial wavefronts into one or more SIMD unit(s) and merges the partial wavefronts into one or more wavefront(s). The unified register allows each active work item in the one or more merged wavefront(s) to access the previously allocated registers in the originating SIMD units. Consequently, the contents of the unified registers do not have to be copied to the SIMD unit(s) executing the one or merged wavefront(s).

Systems for vehicles are disclosed using simplified state machines. For one example, a data processing system for a vehicle includes a plurality of subsystem nodes interconnected by a network topology. Each subsystem node includes a transceiver and micro-controller coupled to the transceiver. The micro-controller is configured to obtain an atomic machine state bit vector. Each bit of the atomic bit vector describes a state of the vehicle used by a state machine operating within the vehicle. The micro-controller multiplies a first bit vector mask with the atomic machine state bit vector to obtain a first result. The first result identifies first states of interest. The micro-controller determines a next state for the state machine based on the identified first states of interest. The micro-controller performs a function for the vehicle based on the determined next state. The atomic machine state bit vector can be updated based on the determined next state and distributed within the vehicle.
