英文摘要: We present a hybrid system spanning a fixed-function microarchitecture and a general-purpose microprocessor, designed to amplify the throughput and decrease the power dissipation of collision detection relative to what can be achieved using CPUs or GPUs alone. The primary component is one of the two novel microarchitectures designed to perform the principal elements of broad-phase collision detection. Both microarchitectures consist of pipelines comprising a plurality of memories, which rearrange the input into a format that maximises parallelism and bandwidth. The two microarchitectures are combined with the remainder of the system through an original method for sharing data between a ray tracer and the collision-detection microarchitectures to minimise data structure construction costs....
