Ray tracing efficiently models complex illumination effects to improve visual realism in computer graphics. Typical modern GPUs use wide SIMD processing, and have achieved impressive performance for a ...

In today’s automobiles, manufacturers competitively blend performance and custom features with cutting-edge safety technology. In today’s automobiles, manufacturers competitively blend ...

This paper describes the design and LSI implementation of a dynamic SIMD/MIMD mode switching processor core (the XC core) for embedded real-time image recognition systems. The XC core supports both a ...

However, SIMD efficiency can be reduced due to the divergent branching and memory access patterns that are common in ray tracing codes. This paper explores an alternative approach using MIMD ...
