Abstract :
The gap between processor speed and memory access time limits the performance of memory-intensive applications such as volume rendering. In this paper we compare the performance of stages of the splatting volume rendering algorithm on a workstation and on the Computational RAM (C·RAM) simulator. C·RAM is a Processor-in-Memory architecture, which integrates SIMD processing elements into the memory array. These processing elements exploit the highest bandwidth available in the memory chip-at the sense amplifiers. Each stage executes faster on C·RAM
