RT Engine: An Efficient Hardware Architecture for Ray Tracing

An efficient parallel architecture for ray-tracing

Real time rendering of three-dimensional scenes in high photorealistic details is a hard task, such as in the ray tracing rendering algorithm. In general, the performance achieved by a sequential software-based implementation of ray tracing is far from satisfactory. However, parallel implementations of ray tracing have been enabling reasonable real time performance, as the algorithm is embarras...

TigerSHARK A Hardware Accelerated Ray-tracing Engine

The current state of the art in graphics rendering algorithms and hardware is surveyed, and it is shown that ray-tracing, despite larger computational requirements than conventional algorithms, is more amenable to massive parallelism. The TigerSHARK ray-tracing architecture is then presented as an extremely cost-effective means to exploit this fundamental parallelism. A competing approach is an...

A Virtual Memory Architecture for Ray Tracing Hardware

A virtual memory architecture for real-time ray tracing hardware

Real-time ray tracing offers a number of interesting benefits over current rasterization techniques. However, a major drawback has been that ray tracing requires access to the entire scene data base. This is particularly problematic for hardware implementations that only have a limited amount of dedicated on-board memory. In this paper we propose a virtual memory architecture for ray tracing th...

Hardware Prototyping of an Efficient Encryption Engine

An approach to develop the FPGA of a flexible key RSA encryption engine that can be used as a standard device in the secured communication system is presented. The VHDL modeling of this RSA encryption engine has the unique characteristics of supporting multiple key sizes, thus can easily be fit into the systems that require different levels of security. A simple nested loop addition and subtrac...
