CS 6958 PROJECT IDEAS 2

March 5, 2014

• 1. Visualizing memory access patterns

 How well do we use the full memory hierarchy?  Are we getting row buffer hits within DRAM

chips?

 Should we reorganize data, and how?

• 2. Advanced materials, shading, sampling

 Dielectrics, glossy, translucent

 How do we process/cast multiple seconds rays

when evaluating materials?

 Should we add a shading queue (to STRaTa)?  Additional materials cache?

5

• 3. Dedicated texture memory

 How do we access memory coherently?

Texture cache?

 Gather operations. Anisotropic filtering.  Interpolation and fetch units

6

• 4. Advanced rendering techniques

 How do these map well to TRaX?  What hardware changes would help make these

run quickly? Read/Write memory / framebuffer?
