Applications of the Global Frame Buffer to Volume Visualization

概要

論文の詳細を見る
In this work, the Global Frame Buffer(GFB)of the VC-1 and a new parallelized implementation of volume visualization is developed. VC-1 is a multiprocessor environment for computer graphics, and the GFB is used basically to isolate the image data that flows at the VC-1 from the data that is being displayed. VC-1 is a loosely-coupled multiprocessor with a frame buffer subsystem called Conflict-Free Multiport Frame Buffer(CFMFB). The CFMFB consists of Local frame buffers(LFBs), a pipelined image merger(PIM), and a global frame buffer(GFB). Every processor element(PE)has its own LFB to hold the sub-image(including Z-values)created by it. The PIM periodically superimposes the sub-images stored in the LFBs and transfers the merged picture to the GFB. To extend the functions of the GFB, an additional device called the merging unit for the accumulation buffer(MUACC)is introduced. This hardware device can enlarge the range of applications of the VC-1 and improves its general performance, transferring processing load from the processor elements to the GFB.
