چکیده
The optimal architecture of personal digital assistants (PDA) system for real-time 3D graphics was analyzed by simulating the 3D applications on the various Advanced RISC Machines (ARM) processor platforms. Simulation results show that for 256x256 screen resolution, even the performance of 200MHz StrongARM with 160MHz floating point unit (FPU) shows only 1.78 % of the requirement of full 3D pipeline. To realize the real-time 3D graphics on PDA, the optimal architecture must contain hardware acceleration engine with embedded DRAM as the rendering stage. In this architecture, MACenhanced ARM9 without FPU that is used as a host processor can provide the necessary geometry operations and we verified this architecture by the implementation of a PDA chip.

We outline our seamless tiled display system for interactive 3D graphics applications that is low-cost, easy to calibrate, scalable, and portable. Our system achieves geometric alignment in software by pre-warping the 3D space in contrast with the current systems that usually achieve this by 2D image pre-warping. Our system accomplishes this through real-time image capture from a digital camcor...
