The real time 3D graphics becomes one of the attractive applications for 3G wireless terminals although their battery lifetime and memory bandwidth limit the system resources for graphics processing. Instead of using the dedicated hardware engine with complex functions, we propose an efficient hardware architecture of low power vertex shader with(More)
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(More)
As mobile applications are moving to realtime multimedia, more functions are integrated into handheld devices [1-4]. Unlike the realtime decoding of MPEG-4 video [1,4], the performances of hardware-accelerated 3D solutions designed for mobile platforms are still below the market demands showing only limited shading operations [2,3]. Since the realization of(More)
