Abstract :
The authors describe the architecture of the PixelStamp rendering processor and the implementation of that architecture for the DECstation 5000 Model 200. The PixelStamp architecture provides a range of 2-D and 3-D graphics subsystem implementations sensitive to both cost and performance. The first implementations of the PixelStamp architecture present a range of graphics subsystems for the DECstation 5000 Model 200. A PX module is an eight-plane double buffered system that increases the rendering performance over the basic color frame buffer, but has no special-purpose geometry processing hardware for 3-D applications. The PXG-8 module offers the same rendering hardware as the PX module, with the addition of special-purpose geometry processing hardware and an optional 24-b depth buffer. The PXG-24 module is an upgrade from the PXG-8 module to give 24 planes of color information, double buffered. The PXG Turbo module is a 24-plane system that increases the rendering performance with the addition of a Stamp chip.<>
