Rastergraf RG-750

Overview

The RG-750 is a high performance 6U graphics board, powered by the TMS34010 graphics processor, and designed for VMEbus applications. Major features of the RG- 750 are its on-board AFGIS firmware with over 250 highly optimized graphics primitives for easy graphics programing, its ability to support real-time multi-tasking operating systems with its unique pointer based graphics environment, its advanced hardware architecture with mouse and keyboard interfaces, and extensive C programing support.

The RG-750 is ideal for simple embedded system applications, because it is easy to program and because it does its own local graphics processing, freeing the VMEbus host to do other things while the RG-750 is creating graphics in parallel.

The real power and versatility of the RG-750 is evident when it is used with real-time multi-tasking operating systems that require several tasks to independently generate graphics on the video screen. Each task can have its own colors, font, screen position, etc., and can independently create graphics on the video screen without affecting the colors, font, screen position, etc. of any other task.

The combination of advanced hardware architecture, optimized on-board graphics primitives, and extensive C programing support, make the RG-750 an ideal low cost, high performance solution for many of today's challenging graphics opportunities.
