Memory mapped interface between host computer and graphics system

摘要

An apparatus for graphics software development for execution in a graphics processor. The graphics processor resides in a host computer, which has a system bus and a video graphics array (VGA) for video enhanced display. The apparatus comprises a memory mapper coupled to the system bus for providing interface between the host computer and the apparatus, and a memory storage circuit coupled to the graphics processor for providing local memory space for storing data and access of the stored data. A video pass through multiplexer allows either the output of the memory storage circuit or the output of the VGA to be viewed on one monitor.
