ABSTRACT:
A display management system for one or more large plasma gas panel displays (11) is organized to split the display management operations between a host processor (20), a system microprocessor (21) and a picoprocessor (27). The picoprocessor (27) is the heart of a common internal bus (31) plasma display adapter (22). The program for the display is downloaded from the host processor (20) to the system microprocessor (21). The microprocessor generates op codes and initializes display parameters. The plasma display adapter provides control for the plasma panel interface, serialization of character generator data, translates display position addresses for absolute cartesian coordinates to panel address, and computes the boundaries of display panel write and erase operations. Interaction between the system microprocessor and the plasma display adapter is minimized by a code list contained in the microprocessor memory and fetched by direct memory access. This code list contains high level commands which the picoprocessor in the adapter decodes and translates into simple commands for the surrounding interface logic.
