DISPLAY SYSTEM

摘要

PURPOSE:To reduce the load of a CPU and to shorten the data transmission time by attaining a dynamic display on a screen just with the transfer of the program transfer data to a processor unit from the CPU. CONSTITUTION:The code of the data to be displayed is stored in a data memory 41, and a screen memory 42 is divided into a data region and an order region. The order region stores a display control program consisting of a prescribed order in order to perform a display in a prescribed format. While the data region stores the data which is referred to by an order setting up a flag at a prescribed bit position of the display control program in the form of the program transfer data. A firmware 62 sets a pointer in the memory 42 at 1 by a command of a CPU3 and then executes the display control program in turn from its head to develop the screen up to a refresh memory 2.
