Abstract
Abstract In a display system, mode data representing a display mode written in a mode register (41) is also written into a buffer (44). An I/O decoder (42) checks whether or not the mode data is written into the mode register (41) and outputs an interruption command signal to an interrupt controller (5) when the mode data is written into the mode register (41). The interrupt controller (5) performs an interruption to a CPU (1) in accordance with the interruption command signal. By so doing, the CPU (1) starts a BIOS (2). The BIOS (2) reads the mode data from the buffer (44) and sets palette data in a palette register (43) in accordance with the mode data. In this way, the palette data can readily be set to the palette register (43) for each display mode.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A display system characterized by: a main processor (1); a plurality of display devices (6, 7) for displaying display data; mode data storing means (41) for storing mode data representing a display mode of the display device; buffer means (44) for storing the mode data; determining means (42) for determining whether or not the mode data is stored in the mode data storing means (41); interruption means (5) for generating an interruption for the main processor (1) in accordance with a determination result provided by the determining means (42); display control means (2) for generating palette data in accordance with the mode data stored in the buffer means (44) when the interruption is generated; and palette register means (43) for storing the generated palette data, wherein the display data is displayed in accordance with the palette data.
Claim 2
Dependent Claim
137 words
