Document Type and Number:
Japanese Patent JPS5854440
Kind Code:
A
Abstract:
PURPOSE: To freely change a display picture partially in the order of the generation of change without increasing the contents of a program, by storing information of displayed data to be changed in a FIFO buffer.
CONSTITUTION: A data controlling device 1 and a display device 2 are controlled by CPUs 10, 20, respectively. Data and interruption signals indicating the change of data are inputted from an external sensor to the CPU10. The CPU20 is provided with a program storing ROM21 for display control and a display data storing RAM22. Between both CPUs 1, 2, data are transmitted by using standarized frame format telegrams. In addition, transmission controlling interfaces 13, 23 are connected in order to control the transmission.
