Title:
TRANSFERRING METHOD OF DATA DISPLAYED BY BCD CODE
Document Type and Number:
Japanese Patent JPS608903
Kind Code:
A
Abstract:
PURPOSE:To reduce remarkably the number of signal lines by sending out a discriminating code, and thereafter, transferring successively a binary code of 4-bit for displaying the contents of decimal each digit of a data, in parallel at every decimal each digit. CONSTITUTION:With regard to a data of a control parameter, etc., for instance, in case when a decimal number of 6789 is transferred, first of all, a discriminating code for making an object to be controlled discriminate what the data is sent out together with a strobe signal. Subsequently, a binary code of six for displaying the contents of 1,000 digits is sent out together with a strobe signal. Thereafter, a binary code of seven for displaying the contents of 100 digits is sent out together with a strobe signal. In the same way, a binary code for displaying the contents of a digit of ten and a digit of one is transferred successively together with a strobe signal. A microprocessor of a controlled system OBJ selects a corresponding output port by discriminating code, also executes a series/parallel conversion to decimal each digit from a controlling circuit CONT, restores it to a decimal number, and outputs it to a selected output port.
