发明名称 LINE SCANNING SYSTEM
摘要 PURPOSE:To determine the most efficient scanning order in accordance with kinds of stored communication speed and the number of lines and use usable line addresses in order from the beginning without omission by making it possible to define freely the scanning order and the scanning range of lines. CONSTITUTION:An address register 2 holds logical line address of a line to which data on a register 1 is outputted, and a physical line address is used as it in the conventional method. An address register 3 holds the logical line address indicating a line set LS from which data set to a register 4 is inputted, and the physical line address is used there also in the conventional method. An address conversion memory 5 converts the logical line address to a physical line address to scan a line controlling memory (ICW) 9. An address conversion memory rewrite control circuit 6 updates conversion contents of the memory 5 on a basis of an instruction OUT from a program to facilitate scanning limitation and address substitution; and even if the line number is changed, contents of the address conversion memroy 5 are rewritten to cope with this change easily.
