Document Type and Number:
Japanese Patent JP2763394
Kind Code:
B2
Abstract:
PURPOSE:To check the adequacy of a received data with a simple device by making a window correspondent to a storage area of a RAM, writing information to check the adequacy of a data to an address corresponding to a transmission state variable V(S) and a check state variable V(A) and reading the information of the address corresponding to a reception sequence number N(R) from a transmission destination. CONSTITUTION:The controller is provided with a RAM 1, a selector 2, counters 10,11, and a comparator 12, and a window to indicate a sequence number forming a modulo circulation system of transmission data in the order of transmission is made correspondent to a storage area of a RAM 1 of 1-bit*N-words, the information to check the adequacy of the data is written to an address corresponding to a transmission state variable V(S) and a check state variable V(A) and the information in an address corresponding to a reception sequence number N(R) in a signal from a transmission destination is read. Thus, it is not required to make case classification in details by means of the software for the discrimination of the adequacy of the data. Thus, the adequacy of a received data is checked immediately after the reception of the data with a simple device.
