Title:
DATA TRANSFER SYSTEM
Document Type and Number:
Japanese Patent JPH01201763
Kind Code:
A
Abstract:
PURPOSE:To receive a large capacity of data at intervals of a prescribed time by providing a buffer memory in a slave station and collectively transferring data from a main station to the slave station. CONSTITUTION:A main station information processing part 2 writes communication data stored in a memory 1 into a large capacity buffer 10 through a data bus at the intervals of the prescribed time, and informs the slave station of the transfer completion of data. A slave station information processing part 3 receives the signal and sequentially reads data from the large capacity buffer memory 10 one by one. Said part 3 processes data and stores processed data in a memory 9. Since the main station information processing part 2 is occupied only at the time of writing into the large capacity buffer 10, queuing does not occur in the processing of the main station.
