Abstract

PURPOSE:To make a preferential processing possible to improve the use efficiency of a data buffer, by storing communication data in the data buffer designated by the communication order from the transmission-side processor and by processing this data in accordance with communication purposes. CONSTITUTION:A control device 30 for communication between processors is provided with data buffers 60-80 which are adapted to transmission data different in communication purpose, respectively, and the communication order from transmission-side processors 11-1n and 21-2m is analyzed by a data buffer controller 50, and one data buffer corresponding to the communication purpose out of data buffers 60-80 is selected by this analysis, and transmission data from transmission-side processors 11-1n and 21-2m are stored temporarily. When transmission data is stored in some of buffers 60-80, this transmission data is taken out and is transmitted to receiving-side processors 11-1n and 21-2m designated by the communication order. Consequently, transmission data requiring a severe real time processing is processed preferentially, and the use efficiency of data buffers is improved.
