Abstract

PURPOSE:To obtain a circuit which does not require the design change for external conditions or the like and controls the high-speed data transfer with simple constitution, by providing specific external condition synchronizing means, processing order monitoring means, and cycle holding means. CONSTITUTION:A data transfer controlling circuit connected to a central processor or the like through a high-speed line 108 is provided with an external condition synchronizing circuit 115 which synchronizes analysis conditions for transmission/receiving or the like by a start command 119 from the external, a processing order monitoring circuit 113 where the processing instruction sequence for condition analysis and data analysis corresponding to the output of the circuit 115 is held in an ROM, and a cycle holding circuit 114 which secures the number of cycles required for each processing. Said ciruit 113 consists of, for example, an ROM10 where a program for line control is stored, an external condition synchronizing circuit 9, and synchronizing circuits 8 and 11.
