OFFSET AUTONOMOUS INPUT/OUTPUT CONTROLLER FOR ALLOCATING TIME SLOTS FOR INSTRUCTIONS ACCORDING TO TYPE OF INSTRUCTIONS AND IDENTIFYING SOURCE OF THE INSTRUCTION

An input/output controller interacts with a central processing unit of a computer which communicates with peripheral electronic equipment. The link with the central processor unit is produced with an input serial line and at least one output serial line. It receives instructions of a first type from the central processing unit and instructions of at least a second kind which are stored in the memory external to the central processing unit. These are processed using a sequencer device which allocates time slots to the instructions according to their type. This device is especially useful in the field of avionics and flight management systems.
