Title:
BUFFER CONTROL SYSTEM FOR COMMUNICATION CONTROLLER
Document Type and Number:
Japanese Patent JPH0281153
Kind Code:
A
Abstract:

PURPOSE: To prevent the deterioration of the transmission efficiency by using a reception buffer of a communication controller to perform the temporary reception in the case a reception buffer of a shared memory has no margin.

CONSTITUTION: The data received via a communication circuit 40 is given to a process part 12 of a communication controller 10 and then stored as it is in a reception buffer 22 of a shared memory as long as the buffer 22 has a margin. This operation is repeated. The part 12 stores the received data temporarily into a reception buffer 13 at the time point when it is known that the buffer 22 has no margin. This operation is repeated hereafter. Thus a receiving process is through. In such a constitution, a retransmitting procedure or a reception suppressing procedure is not required and therefore the transmission efficiency is improved.
