Abstract

PURPOSE: To prevent the stagnation of processing for the buffer request section, by assigning the buffer longer in the usage time used with other request section at the buffer managing section when no vacant buffer is avilable, in buffer request.
CONSTITUTION: The buffer request section accesses the buffer memory 4 via the buffer managing section 3. When the buffer request section 1-2 delivers the buffer request signal R2 to the managing section 3, if all the buffers 4A, 4B... of the memory 4 are in use, the managing section 3 compulsively returns the buffer used earliest among the buffers 4A, 4B... and assigns it to the request section 1-2. Further, the item of the table is rewritten to 1-2 and the count value of timer is written in the said item, and further, as the signal A2, it is written in the address indication register 2-2. Thus, when the buffer request is present, since the buffer can be assigned without fail, the stagnation of processing of the request section can be avoided.
