Abstract
The communication control apparatus can suppress the maximum cell intervals and further enables the simultaneous transmit decision processing for a plurality of the virtual lines. A communication control apparatus used for asynchronous communication executed by setting a transmit enable time at which data can be transmitted to each of a plurality of virtual lines, and by deciding the virtual lines having transmissible data on the basis of the transmit enable times comprises: a time comparing section (1) for comparing the transmit enable times set to a plurality of the virtual lines having transmissible data, respectively with transmit decision time at the same time, to generate comparison result signals; a flag holding section (3) for holding the comparison result signals generated by the time comparing means for each of a plurality of the virtual lines, and erasing the held comparison result signal of a predetermined virtual line in response to a clear signal; and a priority deciding section (5), when a plurality of data-transmissible comparison result signals are held in the flag holding means at the same transmit decision time, for deciding priority sequence of the virtual lines…
