Abstract

PURPOSE: To evade the access competition without raising the input speed of a buffer memory higher than an input circuit speed by providing a buffer memory in correspondence to an output circuit so as to divide it into banks on the share of the number of input circuits, and connecting the input circuit to the buffer memory through a switch every time the transfer request of a packet is issued.
CONSTITUTION: If packets PKi and PKj requesting transmission to the same output circuit OUTK (K<n) comes in from the input circuits INi and INj, the packets PKi and PKj are transferred to the banks BMi and BMj of the buffer memory belonging to the output circuit OUTK through a bus in a switch SW set by a decoder part DEC. Accordingly, in order to evade the access competition to the buffer memory or merely access competition multifunction is provided in correspondence to the input circuit, whereby the acceleration of an input to the buffer memory caused by connecting input and output sides through a bus multiplexed in terms of time division can be avoided.
