<p>PURPOSE:To heighten the transmission efficiency of data by eliminating the need of the definition of an output destination at every packet when output data is transferred successively to the same output destination, by providing a crossbar function and a bus function. CONSTITUTION:A crossbar route deciding circuit 161 outputs packet route output signals 211 and 212 to decide a route at the time of performing a crossbar function operation by a timing signal from a timing input pin 131. A bus route deciding circuit 171 outputs lock route output signals 221 and 222 to decide the route at the time of performing a bus function operation by the timing signal from a timing input pin 131 and a route set signal from a route set input pin 141. A route selector 181 selects either the packet route output signal 211 or the lock route output signal 221 by a lock mode signal from a lock mode input pin 151, and outputs a selector output signal 201.</p> |
