<p>PURPOSE: To provide a mediation method for accelerating switching in a large- scaled asynchronous transfer mode switch. CONSTITUTION: A cross bar system is adopted, and when two or more output requests turned to the same output port compete, request signals for indicating the output requests for the requests are NAND operated for the respective rows of a matrix with one-bit signals stored beforehand in a matrix shape, the result of the NAND operation is wired OR operated for the respective columns of the matrix and internal signals Q are obtained for the respective columns. It is detected that the order of the internal signals Q is in complimentary relation with the order relating to one row of the one-bit signals stored beforehand in the matrix shape and understanding signals are generated for the output request relating to the row of the equal order. A mediation process is executed at an extremely high speed because it is all performed on a hardware.</p> |
