Abstract(in Japanese) (See Japanese page)
Abstract(in English) A new approach to implement queues for address controlling of a shared-buffering ATM Switch is presented.We combined a self-timed FIFO with a search circuit that finds the earliest entry for each output port.Using this architecture,queues provided for each output port can be effectively realized by a single FIFO.The delay priority and multicasting are supported without doubling the number of the queues.If we load this new FIFO with ATM cells instead of address,the FIFO itself can work as an ATM Switch. Evaluation chip was fabricated using 0.5-μm CMOS process technolog y.Inter-stage transfer speed over 500 MHz and cycle time over 125 MHz were obtained.
