The FIFO buffer comprises a first logic module that receives m N-bit data portions from a switch fabric, the m N-bit data portions comprising one or more N-bit data words of one or more data packets. A plurality of one-port memories store the received data portions. Each one-port memory has a width W segmented into S portions of width W/S, where W/S is related to N. A second logic module provides one or more N-bit data words, from the one-port memories, corresponding to the received m N-bit data portions. In a sequence of clock cycles, the data portions are alternately transferred from corresponding segments of the one-port memories in a round-robin fashion, and, for each clock cycle, the second logic module constructs data out read from the one-port memories."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High speed packet FIFO output buffers for switch fabric with speedup","description":"Described embodiments provide a first-in, first-out (FIFO) buffer for packet switching in a crossbar switch with a speedup factor of m.
