Many appllications would benefit from the availability of large-capakcity content addressable memories (CAM's). However, while RAM'S, EEPROM's, and other memory types achieve ever-increasing per-chip bit counts, CAM's show little promise of following suit, due primarily to an inherent difficulty in implementing two-dimensional decoding. The serialized(More)
A novel single-chip shared buffer ATM switch architecture is presented, in which a Content Addressable Memory (CAM) is used to control access to the shared buffer RAM, in place of a linked list mechanism. Switch operation is explained in detail, and performance is compared to that of a Linked List switch. Memory capacity requirements are decreased, and cell(More)
Space switches suffer from external blocking because of output port contention. We review contention resolution methods used to avoid external blocking, and choose a solution based on ring reservation, resulting in an elegant and efficient mechanism requiring only nearest-neighbor communications. In addition to external blocking, space switches suffer from(More)
— Performance studies, linking ATM switch capabilities to physical limitations imposed by integrated circuit technology , have been scarce. This paper explores trends in circuit capabilities, and makes projections toward the 0.25-m technologies that will be available to all switch designers in the year 2000. The limits imposed by circuit technology are(More)
