Design of High-Speed VOQ Management Scheme for High Performance Cell/Packet Switch
고성능 셀/패킷 스위치를 위한 고속 VOQ 관리기 설계
Abstract
This paper presents the design of high-speed virtual output queue(VOQ) management scheme for high performance cell/packet switch, which has a serial cross bar structure. The proposed VOQ management scheme has been designed for wire-speed routing with a pipelined buffer management. It provides the tolerance of requests and grants data transmission latency between the VOQ manager and central arbiter using a new request control method that is based on a high-speed shifter. The designed VOQ manager has been implemented in a field programmable gate array chip with a 77MHz operating frequency, a 900-pin fine ball grid array package, and 16
