Abstract
Methods and apparatus for supporting programmable burst management schemes on pipelined buses. The apparatus includes a plurality of bus masters (masters), configured in a plurality of clusters, and a plurality of target sub-groups. Each target sub-group includes one or more shared resource targets. A scalable chassis infrastructure is used to interconnect the targets with the clusters using a crossbar interconnect configuration including pipelined command, and data buses. The interconnect includes sub-group multiplexers for each sub-group and sub-group selection multiplexers coupled to each cluster. A two-stage arbiter, operatively coupled to the targets, sub-group multiplexers, and sub-group selection multiplexers, is employed to arbitrate transaction requests issued from the masters to the targets and manage transactions. The two-stage arbiter includes a provision for supporting programmable burst management, wherein selected sub-groups can be tuned for handling short or long burst traffic.
