Decomposition Method for Burst Mode Asynchronous Controllers
Yong Li · 2009
A systematic and automated methodology was proposed for decomposing an asynchronous Burst Mode(BM)controller into smaller sub-controllers,where each resulting sub-controller is activated on a communication channel.The proposed approach consists of a new decomposition method,inter-controller Burst Mode state machine and inter-controller communication protocol.Furthermore,only a moderate amount of auxiliary hardware is required.Initial runtime results for Burst Mode controllers are promising.One of the largest BM benchmarks(dean-cache)was run using the Minimalist CAD tool.While the original controllers each timed out after 10 hours,the decomposition runs each completed in less than 88 seconds.One large complex controller(pscsi)was unable to complete while the decomposed run su-cceeded in under 54 seconds.
