Class MDBuffers

java.lang.Object
  mapss.dif.mdsdf.mem.MDBuffers

public class MDBuffers
extends java.lang.Object

The class computes buffer information of the MDSDF graph. Given the MDSDFGraph and its corresponding single appearance schedule, this class computes buffer size and collects buffer access information.
