We have presented an optimal on-chip buffer allocation and buffer insertion methodology which uses stochastic models of the architecture. This methodology uses finite buffer space and presents a method to distribute this finite space in an optimal fashion. Such a methodology is useful in managing the scarce buffer resources available on chip as compared to network based data communication which can have large buffer space. The methodology also uses Continuous Time Markov Decision Processes CTMDPs. The modeling of this problem in terms of a CTMDP framework lead to a nonlinear formulation due to usage of bridges in the bus architecture. We present a methodology to split the problem into several smaller, though linear systems and we then solve these subsystems.
