Abstract :
Consideration is given to the performance analysis of a RISC (reduced instruction set computer) machine (RISC/B) based on timed Petri net (TPN) models. The operation flow graph is created according to the RISC/B instruction execution patterns and the pipeline structures. A TPN is used to model the operation in the graph. A sequence of discrete-time Markov chains (DTMCs) is built from the TPN in the instruction execution path. The DTMC model is useful for the study of various design and analysis issues in processor architecture. The model has been validated by comparing the analytical results with those obtained from the RISC/B prototype machine. Bottlenecks in the prototype have been identified through the model and cache performance tradeoffs have been investigated from both the architectural and the organizational viewpoints
