NoC performance parameters estimation at design stage

Nowadays different types of communication systems are used in designing of data transmission systems. Performance and operating characteristics of communication systems are crucial. System-on-chip (SoC) communication system can be built based on a bus, switch or network-on-chip (NoC). Type of communication system is selected according to user requirements for bandwidth, time delays, hardware cost of communication systems implementation and technology limitations. In this paper we consider the problem of different communication systems characteristics estimation. Formulas for average and maximum data transmission time calculation of different flows will be presented for different types of communication systems. Load estimation for each transfer point will be presented also. Proposed network calculator includes mechanisms based on the queuing systems to calculate the parameters of communication system. Attention will be paid to NoC communication system characteristics calculation.
