Systems and methods for performing multi-message transaction based performance simulations of SoC IP cores within a Network on Chip (NoC) interconnect architecture by accurately imitating full SoC behavior are described. The example implementations involve simulations to evaluate and detect NoC behavior based on execution of multiple transactions at different rates / times / intervals, wherein each transaction can contain one or more messages, with each message being associated with a source agent and a destination agent. Each message can also be associated with multiple parameters such as rate, size, value, latency, among other like parameters that can be configured to indicate the execution of the transaction by a simulator to simulate a real-time scenario for generating performance reports for the NoC interconnect.

The invention relates to a wavelength-allocation-based three-dimensional optical on-chip network router communication system and method. The communication system employs a photoelectric mixing type 3D mesh network topological structure and a novel seven-port clog-free optical router capable of realizing multi-wavelength communication; and when the system is applied to a three-dimensional optical on-chip network, no wavelength conversion is needed. Because of utilization of the optical router, the consumed number of optical devices like micro ring resonators and waveguides and the like is reduced. Besides, according to the communication method, when a node of each layer sends out an optical signal, the employed wavelengths are identical; and optical signals with all wavelengths can be received at all layers, so that problems of severe network congestion, low link utilization rate, and limited expansibility due to utilization of single wavelength communication by the existing optical on-chip network architecture can be solved. Therefore, with the system and method, the network congestion probability can be reduced; the communication delay can be reduced; and the throughput capacity and network saturation point can be improved.
