Abstract

Upcoming reconfigurable Multiprocessor Systems-on-Chip (MPSoCs) present new challenges for the design and early estimation of technology requirements due to their runtime adaptive hardware architecture. The usage of simulators offers capabilities to overcome these issues. In this article, MPSoCSim, a SystemC simulator for Network-on-Chip (NoC) based MPSoCs is extended to support the simulation of reconfigurable MPSoCs. Processors, such as ARM and MicroBlaze, and peripheral models used within the virtual platform are provided by Imperas/OVP and attached to the NoC. Moreover, traffic generators are available to analyze the system. The virtual platform currently supports mesh topology with wormhole switching and several routing algorithms such as XY-, a minimal West-First algorithm, and an adaptive West-First algorithm. Amongst the impact of routing algorithms regarding performance, reconfiguration processes can be examined using the presented simulator. A mechanism for dynamic partial reconfiguration is implemented that is oriented towards the reconfiguration scheme on real FPGA platforms. It includes the simulation of the undefined behavior of the hardware region during reconfiguration and allows the adjustment of parameters. During runtime, dynamic partial reconfiguration interfaces are used to connect the Network-on-Chip infrastructure with reconfigurable regions. The configuration access ports can be modeled by the controller for the dynamic partial reconfiguration in form of an application programming interface. An additional SystemC component enables the readout of simulation time from within the application. For evaluation of the simulator timing and power consumption of the simulated hardware are estimated and compared with a real hardware implementation on a Xilinx Zynq FPGA. The comparison shows that the simulator improves the development of reconfigurable MPSoCs by early estimation of system requirements. The power estimations show a maximum deviation of 9mW at 1.9W total power consumption.
