With the progress of technology, more and more intellectual properties (IPs) can be integrated into one single chip. The performance bottleneck has shifted from the computation in individual IPs to the communication among IPs. A Network-on-Chip (NoC) was proposed to provide high scalability and parallel communication. An ASIC-implemented NoC lacks flexibility and has a high non-recurring engineering (NRE) cost. As an alternative, we can implement an NoC in a Field Programmable Gate Arrays (FPGA). In addition, FPGA devices can support dynamic partial reconfiguration such that the hardware circuits can be configured into an FPGA at run time when necessary, without interfering hardware circuits that are already running. Such an FPGA-based NoC, namely reconfigurable NoC (RNoC), is more flexible and the NRE cost of FPGA-based NoC is also much lower than that of an ASIC-based NoC. Because of dynamic partial reconfiguration, there are several issues in the RNoC design. We focus on how communication between hardware and software can be made efficient for RNoC. We implement three communication architectures for RNoC namely single output FIFO-based architecture, multiple output FIFO-based architecture, and shared memory-based architecture. The average communication memory overhead is less on the single output FIFO-based architecture and the shared memory-based architecture than on the multiple output FIFO-based architecture when the lifetime interval is smaller than 0.5. In the performance analysis, some real applications are applied. Real application examples show that performance of the multiple output FIFO-based architecture is more efficient by as much as 1.789 times than the performance of the single output FIFO-based architecture. The performance of the shared memory-based architecture is more efficient by as much as 1.748 times than the performance of the single output FIFO-based architecture.
