To overcome this, the NoC-based architecture has been proposed in the past decade.

The architecture consists of preprocessors, routers, network interfaces, and processing elements.

Various sizes, including 2 × 2, 4 × 4, and 8 × 8, with 256 points capability, of the NoC-based architecture have been implemented and verified on a Xilinx Virtex- 6 device and the TSMC 0.18-μm cell library. The core area of the 8 × 8 NoC architecture is 11,302.26 μm × 11,300.16 μm, equivalent to 8,099,544 gates. The average power consumption is 2693.4 mW at the operating frequency of 66 MHz.
