Abstract
Novel 3D-NoC architecture has been designed by expanding the impression of lossless compression of data. The proposed design shows remarkable results in terms of power efficiency and network throughput. In this scheme, proposed for 3D-NoC, the data to be transmitted is compressed on the transmitting side, so that the data packet is reduced before transmitting. And at the receiver, the original data is restored by decompressing the encoded data. Golomb-Rice algorithm is utilized to develop and implement the hardware encoder and decoder (Codec). The result is evaluated for both unicast and multicast routing. The improvement in power efficiency and throughput for proposed 3D-NoC (unicast) is 9,25 % and 17,61 % respectively. In similar, the improvement in power efficiency and throughput for proposed 3D-NoC (multicast) is 8,65 % and 14,66 % respectively. Further, from the result we observed that the improvement variation is higher for smaller bandwidth, which means the proposed 3D-NoC works well in case of narrow bandwidth.
