| Abstract(in English) | SNACC (Scalable Neuro Accelerator Core with Cubic integration) is an accelerator for deep neural network, which can improve the performance by increasing the number of stacked chips with inductive coupling wireless through chip interface (TCI). The chip implementation and real chip evaluation of SNACC are introduced. It consists of four processing element cores which execute dedicated SIMD instructions, distributed memory modules for storing weight data, and TCI. The real chip evaluation by using Renesas Electronics’ 65nm SOTB (Silicon On Thin Box) CMOS technology appears that a simple CNN LeNet works at 50MHz for all layers with 0.90V supply voltage. The power consumption is less than 10mW. The performance can be enhanced by the forward body biasing about 15% in exchange for about 2mW leakage increasing. Also, SNACC achieved more than 20 times high performance to a MIPS R3000 compatible embedded processor. |
