Abstract(in English) | Hyperdimensional computing (HDC) can perform various cognitive tasks efficiently by mapping data to hyperdimensional vectors consisting of thousands to tens of thousands of dimensions. On the other hand, since the main operations of HDC, Bind, Permutation and Bound, require several cycles in the computing unit, it is not necessarily efficient to perform HDC on CPU platform. In this paper, we propose a programmable accelerator specialized for HDC. Our accelerator can execute various tasks at high speed and with low power consumption by cooperating with the CPU. Furthermore, by making it possible to freely select three operations per cycle, our accelerator enables to support any HDC encoding method. Through evaluation experiments with the ARM-v7 processor, we show that the above operations can be accelerated by a maximum of 169 times. We also confirmed that our accelerator can improve the energy-delay product up to 13,469 times in the training of handwritten character recognition task. |
