Abstract
A system for accelerating an RNN network including: a first cache, which is used for outputting Wto Wor Wto Win parallel in N paths in a cyclic switching manner, and the degree of parallelism is k; a second cache, which is used for outputting xor hin the cyclic switching manner; a vector multiplication circuit, which is used for, by using N groups of multiplication arrays, respectively calculating Wxto Wx, or respectively calculating Whto Wh; an addition circuit, which is used for calculating Wx+Wh+bto Wx+Wh+b; an activation circuit, which is used for performing an activation operation according to an output of the addition circuit; a state updating circuit, which is used for acquiring c, calculating cand h, updating c, and sending hto the second cache; a bias data cache; a vector cache; and a cell state cache.
