Accelerate with the following instruction set：
int16x8_t sum_vec = vdupq_n_s16（0）； //8 16-bit integers ser 0
vgetq_lane_s16 //Get the specified location data by SIMD
int16x8_t w_vec = vld1q_s16(weight); //Read in eight data at the same time by SIMD
int16x8_t mul_v = vmulq_s16 //multiply in eight data at the same time by SIMD
vaddq_s16 //add eight data at the same time by SIMD
