| Abstract(in English) | Although the digital hearing aids with the high functionality of digital signal processor (DSP) becomes widely used, its battery life is limited to only a few days. In order to solve this problem, we have proposed the low power bit serial multiply-accumulator (BS-MAC) by using a ring oscillator. In BS-MAC which calculates sequentially per bit, however, it was difficult to satisfy the performance for necessary of a digital filter. Therefore, we focus on unnecessary operations by zero multiplication, and improve the calculation time and power consumption by curtailing these operations in BS-MAC. In additon, we design FIR filter as an application of the BS-MAC, and confirm its operation through implementation on FPGA. |
