ASIC design of Gabor transform for speech processing

For speech processing applications such as speech coding or speech recognition, Gabor transform has been a more and more important tool to rid the speech signal of redundancy. A new ASIC design of Gabor transform for speech processing is presented in this paper. To implement the high-speed operation of Gabor transform, some special architectures are designed. The control part of the system can configure the arithmetic units to adapt to variant operation requirement such as input of different points and processing Gabor transform or inverse-Gabor transform. The design is implemented by using ASIC technology
