由于LSI的迅速发展,在信号处理中,使用专用数字信号计算机已经成为一种明显的趋势。特别是自1965年Cooley-Tukey发明了快速傅里叶变换FFT算法以来,专用的FFT计算机在七十年代初期就在市场出售了。最近,Intel等公司,又研制了单片AN ALOG计算机,Intel2920等,以适应数字滤波等方面的需要。从方法上来说,除了FFT之外,数论变换NTT也受到了普遍重视,相应的专用数字信号计算机也在研究之中。信号计算机的应用领域是很宽广的。在语言处理与地震数据处理中,从一开始就采用了数字
Due to the rapid development of LSI, the use of a dedicated digital signal computer has become a clear trend in signal processing. Especially since Cooley-Tukey invented the Fast Fourier Transform (FFT) algorithm in 1965, dedicated FFT computers were sold in the market in the early seventies. Recently, Intel and other companies, but also developed a single AN ALOG computer, Intel2920, etc., to meet the needs of digital filtering. Methodically speaking, in addition to the FFT, the number-theoretic transformation NTT has also received universal attention, and corresponding dedicated digital signal computers are under study. The application of signal computer is very broad. In language processing and seismic data processing, numbers are used from the beginning
