作者在提出位流水计算方法的基础上,已经将这种计算方法运用于实现超快速付立叶变换。本文研究超快速位流水付立叶变换采用多相时钟来提出工作频率。文中选写了进行相加(或相减)和求补的波形式。从公式分析得出相加结果和节拍时钟脉冲定位的定量关系。分析究研表明,利用S档的加法器和寄存器进行设计,工作频率可以提高到15兆赫;采用F档和S档寄存器混合设计,而加法器仍用S档器件,工作频率可达20
Based on the proposed bit-flow calculation method, the author has applied this method to realize ultra-fast Fourier transform. In this paper, ultra-fast bit-stream Fourier transform Fourier transform multi-phase clock to propose the working frequency. The text chosen to write the addition (or subtraction) and the complement of the wave form. From the formula analysis, the quantitative relationship between the addition result and the beat clock pulse positioning is obtained. Analysis shows that the use of S file adder and register design, the working frequency can be increased to 15 MHz; F file and S file register mixed design, and the adder still S file device, the operating frequency up to 20
