提出了用于开发可合成FFT核的方法。这些都是基于一个模块化的方法,其中参数化的换向器和处理器块级联,以实现在许多重要的FFT信号流图所需的计算。此外,还展示了如何使用数字串行数据组织来生产能够沿着降低存储需求并提供100%处理器利用率的系统。该方法已被用于创建生成器,用于FFT核心的自动合成,这些核心可在广泛的硅技术中移植。由此产生的芯片设计与使用手动方法创建的芯片设计相比具有竞争力,但设计时间显著减少。
Methods are presented for developing synthesizable FFT cores. These are based on a modular approach in which parameterized commutator and processor blocks are cascaded to implement the computations required in many important FFT signal flow graphs. In addition, it is shown how the use of a digital serial data organization can be used to produce systems that offer 100% processor utilization along with reductions in storage requirements. The approach has been used to create generators for the automated synthesis of FFT cores that are portable across a broad range of silicon technologies. Resulting chip designs are competitive with ones created using manual methods but with significant reductions in design times.
