摘要:快速傅立叶变换的应用领域非常广泛,其硬件实现方法多种多样,验证这些电路的正确性具有很强的实用价值。传统的电路正确性验证的方法是模拟,这种方法的主要缺点是随着参与运算的点数的增加,穷尽模拟全部输入情况所耗费的时间越来越长,甚至难以实现。而形式化方法使用纯数学手段证明电路的正确性,克服了传统方法的缺点。首先用重写系统给出了任意N=2M点的基2的流水式快速傅里叶变换处理机的形式化模型,然后给出它的正确性验证,探索了验证处理复数的复杂电路正确性的方法。
Fast Fourier Transform(FFr) has a wide range of usage, it also has many various ways of hardware implements. Simulation is a traditional way for hardware verifying,the main weakness of this method is that it is a hard work (sometimes it is impossible) to give all kinds of input that the circuit may have.On the contrast,formal methods can use pure mathematical methods to verify a circuit's properties.That is why exploring new ways to verify the correctness of FFT hardware circuits using formal method is important.This paper presents a formal model of Radix-2 FFT processor using rewriting system and verifies that it can process complex data properly.These explore a new way to verify complex circuit.
