在TMS320VC54x DSP上实现DIT实序列基2FFT的两种方法

Two Radix-2 FFT Algorithms According to DIT Using the TMS320C54x Fixed-point DSP

简要地探讨了按时间抽取(DIT)实序列基2(Radix-2)FFT运算的原理,以及在TI公司的TMS320C54x定点DSP上以汇编语言实现之的两种方法,并对定点DSP实现FFT运算的不足之处作出了说明。

The principle of Radix-2 FFT arithmetic according to DIT, and two algorithms for accomplishment using TMS320C54x fixed-point DSP in the assembly language are introduced. The shortage of Radix-2 FFT algorithms using fixed-point DSP is discussed.
