pplication-specific processors are used to obtain the efficiency of fixed-function application-specific integrated circuits and flexibility of software implementations on programmable processors. The efficiency is achieved by tailoring the processor architecture according to the requirements of the application while the flexibility is provided by the programmability. In this chapter, we introduce a hardware/software codesign environment for developing application-specific processors, which is using processor templates based on the transport-triggering paradigm, hence the name transport-triggered architecture (TTA). Fast Fourier transform (FFT) is used as an example application to illustrate the customization. Specific features of FFTs are discussed, and we show how those can be exploited in FFT implementations. We have customized a TTA processor for FFT, and its energy efficiency is compared against several other FFT implementations to prove the potential of the concept.
