Abstract :
The AT&T DSP32 chip, a programmable digital signal processor with a 32-b floating-point arithmetic unit and a 16-MHz operation rate, can be used for computing the discrete Fourier, cosine, and Hartley transforms. A single common structure is developed to ensure both high performance and a high degree of flexibility. Some real-time implementation issues are discussed
