A Highly Optimized Processor For Compressed Audio Application
Y. Shibuya, Ichiro Tamitani · 1998
An optimized audio processor for compressed audio application has been developed. The processor employs a dual-processor architecture. One of the two processors is a 26-bit fixed-point signal processor for high quality audio signal processing. The other is a 16-bit data processor optimized for compressed bit stream. In compressed audio applications, not only signal processing such as FFT, but also data comparison and bit manipulation is necessary.
