Abstract :
Compression of digital audio signals has become increasingly more important with the advent of fast and inexpensive microprocessors and DSPs. Several compression schemes were developed. Most of them adopt the MDCT/IMDCT. This paper presents a FPGA implementation of a fast MDCT algorithm. An investigation of different approaches of implementation and usage of standard embedded FPGA elements for specific digital signal processing has been carried out. The two designs presented in this paper are suitable for real-time applications of multi-channel audio digital signal processing
