Abstract :
Frequency analysis using the DFT, the DHT, the DCT or the DST is an obvious choice for signal processing domain. This paper describes the implementation of a DXT coprocessor of transform length ´8´ for the synchronous design in a 0.22 LM Flash-based FPGA device (ACTEL). The total dynamic power of 359.24 mW, with an operating frequency of 50 MHz and an operating voltage of 2.5 V is achieved. The paper presents the trade-offs involved in designing the architecture, the design for performance issues and the possibilities for future development.
