| Abstract: | The features of Stratix series device EP1S40 of Ahera Co. and its programming and configuration are presented. The FIR filtering-based digital orthogonal transformation is implemented by reusing IP core and VHDL design of peripheral circuit. The I and Q quantities are successfully extracted, greatly enhancing the speed of digital signal processing. |
