The “128K FFT Streaming IP” implements the Windowing and the FFT of complex arrays of 128K samples. An input stream of complex samples is delivered to the board through a Gigabit Ethernet (UDP). The stream can be processed in blocks of 32K (or 64K or 128K) by windowing and FFT. The results (block floating point) are delivered from the board on the Gigabit Ethernet.
The Core will be pre tested in Stratix II NIOS development board equipped with Gigabit PHY board.
