Board Uses FFT To Form Beams

For sonar, radar, communications, and instrumentation applications, ICS2200 board uses the Sharp Microelectronics Inc. 50 MHz Butterfly BDSP9124 Fast Fourier Transform processor to perform multi-channel finite impulse response (FIR) filtering and decimation, complex demodulation, replica correlation, complex beamforming and inverse beamforming. This processor's architecture maintains the sequential order of data by channel as up to 4096 high bandwidth channels are input to the board. The board leverages the FFT chip's architecture with four specially designed hardware sequencers that control the operation of the board and manage the data flow. The board can sustain computing power of up to 640 MOPS using one VMEbus slot.
