Abstract:

This paper studied and accomplished a high speed vector processor. The main component of the processor is a special Digital Signal Processing (DSP) chip set BDSP9124/9320, which is produced by Butterfly DSP Inc. The processor could be applied to Synthetic Aperture Radar (SAR) and other fields which require real-time calculating FFT, correlation, convolution, and other vector processing.
