The VP (vector processor), designed and accomplished by ourselves, is an advanced processor, with BDSP9124/9320 as its main component. It can process 1M samples of data, and processing precision approaches the floating point processor. It could be applied for SAR (synthetic aperture radar) and other fields. The CSA (chirp scaling algorithm) is suitable for the VP calculation. Using the two-dimensional FFT to perform the CSA, the VP can remove corner turning memory and reduce processing overhead. Using the a large radix to complete the FFT, it can also reduce the processing time. The VP can produce a satisfactory image with high resolution, in right and squint side looking strip mapping
