Zusammenfassung:We developed a DSP for wireless base-band processing on handheld devices. The DSP is composed of a scalar CPU and a vector unit. The architecture of the vector unit inherits that of vector processors for super computers, and we customized it for embedded systems. We evaluated the processor using several programs. The evaluation showed that our DSP performs 40 times faster than scalar CPU. The peak performance is 12GOPS@250MHz.
