To meet the increasing demand of large bandwidth and high throughput in modern radar system, we proposed a reconfigurable application specified processor (RASP) according to the feature of radar digital signal processing applications. RASP is a reconfigurable coprocessor based on hierarchical floating-point operation elements that is capable of executing a set of fundamental subalgorithms, take these subalgorithms as the minimal task node can improve the computational efficiency tremendously. The experimental results show that the processor performance exceeds TI state-of-the-art DSP by 1.05x to 3.22x. Our reconfigurable processor can be integrated into customizable radar systems, it was fabricated with TMSC 40nm CMOS process and has an area of 19.2mm2.
