This paper addresses a novel coarse grain dynamic reconfigurable computing system, called DReAC-2, design and hardware implement. A whole DReAC-2 system integrates a Nios II processor, which manages the whole reconfigurable system, and a dynamic reconfigurable coprocessor, which comprises of an 8x8 processing node array designed for high regularity, high computation-intensive tasks. Hardware prototype of DReAC-2 has been implemented on the ALTERA STRATIX II EP2S180 development board. According to task's nature, MIMD computing array can select either parallel-pipelined pattern or array-parallel pattern to gain the better performance. The experiment results show that DReAC-2 achieves much higher 10 similar to 100x factor than NIOS II processors, and 2x similar to 4x factors and higher precision than some others reconfigurable processors(1).
