A heterogeneous multiprocessor on a chip has been designed and implemented. It consists of 2 CPUs and 2 DRPs (Dynamic Reconfigurable Processors). The design of DRP was intended to achieve high-performance in a small area to be integrated on a SoC for embedded systems. Memory architecture of CPUs and DRPs were unified to improve programming and compiling efficiency. 54times AAC-LC stereo encoding has been enabled with 2 DRPs at 300 MHz and 2 CPUs at 600 MHz.
