This paper introduces a novel heterogeneous shared memory multiprocessor architecture based on a reconfigurable processor and a standard RISC processor. The work aims at increasing further the computational density of a reconfigurable device by the integration of the reconfigurable hardware into a heterogeneous multi-core architecture. Though a RISC processor has a lower inner computational density than a reconfigurable processor, this work demonstrates that coupling a reconfigurable core to a RISC core leads to a computational density increase by a factor of up to 1.7times on signal processing applications. Moreover, this approach also achieves up to 37% energy savings on the same applications. The multi-core SoC architecture was implemented in 0.13mum technology, achieving a 166MHz clock frequency with an average 340mW power consumption
