Abstract(in English) | This paper describes a heterogeneous multi-core processor (HMCP) architecture which integrates general purpose processors (CPU) and accelerators (ACC) to achieve high-performance as well as low-power consumption for SoCs of embedded systems. Memory architecture of CPUs and ACCs were unified to improve programming and compiling efficiency. For preliminary evaluation of the HMCP architecture, AAC-LC stereo audio encoding is parallelized on a heterogeneous multi-core having homogeneous processor cores and dynamic reconfigurable processor (DRP) accelerator cores. The performance evaluation shows that 54x AAC encoding is achieved on the chip with two CPUs at 600 MHz and two DRPs at 300 MHz, which realizes encoding of a whole CD in 1-2 minutes. |
