Outline of Final Research Achievements

We developed a heterogeneous multicore architecture and its compiler flow, which enable flexible cooperation among CPUs, accelerator cores, and data transfer units, which is a kind of extended DMA controller, in a multicore chip. One of the main achievements in this research project is that a program parallelized by the developed compiler flow including LLVM backend for the accelerator core obtains 24.91x speedup on the heterogeneous multicore on an FPGA test bed, which is also developed in this research.
