Heterogeneous multicore architectures, integrating several kinds of accelerator cores in addition to general purpose processor cores, have been attracting much attention to realize high performance with low power consumption. To attain effective high performance, high application software productivity, and low power consumption on heterogeneous multicores, cooperation between an architecture and a parallelizing compiler is important. This paper proposes a compiler cooperative heterogeneous multicore architecture and parallelizing compilation scheme for it. Performance of the proposed scheme is evaluated on the heterogeneous multicore integrating Hitachi and Renesas' SH4A processor cores and Hitachi's FE-GA accelerator cores, using an MP3 encoder. The heterogeneous multicore gives us 14.34 times speedup with two SH4As and two FE-GAs, and 26.05 times speedup with four SH4As and four FE-GAs against sequential execution with a single SH4A. The cooperation between the heterogeneous multicore architecture and the parallelizing compiler enables to achieve high performance in a short development period. |
