| Abstract(in English) | This paper proposes a local memory management scheme for an automatic parallelizing compiler to realize effective use of a limited size of local memory. After the loop aligned decomposition and task scheduling considering data locality and parallelism, the compiler allocates data to the local memory effectively using the task scheduling result. This paper evaluates the proposed scheme on RP2 multicore for consumer electronics which has 8 SH4A processor cores. Each core integrates 32KB of local data memory and 64KB of distributed shared memory. As the results, the proposed scheme using 8 processors gives us about 6.20 times speedup for MPEG2 encoding program, 7.25 times speedup for AAC encoding program and 7.64 times speedup for susan against the sequential execution. |
