Development of Low Power ISDB-T One-Segment Decoder by Mobile Multi-Media Engine SoC (S1G)

TOSHIBA has developed mobile multi-media engine SoC, we call as S1G, which can realize low power ISDB-T one-segment decode in 42mW for eight months short period of time. Since MPEG2 TS (transport stream) de-multiplexing, AAC decoding and H.264 decoding should be simultaneously processed in ISDB-T one-segment decode, two TOSHIBA MeP (media embedded processor) processors and one DSP and hardware blocks are used effectively with pipeline operation in this LSI. Although it is generally considered that dedicated hardware accelerator should be used to realize low power operation for ISDB-T one-segment decode, TOSHBA succeeded in developing low power ISDB-T one-segment decoder using maximum software resources.
