Renesas Electronics has announced the availability of system-on-chips that achieve playback of audio and video data in a single chip for portable audio-visual devices, including portable multimedia players, electronic book readers and network TVs.
The SoCs are EMMA Mobile EV series products that incorporate the latest ARM Cortex A9 high-performance CPU and integrate on a single chip the functions necessary for MPEG2, MPEG4, and H.264 HDTV (1920× 1080pixels) video playback.
The SoCs feature a reduced package size by approximately one-third from the company's existing 16×16mm to a 9×9mm package. Using system-in-package technology, the company included optimal-size DRAM in the same package. These features contribute to miniaturisation of the systems. The features also obviates the need for designing a high-speed interface with an external DRAM and contributes to easier end-product circuit-board design. The company also developed the EMMA Mobile EV0-S SoCs, that do not include DRAM.
In addition to supporting system miniaturisation, this also obviates the need for designing a high-speed interface with an external DRAM and contributes to easier end-product circuit-board design.
