NEC EMMA Mobile/EV SoC for Full HD Portable A/V Devices

NEC introduces the EMMA Mobile/EV new systems-on-chip (SoCs) designed to bring Full HD processing power to portable multimedia players and mobile tablet devices. The EMMA Mobile/EV  integrates ARM’s high-end Cortex-A9 CPU core and the POWERVR SGX 3D graphics core.

There are two versions, the EMMA Mobile/EV1 with one embedded Cortex-A9 CPU core and the EMMA Mobile/EV2 with two embedded Cortex-A9 CPU cores.


(1) Capable of HD format decoding in various formats

Through a dedicated A/V engine, EMMA Mobile/EV can decode H.264, MPEG2, MPEG4, VC-1 content up to full-HD (1920 x 1080 pixels) on portable devices.

(2) Incorporates built-in advanced interface with 3D graphics engine

The EMMA Mobile/EV2 chip integrates a high-performance POWERVR™ SGX™ 3D graphics core from Imagination Technologies Ltd., realizing 3D processing at 14.7 megapolygons per second and pixel-filtrate performance of 500 megapixels per second sustained under realistic operating conditions. This feature brings advanced effects that enable the creation of more realistic and compelling images.

(3) Reduced power consumption when playing back multimedia data

The new products incorporate various technologies such as automatic clock control, on-chip power switch and quick recovery (Note 1). Using those features, EMMA Mobile/EV reduces power consumption by up to 30 percent compared to EMMA Mobile 1, thereby contributing to longer battery life.

(4) Supports mobile DDR and DDR2 memory

The new products support mobile DDR and DDR2 as the main memory. System designers can choose either mobile DDR with low power consumption, or apply DDR2 to develop non-portable devices at low cost.
