'First' LSI chip for Blu-ray player debuts

EMMA3PF

NEC Electronics announced that it had developed the world's first single-chip LSI to integrate the main functions of Blu-ray disc players.

In June, NEC Electronics released the SCOMBO/UM2P, which has all of the front-end functions on one chip. In the past, NEC Electronics has released products designed to place the backend functions on one chip and this month, the company released the EMMA3P, which specializes in playback. The EMMA3PF has these two advanced system LSI on one chip, which will help reduce the size of future Blu-ray disc players.

Functionalities
The EMMA3PF features a single chip that has the required functions for a Blu-ray disc player. The EMMA3PF combines the front-end functions of the SCOMBO/UM2P (introduced by LEN in June) with the backend functions of the EMMA3P. This is the first time ever that the required functions for a Blu-ray disc player have been integrated into one chip. The chip has an analog circuit to process signals from the optical pickup, a decoding circuit for encoded video and audio and an HDMI to output video and audio.

The device also features a 50 percent reduction in package area. Unified memory architecture (UMA) integrates the chip, allowing the front-end and backend functions to share the external memory required for these functions. An on-board USB 2.0 host controller has also been included. The package area is 50 percent smaller than the combined area of the previous products, which reduces part costs and space requirements.

EMMA3PF supports Blu-ray disc specifications for video and audio playback. The device supports the codecs used by Blu-ray discs. Picture in picture playback of H.264/AVC, VC-1, MPEG2/1 and other video formats and the audio playback of Dolby TrueHD, DTS-HD and other formats are possible. Support is planned for the DivX format. The on-board Ethernet controller and digital rights management make it possible to download content via a network connection.

Moreover, the chip offers a multicore CPU and graphics accelerator. Player startup speed and operability are greatly improved by a 64bit 655DMIPS VR5500 CPU application processor, a 32bit 495DMIPS CPU by MIPS Technology, a vector graphics accelerator for graphic processing and a still-image decoder.

The EMMA3PF has the same LSI architecture as the EMMA and SCOMBO products, which means that users can still use applications developed for EMMA and SCOMBO products.

Sample shipments of EMMA3PF will begin in September. Monthly production is expected to be 1,000,000 units from Q4 08.
