Matsushita to use 45nm chips in Blu-rays in November

Matsushita Electrical Industries announced it will start shipping Diga-brand Blu-ray optical disc recorders with 45nm chips in November under the Panasonic label. Panasonic revealed Tuesday it is launching the optical disc recorder, initially only in Japan.

The Japan-based company said that the latest version of its UniPhier chips will be the first made in a 45nm process technology to reach the mass volume consumer market. Intel is also planning to ship processors made on a 45nm process in November.

Matsushita developed the 45nm process in its own fab in conjunction with Renesas Technology. The process uses 193nm immersion lithography, stress-induced mobility-enhanced transistors, low-k dielectrics and design-for-manufacturability technologies.

The UniPhier, short for UNIversal Platform for High Quality Image Enhancing Revolution, digital consumer electronics integration platform uses the MPEG-4 AVC/H.264 codec. The UniPhier LSI integrates 250 million transistors on chip yet is said to be very power efficient.

According to the company, using the device allowed it to manage to quadruple the recordable time for the same media compared with MPEG-2, a representative conventional codec for moving pictures, since the image compression can be performed at twice or three times the usual efficiency

In addition, the part uses multi decoding technology, which is capable of simultaneously processing two large screens of high picture quality and full-HD, and MPEG-4 AVC/H.264 encoding technology, which compresses a full-HD image into 1/2 to 1/3 its original size compared with the conventional technology.

Panasonic sees the UniPhier architecture as the basis in the future for a whole range of products, from media-oriented mobile phones to in-car entertainment systems.
