Matsushita Electric Industrial, best known for its Panasonic brand, has recently developed a new-generation of its “UniPhier” LSI system that integrates new AV data compression/decompression (codec) technology. The company started mass-production of the new 250 million transistor chip this month on a 45nm process.
The UniPhier system is already widely used in many Panasonic digital AV devices, though the updated LSI adds an AV codec that responds to the next-generation image data compression standard, such as H.264, ideal for handling high-definition images.
Matsushita says that the chip features multi-decoding technology that enables two 1080p (1920X1080) high-definition (HD) screens to be processed simultaneously, and a high image quality encoding technology to compress 1080p HD images to a one third to half the size of conventional methods.
The additional circuitry required to process high-definition streams, which posed manufacturing challenges on the 65nm level, was more easily achieved at 45nm. Additionally, using the 45nm process reduced the device’s overall power requirements and heat output.
Matsushita is the latest to announce LSI technology using a 45nm semiconductor process. Earlier this week, Fujitsu revealed its own 45nm LSI for mobile applications.
