Panasonic has developed a new UniPhier system LSI for smart TVs.
Panasonic's new system LSI will enable it to make high performance and high resolution Smart TVs with considerably lower power consumption, accelerating the spread of wide screen smart TVs around the world.
To improve performance and user interface, smart TVs require powerful software processing capability as they support various applications on the Internet. Achieving these improvements has called for a system LSI that has a high quality AV processor and a high speed CPU on a single chip.
Panasonic's new chip will open the way for a new generation of smart TVs that allow users to simultaneously enjoy two TV broadcasting channels, as well as Internet-based content and applications in high-resolution at the same time. In addition, the new chip is able to reduce the power consumption of, and the number of components used, in smart TVs, which will help drive smart TVs to spread in the global market.
The chip includes the following features:
• The new system LSI adopts a new architecture comprising of Panasonic's UniPhier processor with a proven track record in high quality processing of audio and visual content and a general-purpose high speed dual CPU which has high performance for network applications to realise a high performance and high resolution Smart TVs.
• Adopting the industry's fastest 1.4-GHz dual core CPU (ARM Cortex-A9 Dual), it can achieve fast, stress-free and smooth operation in network applications.
• A high-performance 3D graphics circuit supporting full HD resolution is essential for smart TVs. Integrating such a 3D graphics circuit and audio and video codec, the new system LSI has all the functions required for smart TVs on a single chip. As a result, it enables delivery of exciting images by combining graphics and video. Furthermore, the new chip enables to cut power consumption by about 40%, compared to prior Panasonic chips.
The following technologies have made this chip possible:
• UniPhier new architectures, which enables parallel, simultaneous operation of the UniPhier processor's TV signal processing that is in real time treatable of AV contents and the dual-core CPU's handling of wide range open-source software.
• Circuit design technology for high-speed processors, enabling implementation of a dual-core CPU and high-capacity cache memory, as well as operation at 1.4-GHz clock frequency.
• One-chip system LSI integration technology that combines UniPhier processor and high speed dual-core CPU, high-performance 3D graphics circuitry with unified memory architecture which achieving efficient data transfers between shared external memory.
