Fujitsu launches digital HDTV SoC
Fujitsu has launched the MB86H70, a digital HDTV system-on-chip (SoC) that integrates a video-processing engine and a multi-decoder that decodes MPEG-2 and H.264 video compression formats.
A picture-quality adjustment tool allows the picture parameters to be optimised easily via a graphical user interface (GUI) The integration of the video-processing engine together with the multi-decoder allows the use of common memory consisting of two 16-bit external memories

Fujitsu launches low pin-count microcontrollers
Fujitsu Microelectronics Europe (FME) has launched the MB95200 low pin-count series.
This reduces TV manufacturers' costs and development time for both design and manufacturing.
The MB86H70 incorporates the high-performance ARM1176JZF-S processor, featuring an integrated memory management unit (MMU), a floating point co-processor, ARM's Jazelle technology and thumb instruction set extensions for compact code.
The ARM11 provides all the processing power needed to enable a wide range of middleware software.

Prototyping kit for the ARM1176JZF-S enables "first-shot full operation" of engineering samples and further shortening of the development lead time.
Consumer memory boosts bandwidth
Device provides performance equivalent to two DDR2 SDRAMs with 16bit I/O, while requiring about 1W less power consumption.
The video processing engine has a hybrid filter that automatically adjusts filter strength by separate areas on the screen.
It distinguishes between the contours of each object and other areas on the picture and distinctly accentuates the contour to produce greater sharpness, while removing any noticeable noise from other areas.
The active grey-scale control automatically adjusts grey-scale (degree of brightness) in each scene.
It automatically selects optimised grey-scale for various video scenes, for example where fine differences in brightness are required, or when there are large differences in brightness within a scene, thereby enabling a wide variety of images to be optimally displayed.
Real 3-D colour control enables free control of the colour range and desired level of colour correction.
With Fujitsu's method that uses a 3-D colour space, very precise colour adjustment of a particular area is possible without influencing colours in other areas.
Other functions necessary to display HD video on a TV screen are included, such as motion-adaptive de-interlacing, which reduces jagged edges that can be caused by diagonal lines, as well as a scalar that enlarges and reduces HD images.
The MB86H70 includes full HD MPEG-2 and H.264 decoders, supporting current SD MPEG-2 broadcasts used widely in Europe and other regions, and next-generation HD broadcasts using H.264.
Audio decoders, necessary for HD broadcasts in Europe such as Dolby Digital, Dolby Digital Plus and HE-AAC, are also included.
By simply connecting two 16-bit-wide DDR2 SDRAM667 external memory chips as working memory to this digital HDTV SoC, the chip becomes fully functional, including CPU-based system control and digital-video decoding. Request a free brochure from Fujitsu Microelectronics Europe ...
