Leo aims at European navigation applications
Fujitsu Microelectronics Europe is releasing its Leo FR-V (Fujitsu RISC-VLIW) chip, based on the FR-V architecture announced last year.
They include two-dimensional and three-dimensional (2D/3D) graphics accelerators with a 24bit/pixel display controller.
The camera YUV interface is supported by both CCD and CMOS camera modules (up to 2Mpixel), which can be attached to the MMPs simultaneously, with one active at a time.
These have the ability to interface between two LCDs, enabling users to display multiple images simultaneously on two separate screens.

A new series of dual phase-locked loop (PLL) frequency synthesisers designed by Fujitsu feature extremely low power consumption, fast lock times and ultrasmall packaging.
Next generation terrestrial DVB demodulator
The next generation single-chip COFDM DVB-T compliant demodulator, developed by Fujitsu Microelectronics Europe is now available in volume quantities.
The devices feature a flexible CPU interface that enables easy connection to existing baseband or application processors.
Other features include the ability to display three windows, and to mix multiple visual images using alpha blending (transparency).
The devices also provide hardware support for image scaling and rotation, and also include bitblt and texture mapping features.
When the internal clock operates at 13.5MHz, and the MPEG-4 codec is functioning, the device consumes just 13mW (codec core), a much lower power consumption than any other such device.
It is also possible to operate the MPEG-4 codec with the internal clock at 54MHz, allowing not only low power consumption but also high performance.
To eliminate the need for external memory, the MB86V00 device incorporates 64Mbit of SDRAM as a system-in-package.
To minimise power requirements, sophisticated clock-gating techniques shut down logical functions when they are not needed or not in use.
The advanced power management hardware is managed by Fujitsu's firmware which monitors various chip activities and throttles the clocks accordingly.
"Adding one of these MMPs to the central processor typically found in handheld devices enables the device to handle sophisticated graphics with ultra-low power consumption", said Dirk Weinsziehr, Senior Director Marketing for Fujitsu Microelectronics Europe.
"With the proliferation of features in mobile phones and PDAs, there is a growing need for a specialised application processor to handle multimedia functions without sacrificing battery life.
Our new devices meet those requirements".
The design expertise for the new MMP series comes from Fujitsu's technical leadership in graphics display controller devices, which were developed in collaboration with major automobile manufacturers and are now installed in more than 60% of the dashboard navigation systems sold worldwide.
Fujitsu's graphics display controllers provide multiple layers, special line-drawing functions, numerous windows with resizing and transparency for overlapping and video input.
"The mobile media processor combines Fujitsu's proven graphics processing with MPEG-4 and JPEG hardware compression in a single chip, enabling high-quality images to be delivered to small-form-factor displays", said Takeshi Fuse, FME's Business Unit Director for Mobile.
"Our MMPs now meet the complex and intensive processing required for video and graphics in mobile products, with a minimum of power".
When mounted in a 3G mobile phone, the MMP captures images through one of the two camera ports and then compresses the images using JPEG for still shots, or MPEG-4 for moving pictures.
The processor will also render 2D graphics for maps, or 3D graphics for games and other forms of animation.
The MMP incorporates two LCD interfaces, so images can be displayed on either one or two LCD screens.
To ensure that all these functions perform optimally and do not interfere with each other, Fujitsu provides OS-independent driver software equipped with host processor support code.
The software performs power-management operations by monitoring I/O and macro block activity, and determines when to throttle the various clock domains up or down.
The optimised driver tools significantly reduce development time and increase device efficiency.
The MMPs support a pair of camera devices.
Built using Fujitsu's low-leakage 0.18-micron CMOS process, they are housed in 289-pin FBGA packages.
The MB86V00 device incorporates 64Mbit of SDRAM as a system-in-package, and mass production of both MB86V00 and MB86V01 will start in September. Request a free brochure from Fujitsu Microelectronics Europe ...
