VIA VX855 media system processor offers hardware H.264 video acceleration
More users of netbooks, PMPs and handsets may be tuning into mobile TV thanks to VIA Technologies' new VIA VX855 media system processor (MSP). The VX855 offers a low-power, all-in-one chipset for small and mobile PC systems.
"The VIA VX855 opens up exciting opportunities for several PC segments, particularly the mini-notebook category that will now be able to offer true 1080p HD video playback," said Richard Brown, VP of marketing for VIA Technologies.
Microsoft Windows 7 ready, the VIA VX855 MSP offers support for full hardware acceleration of video standards including H.264, MPEG-2/4, VC-1 and WMV9, significantly reducing processor workload and power consumption.
Compatible with the ultra-compact VIA Nano, VIA C7 and VIA Eden processor families, the VIA VX855 MSP integrates all its features into a 27mm by 27mm single-chip package that saves almost half the silicon real estate compared with competing twin-chip core logic implementations. This miniaturization lets it run fanlessly within a tiny 2.3W power envelope, enabling smaller, lighter and more portable systems.
The VIA VX855 MSP integrates a high-performance DDR2 memory controller, a 400/800MHz FSB processor interface and extensive I/O capabilities (such as 6 x USB 2.0, SDIO, UART, SPI, LPC and SMBus). Support for the integrated VIA Chrome9 HCM graphics processor, HD audio controller and a host of display interfaces in its built-in LVDS transmitter, CMOS LCD and CRT interfaces permits more flexible multimedia playback options.
A high-frequency 2-D/3-D graphic engine powers advanced graphics. Image processing supports hardware decode acceleration for leading video standards. In addition, the image processor supports three audio streams of up to eight channels each, with 32-bit sample depth and sample rates up to 192kHz.
