Pico-ITX board gets dual-core processor

Nov 9, 2011 — by Jonathan Angel — from the LinuxDevices Archive — 11 views

Via Technologies announced a Pico-ITX board featuring a dual-core Eden X2 processor and optional PCI Express expansion. The Epia-P900 offers gigabit Ethernet, two SATA ports, seven USB 2.0 ports, and support for HDMI, VGA, and LVDS displays, the company says.

Via touts its new Epia-P900 as offering the "industry's smallest commercialized form factor to feature multi-processing capabilities." While we haven't checked out that claim, the 3.9 x 2.8 inch (10 x 7.2cm) Pico-ITX board indeed offers a dual-core CPU, the company's 1.0GHz Eden X2.

When it announced this processor in March, Via promoted it with no ifs, ands, or buts as "the industry's lowest-power dual-core processor." However, the company still hasn't quantified the chip's power consumption, as far as we're aware, nor have we seen third-party reviews of any Eden X2-based devices.

In any case, Via's Epia-P900 takes advantage of the fact that the Eden X2 is pin-to-pin compatible with its earlier Eden, C7, and Nano E-Series. It's an evolutionary device with a layout that's almost identical to the Epia-830 that was announced last December with the E-Series. (It also bears a strong resemblance to the earlier Epia-P820 and Epia-P720, for that matter.)

Like the Epia-P930, the Epia-P900 uses the VX900H chipset. Promoted for its ability to provide 1080p video playback "without incurring a heavy CPU load," this 31 x 31mm chip accelerates H.264, MPEG-4/AVC, MPEG-2, VC-1, WMV-HD, AVS, Blu-ray, and "advanced browser streamed video technologies," Via says.

According to Via, the VX900H's ChromotionHD 2.0 video engine is also said to provide motion compensation, transform, de-blocking, and AVS support. Integrated display capabilities include a dedicated CRT interface, an LVDS transmitter, a multiplexed display interface for DisplayPort and HDMI, and a 12-bit digital video output port (DVP) for an external HMDI/LVDS/DVI transmitter.

Via leverages these capabilities on the Epia-P900 by providing an HDMI port on the board's coastline, along with pin headers for both VGA and LVDS. As shown above, there are other headers carrying USB, serial, PS/2, and audio signals, and the board also includes two SATA ports.

The Epia-P900 ships with a separate carrier board (the P830-A) that snaps firmly onto its headers, preserving access to the resident HDMI port. As pictured above, this device adds real-world VGA and gigabit Ethernet ports, along with two Type A USB 2.0 connectors, according to Via.

Although Via didn't mention the fact, we're guessing the Epia-P900 is also compatible with another accessory that was announced alongside the earlier Epia-P830. Pictured below, this is a daughterboard that snaps onto the main board's proprietary PCI Express expansion (2 x 1-lane) connector and — at the cost of increasing overall footprint by an unspecified amount — delivers two Mini PCI Express expansion slots.

We suppose the Epia-P900 is also — without the Mini PCI Express expansion, at least — physically compatible with an enclosure that was touted as turning the prior Epia-P820 into a complete, compact "industrial-class" PC. One side of the Amos-3001, pictured below left, provides access to the Pico-ITX board's coastline, while the other side (below right) adds two more USB 2.0 ports, audio I/O, a GPIO port, and dual serial ports.

According to Via, the Amos-3001 has room internally for an IDE-interfaced flash drive. Alternatively, an add-on expansion chassis (pictured above right) provides room for a 2.5-inch SATA hard disk drive. Without the expansion chassis, the Amos-3001 measures just 5.9 x 4.25 x 1.81 inches (15 x 10.8 x 4.6cm), making it 20 percent more compact than the previously released Amos-3000, the company says.
