Rugged box-PC runs Linux on new quad-core Via Eden CPU

Aug 13, 2015 — by Rick Lehrbaum — 4,530 views

Via announced a compact, rugged, fanless box-PC based on an unpublicized 1.2GHz quad-core Eden X4 CPU, with numerous I/O and wireless options, including 3G.

At 151 x 110 x 48mm, the “AMOS-3005” is nearly identical in size and appearance to the company’s earlier AMOS-820 system. But unlike the earlier model’s i.MX6 ARM core, the AMOS-3005 is built with Via’s new 1.2GHz Eden X4 CPU, a quad-core spin of the x86-compatible Eden X2. The AMOS-3005 supports a fairly wide operating temperature of 0 to 60°C, and can be powered from a 9 to 36V DC input.

The AMOS-3005’s design pairs the Eden X4 CPU with the Via VX11 MSP (Media System Processor) chipset, which provides GPU, memory controller, and I/O expansion hub functions (see farther below). Standard interfaces include HDMI and VGA display outputs (usable simultaneously), and two helpings each of USB 3.0 ports, lockable USB 2.0 ports, Gigabit Ethernet ports, and COM ports. Other expansion interfaces include 8-bit GPIO, an mSATA socket, a SIM slot, and mini-PCIe expansion. An SODIMM socket supports DDR3 SDRAM of up to 8GB.

Internally, the AMOS-3005 consists of a two-board sandwich consisting of what appears to be a pico-ITX SBC on the bottom, acting as the motherboard, along with an I/O-oriented daughterboard that plugs into its top.

Although Via has yet to post a product page or provide a datasheet for the Eden X4, we presume the X4 is essentially a scaled-up Eden X2 chip. The latter is minted in 40nm process technology and integrates two 64-bit, superscalar Via Eden cores on a single die. Interestingly, Via says the Eden X2 is “fully pin-to-pin compatible” with its C7, Nano E-Series, Nano X2 E-Series, and QuadCore E-Series processors, so we presume this compatibility extends to the Eden X4 as well.

Via’s VX11 “chipset” integrates a collection of core system functions within a single component. As shown in the diagram above, these include a memory controller for up to 16GB DDR3 SDRAM, a Via Chromotion 5.0 video engine, and numerous I/O and expansion interfaces. Multimedia I/O capabilities of the VX11 are said to include VGA, DisplayPort, HDMI, and LVDS interfaces with resolutions as high as 2560 x 1600 pixels, a video input port, and HD audio. There are also two SATA ports, up to three USB 3.0 and six USB 2.0 ports, and six PCI Express lanes. Not all the VX11’s capabilities are exploited in the AMOS-3005, however.

The AMOS-3005’s rugged metal enclosure features removable front and rear face plates, and supports wall, DIN Rail, and VESA mounting options.
