ARM11 module supports videoconferencing

Feb 19, 2009 — by Eric Brown — from the LinuxDevices Archive — 8 views

Embedian is shipping a Linux-ready ARM11 MXM computer-on-module (COM) and evaluation kit. The MXM-6410 COM is equipped with a Samsung S3C6410 system-on-chip (SoC) that weds a ARM1176JZF-S core clocked to 667Mhz with a multimedia co-processor that can encode and decode MPEG4/H.263/H.264 and decode VC1, says Embedian.

The MXM-6410 targets multimedia-enabled embedded applications, including devices that require real-time videoconferencing, says Embedian. The module is based on a Samsung S3C6410 system-on-chip (SoC) with a ARM1176JZF-S core clocked up to 667MHz. This 65nm-fabricated SoC integrates a Multi Format Codec (MFC) co-processor that is said to support real-time videoconferencing, as well as TV-out, for both NTSC and PAL modes. In addition, the module is equipped with a JPEG codec, a 2D graphics accelerator, and a 3D graphics hardware accelerator that supports OpenGL-ES 1.1 and 2.0 rendering.

The Samsung SoC is supported by 128MB each of mDDR and NAND flash memory, says Embedian. A 242-pin MXM golden finger connector provides a wide variety of interfaces on the board. These are said to include TFT LCD, dual USB host interfaces, Ethernet, four RS232 interfaces, camera, CF, IDE, AC97 Audio, IIC, PWM, TV-out, and SPI.

Embedian launched its original MXM-7114 COM in November 2007. Its most recent MXM COMs — the MXM-8310 and MXM-8110 — were released last July, based on the Marvell PXA320 chip. Shortly before, a new organization called Qseven announced its own a multi-vendor COM spec that also uses an MXM connector. Formed by European COM module vendors Congatec, MSC Vertriebs, and Seco, and with 14 members total, Qseven launched the first version of its Qseven specification, calling for four mounting holes instead of Embedian's two, and a slightly larger 70 x 70mm size instead of Embedian's 66 x 50mm format. Qseven bills its format as being mobile-device oriented and “legacy-free,” offering support for new formats like SDIO, while spurning some older I/O technologies.

Specifications for the MXM-6410 are said to include:
