Tiny board aims TI SoC at embedded imaging apps

Jul 3, 2013 — by Rick Lehrbaum 1,761 views

FossilShale Embedded Technologies announced a SODIMM-style CPU module based on a Texas Instruments DM385 digital media processor with a 1GHz ARM Cortex-A8 core. The DM385-SOM primarily targets embedded imaging tasks, such as surveillance and medical imaging devices, and is supported with a carrier board, several I/O adapters, and customized Linux and Android software stacks.

According to FossilShale, the 1GHz TI DM385 SoC can deliver 2000 MIPS performance. Additionally, the TI chip’s integrated video accelerators are capable of real-time H.264 video encoding/decoding at resolutions up to 1080p and 60fps frame rates.

The DM385-SOM module is implemented in a standard 82 x 57mm 244-pin SODIMM format, with a non-standard pinout. The board’s 244-pin edgecard connector exposes all of the TI SoC’s key interfaces, for use with external carrier boards, says the company.


FossilShale suggests a long list of potential applications for the DM385-SOM, including: IP cameras, IP video phones and video conferencing devices; digital signage and remote media displays; media players; network projectors; portable medical imaging and monitoring devices; remote media displays; camcorders and digital scanners; and video-enabled access control panels.

TI DM385 SoC‘s built-in graphics capabilities include hardware accelerators for image resizing, face detection, and HDVICP v2 encode, decode, and transcode operations, plus support for H.264 BP/MP/HP, MPEG2, VC1, MPEG4 SP/ASP, JPEG/MJPEG media formats, says FossilShale.

Key features of the DM385-SOM include:

  • Processor — TI DM385 SoC, based on 1GHz ARM Cortex CPU core
  • Memory:
    • 1GB DDR3 RAM
    • 512MB NAND flash
    • 1x microSD/MMC connector
  • A/V interfaces:

FossilShale also offers a Carrier Board for the DM385-SOM, for which the following functions and connectors are listed:

  • 2x Ethernet
  • 2x SATA
  • 1x USB Host port
  • 1x mini-PCIe socket
  • Camera Input connector
  • 30-bit Digital Video out and 16-bit Digital Video in
  • Other — GPIO; I2C; SPI

The company is also offering three accessory boards for use with the DM385-SOM, including a 802.11b/g/n WiFi board, an LCD board that supports 5-, 7- or 10-inch LCDs with optional touchpanels, and a camera module that provides a MIPI interface supporting 5/10/12 megapixel sensors.

The FS-DM385-SOM can be ordered starting this month, although delivery and pricing details are not currently listed. For further information, visit FossilShale’s system-on-module page.
