Wide-screen 8.5in TFT LCD suits a wide range of applications from mobile computing to medical or industrial equipment.
A custom carrier board, designed to suit the exact mechanical layout of the system, bears the connectivity with the outside world, and peripheral silicon - handling the display interface and so on.
A standard processing module, which carries the CPU and chipset and most of the core processing and interface control plugs in to this carrier board.
The carrier board can have its size, connectors and physical features laid out to exactly suit the inside of the end product.
A range of 2.5in HDD-sized system modules is available - featuring low-energy-consumption Geode, higher-power Via Eden and Transmeta Crusoe processors at present.
This SOM philosophy also allows for several levels of end product with differing levels of PC horsepower, but all with the same physical PC card layout.
An example might be an EPOS terminal with an entry-level SOM plus DSTN colour screen and a high-end sister version with larger TFT screen, more PC power and extra functionality.
According to Trident, this semicustom approach allows designers to save space by omitting peripheral support and features that they don't require, and to save considerable tooling or plastics cost by positioning the main board connectors in the optimum configuration to suit the requirements of the packaging or the user.
Several of-the-shelf evaluation carrier board styles exist to help designers finalise their target hardware before commissioning their own custom carrier board.
Trident is Evalue's design and support partner in the UK and has a full range of flat-panel displays compatible with Evalue's SBCs and system on module products.
For high volume designs, Evalue and Trident offer the advantages of full custom design, and at the other end of the spectrum, a wide range of standard single board computing options is available with processors from Geode up to Pentium IV.
