StrongARM-based embedded Linux SBC drives two displays

Jan 31, 2001 — by LinuxDevices Staff — from the LinuxDevices Archive

New York, NY; LinuxWorld — (press release excerpt) — Applied Data Systems (ADS) today introduced the “Tandem”, a “two-headed” single board computer (SBC) system, available with embedded Linux. The Tandem is one of the first multi-display systems running embedded Linux on the Intel StrongARM SA-1110 processor. It features two LCD's working off of one 32-bit StrongARM processor, with two independent applications working simultaneously.

Two MediaQ MQ200 Graphics Controllers drive two (up to 24 bit color) XGA sized displays, with two 2MB SDRAM frame buffers. Dual LVDS drivers for LCD data transmission in the unit now extend the distance the displays can be from the computer, allowing a distance of over 20 feet from the panel to the receivers. The Tandem can run two separate speakers coordinated with each display.

The Tandem also features a comprehensive I/O package. The Intel StrongARM SA-1111 processor companion chip provides a USB Bus Master with a four port Hub, facilitating peripheral communications. Ethernet 10bT, CAN and a temperature probe interface for VEE Compensation are all on-board. User-selectable options provide up to 32 digital I/O's and 12 analog inputs, and a keypad scan support for up to two 4 x 4 keypads.

The system is based on a 206 MHz, 32-bit StrongARM RISC processor, which can deliver 235 MIPS at just 450 mW power dissipation. The system is configurable with up to 32 MB of program memory /frame buffer DRAM, to 32 MB of flash memory, 128 KB of EPROM boot memory, 1 PCMCIA slot, 3 serial ports, CAN, an onboard codec with speaker and microphone support, an Ethernet port, a video interface to XGA, an LCD controller, a RTC, and an on-board 8-bit microcontroller that offers user-selectable options from 32 digital I/O's, 12 analog inputs, and 2 PWMs.

The Tandem is currently available, at pricing which starts in the $400's per unit.
