1 INTRODUCTION
1.1 OVERVIEW
To maintain our lead in advanced and highly integrated PC compatible computers,
DSP Design have released a very highly integrated, high performance processor
board compliant with the PC/104-Plus V1.1 specification. The board has been
specially designed to allow low power operation.
This processor card is fitted with the National Semiconductor Geode GX1 high
integration processor chip set, which operates at up to 300MHz. The Geode GX1 is a
Pentium-class processor, with MMX instruction set capability. The Geode GX1
incorporates a high-performance graphics controller and audio processor. The chip
set integrates many of the functions commonly found in core logic chips on PC
motherboards and provides a number of power saving features. Both ISA bus and
PCI bus interfaces are provided.
The consequence of using the Geode GX1 chip set is that an extremely high
performance PC compatible computer can be implemented in a very small form
factor.
The TP400 is the first processor board from DSP Design that complies with the
PC/104-Plus standard. The PC/104-Plus standard adds a PCI bus interface to the
PC/104 standard, thus allowing the use of high-performance PCI expansion boards
while retaining the small size and rugged construction of the PC/104 bus boards. The
PCI bus connector is a 120-pin connector on the edge of the PCB opposite the
PC/104 connectors.
The board supports up to 256M bytes of high-speed SDRAM. It also features the
standard PC compatible floppy and IDE disk interfaces, serial ports, parallel port,
keyboard interface, PS/2 mouse port and the standard PC speaker. The powerful
graphics controller in the Geode GX1 can drive both CRT and flat panel displays, and
a SoundBlaster-compatible sound system is also implemented in the Geode GX1.
Two USB ports, a 10/100Base-T Ethernet interface and an A/D converter are also
provided.
The TP400 is a single board PC/104-Plus compatible computer that can operate as a
stand-alone module or can be used in a system consisting of a number of other
PC/104 or PC/104-Plus modules.
The standard TP400 boards are provided with Flash File System software, which
converts the on-board 2M byte flash chip into a solid-state read/write disk drive. Up to
8M bytes of Flash memory can be fitted, subject to a minimum order quantity.
A range of other PC/104 boards is available from DSP Design. Various designs
include the TP300, An earlier version of the TP400 with 10base-T Ethernet, and the
TB486, a highly integrated low-power single board computer. A wide range of I/O
boards is available. Contact DSP Design for up-to-date information on other products
in our range.
The TP400 provides connectors with the same pin assignments as other DSP Design
processor boards, for easy upgrading.
