Functional Overview

This section describes the major Poseidon subsystems.

Processor

Two processor options are available for the Poseidon board.

•

Low-power, fanless 1.0GHz VIA Eden ULV CPU

•

High-performance 2.0GHz VIA C7 CPU

North Bridge and South Bridge

The North and South bridge are integrated in the on-board VIA CX700 chip.

Memory

The board accommodates 512MB 

or 1GB 

of SDRAM system memory soldered on the board.  No expansion connector 

is 

provided for additional memory.

The board also includes flash memory for storage of BIOS and user programs.  Flash memory is accessible via the 
on-board ISA bus.

Video Features

Video circuitry is provided by the VIA CX700 chipset and includes,

•

Dual 200MHz 2D/3D graphics engines featuring dedicated 128-bit data paths for pixel data flow and 
texture/command access.

•

An integrated MPEG-2 decoder.

•

Dual independent display with separate frame buffers for CRT and flat panel displays.

Audio

The design provides AC97 audio support derived from the South Bridge chip.  The Via VT1612A CODEC provides 
audio processing.  Give special attention to design and routing to minimize noise on the audio I/O lines. 

Audio I/O includes,

•

Stereo line in.

•

Stereo line out.

•

Mono mic in.

•

Stereo internal line in.

The board includes audio power amplifier circuitry for stereo speaker output.  The amplifier circuit is powered by 
+5VDC from the board.  User DC control of volume is also provided, which overrides the software settings.

Ethernet

The board supports 10-/100-/1000BaseT (Gigabit) Ethernet.  Magnetics are included on the board so that a complete 
circuit is provided.
