====== GECKO3main ======
{{ :gecko3:gecko3logo.png?400|}}
The core of the GECKO3 Project is the GECKO3main module which can be used as a general purpose System-­on­-Chip (SoC) platform for hardware/software co­-designs. The GECKO3main contains a very large 1 to 4 million gate Xilinx FPGA for application specific designs. The main board contains also large dynamic memory (128 MB) and flash memory banks (32 MB), USB 2.0 and 100 Mbit/s LAN interfaces.

For example a 32 bit RISC processors soft core ([[http://en.wikipedia.org/wiki/OpenRISC|OpenRISC]], [[http://en.wikipedia.org/wiki/Microblaze|Microblaze]] or similar) with closely coupled hardware blocks for high­-speed hardware ­algorithms and an embedded operating system ([[http://en.wikipedia.org/wiki/UClinux|uClinux]], [[http://en.wikipedia.org/wiki/ECos|eCos]] or similar) can be integrated together in the FPGA chip on the GECKO3main board.

===== Standards =====
This page covers the technical standards and conventions used in the GECKO3 system. Some of these standards are common and just re-used in this project. The rest is defined by the GECKO3 project to ensure compatibility between the various modules.

===== System bus =====
The [[gecko3:system_bus:start|GECKO3 system bus]] page describes the GECKO3 system bus (IO1 and IO2).

===== Templates =====
The [[gecko3:template:start|Templates and Libraries]] page provides the developer with a template overview for a better work-flow.


===== GECKO3 combination matrix =====

Not all modules can be combined. Which combinations are possible is shown in the matrix underneath.
