2 WE865-DUAL architecture
2.1 Hardware
WE865-DUAL WiFi module is connected and communicates with GE863-PRO³ through an SDIO
interface. For further hardware information please refer to [1] , [2] , [5] and [6]
2.2 Software
Studying Linux Operating System and Linux WiFi Software Framework is important to better
understand how WE865-DUAL can be configured and controlled.
Below you can find a high level description of Linux OS Architecture and the different software layers
involved in WE865-DUAL control.
2.2.1 Linux OS overview
The kernel is the central part of the GNU/Linux operating system: its main task is to manage system’s
resources in order to make the hardware and the software to communicate. A kernel usually deals
with process management (including inter-process communication), memory management and device
management.
The Linux kernel belongs to the family of Unix-like operating system kernel; created in 1991, it has
been developed in the years by a huge number of contributors worldwide, becoming one of the most
common and versatile kernel for embedded systems.
Below there is a picture representing, from a high level perspective, the architecture of a GNU/Linux
operating system.
