System Architecture

At the heart of the BlackBerry 10 OS is the QNX Neutrino realtime operating system. The System Architecture guide accompanies the QNX Neutrino realtime OS and is intended for both application developers and end-users.

This guide describes the philosophy of QNX Neutrino and the architecture used to robustly implement the OS. It covers message-passing services, followed by the details of the microkernel, the process manager, resource managers, and other aspects of QNX Neutrino.

The following table may help you find information quickly:
