Operation Support Subsystem

The operation support subsystem drives and encapsulates the bottom-layer hardware,
providing support for other software systems on the upper layer. This subsystem
provides support for the running of the hardware, allocating resources for the hardware,
and provides the hardware-related interfaces for the upper-layer software. The operation
support subsystem relies on the ROS platform of the ZXR10, and it is composed of
system support, system control, version load control, BSP, and SSP. It can be further
divided into the operating system kernel, process scheduling, process communication,
timer management, and memory management modules. The functional block diagram
for the operation support subsystem is shown as follow:
