Kernel

Phoenix-RTOS is based on the written from scratch dedicated microkernel and consists of about 20K lines of code (LoC). Microkernel is responsible for:

• memory management

• thread and process management

• inter-thread communication and synchronization

• basic application interface implementation (syscalls)

Kernel is divided into five subsystems.

• hal - hardware abstraction layer

• lib - common routines

• vm - virtual memory management

• proc - process and thread management

• test - internal tests for kernel subsystems

The source code of the kernel could be obtained using the following command

git clone https://github.com/phoenix-rtos/phoenix-rtos-kernel.git

• HAL
• Processes and threads
• Memory management
• System calls
• Common routines
