Process Management

[massout]

The builds created so far were to provide the underlying hardware abstraction for debugging.

In order for the created structure to be an operating system, the process control structure that performs the transition between processes, which is the minimum requirement, must be integrated.

An integration as described in the A first preemptive kernel on ARM Cortex-M3 was considered, but the ARM Cortex-M4 processor was used in this link. The ARM Cortex A53 processor on the Raspberry Pi 3A+ has a different architecture and there is a difference in data transfer mnemonics. For this reason, the method in this link is planned to be integrated into the A53 processor.
