This is safer because the previous code assumed that the start and end VMAs of .data and .bss were word-aligned, which is not always the case, so the initialization code could write data outside these sections. The ROM functions support any address boundary. This is faster because the ROM functions are ultra optimized, using realignment and the LDM/STM instructions, which is much better than the previous simple loops of single word accesses. This is smaller because the ROM functions don't require to add any code to the target device other than simple function calls. This makes the code simpler and more maintainable because standard functions are not reimplemented and no assembly is used. Note that this is also faster and smaller than the corresponding functions from the standard string library. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau.dev@gmail.com> |

The Contiki Operating System
Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.
Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
