Directories and Files
cpu_a.asm contains the assembly language functions to implement the code to disable
and enable CPU interrupts, count leading zeros (if the CPU supports that instruction)
and other CPU specific functions that can only be written in assembly language. This
file could also contain code to enable caches, setup MPUs and MMU and more. The
functions provided in this file are accessible from C.
cpu_c.c contains C code of functions that are specific to the specific CPU architecture
but written in C for portability. As a general rule, if a function can be written in C then
it should, unless there are significant performance benefits by writing it in assembly
language.
3-5 μC/LIB, PORTABLE LIBRARY FUNCTIONS
μC/LIB consists of library functions that are meant to be highly portable and not tied to any
specific compiler. This was done to facilitate third party certification of Micriμm products.
