If the architecture includes multiple, non-contiguous regions of
|
||
|
|
memory to allocate from, this specifies the number of memory regions
|
||
|
|
that the memory manager must handle and enables the API
|
||
|
|
mm_addregion(start, end);

config MM_SMALL

bool "Small memory model"

---help---
|
||
|
|
Each memory allocation has a small allocation overhead. The size
|
||
|
|
of that overhead is normally determined by the "width" of the
|
||
|
|
address support by the MCU. MCUs that support 16-bit addressability
|
||
|
|
have smaller overhead than devices that support 32-bit addressability.
|
||
|
|
However, there are many MCUs that support 32-bit addressability *but*
|
||
|
|
have internal SRAM of size less than or equal to 64Kb. In this case,
|
||
|
|
CONFIG_MM_SMALL can be defined so that those MCUs will also benefit
|
||
|
|
from the smaller, 16-bit-based allocation overhead.
