# Memory management
|
|
# Description:
|
|
# - tlsf
|
|
# A dynamic, fragmentation-resistant allocator designed for real-time and embedded systems
|
|
# (e.g., RTOS, MCUs with moderate RAM). It balances speed, memory utilization, and low fragmentation.
|
|
#
|
|
# - lwmem
|
|
# A lightweight, MCU-optimized allocator (developed for embedded systems) that prioritizes minimal
|
|
# resource usage (RAM/ROM) while supporting basic dynamic allocation/deallocation.
|
|
#
|
|
# - bump
|
|
# The simplest and fastest memory allocator, often called a "linear allocator" or "stack allocator"
|
|
# (though not to be confused with the program stack). It manages a single contiguous block of
|
|
# memory (a memory pool) with a single pointer (offset) that "bumps forward" to allocate memory.
|
|
#
|
|
# - other
|
|
# Other memory allocation algorithms, you can implement your own memory allocation algorithm.
|
|
|
|
# If you want to use dynamic memory allocation algorithm, you can consider it as an option
