Version 1.38.00
Release date : 2014-02-14
Requirements
- µC/CPU V1.29.01 or more recent
New features & improvements
- Memory segments: Added possibility to create multiple memory segments at run-time and to allocate memory blocks from them.
- Dynamic memory pools: Added new memory pools that can allocate blocks from a given memory segment and for which it is not necessary to specify a maximum number of blocks.
- New macros created to toggle bit and to read, write and encode values from a bit mask.
API Changes
- Changes to
lib_cfg.hLIB_MEM_CFG_ALLOC_EN removed. Set LIB_MEM_CFG_HEAP_SIZE to 0 to disable heap allocation features.LIB_MEM_CFG_HEAP_PADDING_ALIGN was added to specify a default padding alignment for any buffer allocated from the heap.LIB_MEM_CFG_DBG_INFO_EN was added and allows to track memory allocations.
- New functions added to
lib_mem.h/lib_mem.c
Mem_SegCreate()Mem_SegClr()Mem_SegAlloc()Mem_SegAllocExt()Mem_SegAllocHW()Mem_SegRemSizeGet()Mem_OutputUsage()Mem_DynPoolCreate()Mem_DynPoolCreateHW()Mem_DynPoolBlkGet()Mem_DynPoolBlkFree()Mem_DynPoolBlkNbrAvailGet()
- New macros added to
lib_def.hDEF_BIT_TOGGLE()DEF_BIT_FIELD_RD()DEF_BIT_FIELD_ENC()DEF_BIT_FIELD_WR()
Mem_PoolBlkGetAtIx() function removed.
µC/FS versions prior to 4.07.00 are not compatible with this version of µC/LIB. |
Deprecated features
Memory heap allocation and static memory pool features are now deprecated and will be removed in a future version of µC/LIB.
This includes the following functions:
Mem_HeapAlloc()Mem_HeapGetSizeRem()Mem_PoolCreate()Mem_PoolClr()Mem_PoolBlkGet()Mem_PoolBlkFree()Mem_PoolBlkGetNbrAvail()
Heap allocation features are replaced by Memory Segment allocation features and Memory Pool features are replaced by the Dynamic Memory Pool features.
