新增RT_USING_MEMHEAP_AS_HEAP 功能,可以使用 memheap 作为系统默认的 memory heap 工具: 在building.py 中支持自动生成 Visual Studio 工程 新增SConsUI 图形界面工具 分支: 新增PPC405 分支 新增NXP LPC4330 分支 新增win32 的 simulator 分支 --完善对编译环境 Visual Studio 2005 及以上版本的支持 --支持...
当不需要再使用这些内存块时,需要释放回堆中供其他应用分配使用,否则会造成内存泄漏。 RTT为我们提供了三种动态内存堆的调度算法:小内存管理算法slab算法memheap管理算法静态内存池管理内存堆管理器非常灵活和方便,但是会产生以下两个问题:分配效率不高,在每次分配时,都要空闲内存块查找。 容易产生...

The original heap function will be turned off after memheap is turned on. Both can only be selected by turning RT_USING_MEMHEAP_AS_HEAP on or off.Working mechanism of memheap is shown in the figure below. First, add multiple blocks of memory to the memheap_item linked list to glue. The...
Using memheap, the user can "paste" multiple memory heaps together, letting them operate as if operating a memory heap. The concept of memory management will be explained in the "Memory Management" chapter. I/O Device Management RT-Thread uses I2C, SPI, USB, UART, etc., as peripheral ...
