Example Summary

This application demonstrates shows the use of xdc.runtime.Memory module and different xdc.runtime.IHeap implementations to manage memory.

Example Usage

• Run the application, the two tasks that run will allocate memory from two different IHeap implementations and print their memory statuses to the console.

Application Design Details

• The application dynamically constructs two tasks, both tasks use xdc.runtime.Memory to allocate memory but use two different different IHeap implementations or heaps.

• The first task runs as task0Fxn uses ti.sysbios.heaps.HeapBuf to dynamically create its heap, task0Heap, because the allocations are of a fixed size.

• The second task run as task1Fxn uses ti.sysbios.heaps.HeapMem to dynamically construct its heap, task1Heap, as this task allocates variable block sizes. Both tasks print their heap status before allocations and after freeing the allocated memory.

The system heap is created statically using ti.sysbios.heaps.HeapMem and is plugged into xdc.runtime.memory as the defaultHeapInstance. Please see the corresponding configuration file memory.cfg for details.
