|---|---|---|---|---|
| memory_pool_elements | 8192,8192,8192,8192,8192,2048 | cString | Specifies the number of elements to be created in each assigned memory block. | |
| memory_pool_mode | 1 | tInt32 | (0) disabled: The memory service will no longer manage the memory blocks. Instead the default new and delete operators will be used to allocate and deallocate the requested memory.(1) active: The Memory Manger allocates and frees the memory using the settings from memory_pool_sizes and memory_pool_elements.(2) statistic: The memory service runs in statistic mode. After a running configuration has been terminated, information on memory consumption are displayed on console view. | Value List: disabled = 0 active = 1 statistic = 2 |
| memory_pool_sizes | 16,32,128,512,4096,65536 | cString | Specifies the size in bytes of each managed memory block. The memory manager allows users to define up to 16 different sizes of memory block. It is recommended to list the size in ascending order. Anyway they will be sorted automatically if the order is not correct. |

When ADTF requests a block of memory, the memory manager allocates that block out of the larger blocks it has received from the operating system. Memory blocks that are no longer required will be recycled for reuse to conserve operating system memory resources. It is the responsibility of the programmer to decide when memory can be reused.
