현재 DACS1000 에서 사용되어 지고 있는 메모리의 양을 확인하는 문서이다. 일반적으로 컴파일시에 만들어지는 .map 파일을 보고 확인할 수 있다. 일반 에디터로 볼 수도 있지만, ST 에서 제공하는 비주얼 툴인 ST Visual Memory 를 사용해서 확인할 것이다.
우선 두가지 상황을 비교해서 확인할 것이다.
- DCU 에 연결할 때
- FLASH 에 연결할 때
두가지 상황은 엄연히 다르다. 일단 첫번째 경우에 생성되는 map 을 보자!!

위의 정보를 참조한 아래의 그림이다.
중간 중간에, 파란색은 빈 공간이다. 각 영역의 주소나 사이즈를 정해주는 파일은 config 디렉토리아래의 파일들과 include 파일들이다. 그 중에서 mb382_um.cfg 이다.
이제 각 영역 중에서 얼마나 쓰고 있고 또 얼마나 남았는지를 확인해본다.
| 영역 | 전체용량 | 사용량 | 남은양 | Symbol |
| INTERNAL | 0x80002000 | 0x80001F88 | 0x78 | IntermalMemory, TaskQueue, TaskQueuePtr_data, kernel_workspace, TheRootTdesc |
다음은 안의 세부사항이다.
| 세부 영역 | 사이즈 | Symbol |
| internal_section | 0x1A10(6672) | sections.c |
| os20_task_queue | 0x3C0(960) | kernel.c |
| os20_th_data | 0x60(96) | kernel_workspace |
| os20_root_tdesc | 0x18(24) | task.c |
다음은 SDRAM 영역이다. 이 영역은 SDRAM, NONCACHED, EXTERNAL 이 합쳐진 영역이다. SDRAM 영역이 NONCACHED, EXTERNAL 주소까지 쓰고 있다.

위의 외에는 사용하는 영역이 없었다.
이번에는 FLASH에 연결할 때의 경우를 살펴보자!!
