STM32F7的SRAM不够用了

很好SRAM2到底存了哪些内容，不都是保存变量的吗？这是我所有的变量，
const int a0=21000;
const int a1=22000;
const int a2=23000;
const int a3=26000;
const int a4=27000;
const int a5=28000;
const int a6=20000;
const int a7=30000;
const int a8=100;
const int n=30;
int key=0,count=0;//°′¼ü¼ì2a,LED·′×aê¼Æêy

double c1[BUFFERSIZE];
double c2[BUFFERSIZE];
double y[BUFFERSIZE*2];
double c3[BUFFERSIZE];
double c4[BUFFERSIZE*4];
float x[BUFFERSIZE*8];
float c5[BUFFERSIZE*8];
int c6[6][12];
int c7[100];
struct sta state[64][N];

W w;
C c;
D d;

M m;
F fb;
FR fr;
CM cm;
CB cb;
int i=0,j=-1;
u8 timeout=0;

typedef struct{
u16 b[BUFFERSIZE];
u16 b[BUFFERSIZE];
u16 bg;
u16 gb;
int i1;
int i2;
}M;

typedef struct{
float f1[BUFFERSIZE*2]; //FFTêäèëêy×é
float f2[BUFFERSIZE]; //FFTêä3öêy×é
int f;
}F;

typedef struct{
float f[BUFFERSIZE];
float y[BUFFERSIZE];
int l;
} FR;

typedef struct{
int w1;
int w2;
int i;
}W;

typedef struct{
int w;
int c1;
int c2;
int c3;
int c4;
int c5;
int i;
int c;
}C;

typedef struct{
int d;
int w;
int i;
int d;
int i;
int is;
u16 y[BUFFERSIZE*5];
}D;

typedef struct{
float f1[BUFFERSIZE*8]; //FFTêäèëêy×é
float f2[BUFFERSIZE*4]; //FFTêä3öêy×é
int f;
}CB;
typedef struct{
int d[100];
int w;
int d;
int da;
unsigned int r[100];
}CM;

内存占用情况，为什么战役这么多！
