How use SRAM program Arduino IDE on Due 32bit lower bit variables.

Example i use 4time uint8_t. IDE used 4 times 32bit or all variables add to one 32 bit adress (4*8=32). And if use one 32 memory adress then with mask &255 first uint8_t, & (65535-255)>>8 etc for second uint8_t etc with SW or on HW virtual adress if exists examlne adress A 32bit, adress B1 on low A and B2 adress on high A (int16_t, uint16_t) , C1 adress on low B1, C2 on high B1, C3 on low B2 and C3 on high B2 (uint8_t, int8_t).... If exists virtual adress on lower size variables...
???

Post your example code, then form your question around the code presented.

uint8_t a=255;
uint8_t b=255;
uint8_t c=255;
uint8_t d=255;

How much used memory real.

ce4aser:

uint8_t a=255;

uint8_t b=255;
uint8_t c=255;
uint8_t d=255;




How much used memory real.

Those are 1 byte each.

And i'm not sure but I think there is no virtual memory here.
