Embedded System (Misc (Register flags (Carry flag (C) (Is set when…

- - - - Is set when sum/subtraction exceeds size of register
    - - Is set when a - b < 0
    - - Is set when
        positive + positive = negative OR
        negative + negative = positive
- - - - Text segment
        
        instructions
        
        literals
        
        2 same literals => gcc compiler will store 1 value to FLASH
        
        interrupt vector table
    - - Data segment
        
        global and static initialized data
      - Bss segment
        
        global and static uninitialized or equal-0 data
        
        Pros
        
        no need to store literals in Flash
        
        allocation at run time
        
        fast load = no need to init value

        local variable
        
        [Info] Stack allocation is faster than heap allocation:
        Just move stack pointer while heap allocated by algorithm
