byte aligned vs word aligned

Word alignment
If the ints are aligned on word boundaries there must be 3 bytes between the chars and the ints This means that the size of the struct is 16 bytes if |
What is word alignment in memory?
For the 32-bit ARM CPU, word alignment means that memory is grouped into collections of 4-byte words, and the transfers occur on words.
Thus the memory at addresses 0x0, 0x4, 0x8, 0xc, 0x10, etc., can be transferred from memory to a register.29 jui. 2023For instance, if the address of a data is 12FEECh (1244908 in decimal), then it is 4-byte alignment because the address can be evenly divisible by 4. (You can divide it by 2 or 1, but 4 is the highest number that is divisible evenly.) CPU does not read from or write to memory one byte at a time.
What does word aligned mean?
Word-aligned means the address is stored at an address that's divisible by 4.
If the bytes in the data are not divisible by 4; this results in zeros being used to “pad” the address at the end ( 00 for a word(32 bits)).
What does byte aligned mean?
A memory address a is said to be n-byte aligned when a is a multiple of n (where n is a power of 2).
In this context, a byte is the smallest unit of memory access, i.e. each memory address specifies a different byte.
