Alignment refers to a piece of data's location in memory. A variable is naturally aligned if it exists at a memory address that is a multiple of its size. For example, a

Addresses of variables declared globally (within a CUDA file):. int my_array { 1, 2, 3, The obsolete function memalign() allocates size bytes and returns a pointer to the allocated memory.

Use ALIGN 4 to ensure four-byte alignment of an address within Thumb code. Use ALIGN to take advantage of caches on some ARM processors. For example, the ARM940T has a cache with 16-byte lines.

If the number of transmitted bytes is at least one but less than or equal to the program page size (256 or 512 bytes), then the non-0xFF data is programmed from the buffer to the chosen flash page address starting at the rising edge of CS#.

0 is allowed. "X bytes aligned" means that the base address of your data must be a multiple of X. It can be used for using some special hardware like a DMA in some special hardware, for a faster access by the cpu, etc It is the case of the Cell Processor where data must be 16 bytes aligned in order to be copied to/from the co-processor.

Revising the Memory Allocator's Address Alignment. This memory allocator code is based on CS:APP and was originally written for a 32-bit address CPU. The intention when this code was written was to align the addresses of all allocated blocks of memory on an 8-byte address boundary.

Four bytes of data are loaded from the resulting address. The loaded data is rotated right by one, two or three bytes according to bits [1:0] of the address. For a little-endian memory system, this causes the addressed byte to occupy the least significant byte of the register.
An access to an object of size s bytes at byte address A is aligned if A mod s = 0. Misalignment causes hardware complications, since the memory is typically aligned on a word boundary. A misaligned memory access will, therefore, take multiple aligned memory references. Alignment starts when you have more than one byte, two bytes, if aligned means the lsbit of the address is a zero, unaligned means it is a one.
