WebByte invariance means that the address of a byte in memory is the same irrespective of whether that byte is being accessed in a big endian or little endian manner. Byte, halfword, and word accesses access the same one, two or four bytes in memory for both big and little endian configuration. Double word and multiple word accesses in the ARM ... WebIn byte-invariant big-endian format, the processor stores the most significant byte (msbyte) of a word at the lowest-numbered byte, and the least significant byte (lsbyte) at the highest-numbered byte.

WebJun 3, 2014 · Word invariant meaning word reads give the same answer. A byte read of address zero in little endian mode of the same address would be 0x78 and big endian byte read (ldrb) would be 0x12. So you have to go beyond just saying is it big or little endian but what instruction is being used.
