Unaligned and Mixed-endian Data Access 何解？

happybai

最近在看arm1176jzfs_r0p7_trm，中第四章节Unaligned and Mixed-endian Data Access Support，有这样一段描述The processor executes the ARM architecture v6 instructions that support mixed-endian
access in hardware, and assist unaligned data accesses.请问mixed-endian access和unaligned data 是什么意思？ 多谢！

mixed-endian: 支持big-endian and little-endian
unaligned: 非对齐模式，一般处理器访问memory有word, half-word对齐要求，V6对此可以无要求。
