Word sized memory access is allowed to unaligned memory addresses.Words are stored in the little-endian order.

字组（word, 4位组）长度的记忆体存不对齐记忆体位址，字组是以低位字节在前的顺序存在记忆体中。

When the memory is accessed,the unit can execute some micro-operation which is optimized for memory access such as autoincrement and autodecrement in parallel and also support circular queue.

提出一种新型结构的内存控制,在完成访存操作的同时,可并行执行多种为访存优化的微操作,如自增量和自减量操作,且可实现对循环队列的支持。
