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

字（word, 4位）度记忆体存取允许不对齐记忆体位址，字是以低位字节在前顺序存在记忆体中。

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.

提出一种新型结构内存控制单,此单在完成访存操时,可并行执行多种为访存优化微操,如自增量和自减量操,且可实现对循环队列支持。
