memory access

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

字（word, 4）长度的记忆体取允许不对齐记忆体址，字是以低字节在前的序储在记忆体中。

2.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控制单,此单在完成作的同时,可并行执行多种为优化的微作,如自增量和自减量作,且可实现对循环队列的支持。
