内存拷贝方法及装置
摘要：
本发明提供一种内存拷贝方法及装置，读取包括16字节取指令以及16字节存指令的内存拷贝可执行文件，16字节取指令包括源地址和两个寄存器标识，16字节存指令包括目的地址和两个寄存器标识，执行内存拷贝时，通过16字节的取指令读取源地址对应的内存中的待拷贝数据存储到寄存器中，并通过16字节的存指令将寄存器中的待拷贝数据存储在目的地址对应的内存中，由于16字节的取指令和16字节的存指令操作的数据介于0字节至16字节之间，因此可以突破现有技术中只能进行8字节的内存拷贝的限制，提升了内存拷贝速度。
摘要（英）：

The invention provides a memory copy method and device. The memory copy method comprises the following steps: reading a memory copy executable file that includes a 16 byte read instruction and a 16 byte storage instruction, wherein the 16 byte read instruction includes a source address and two register identifier, and the 16 byte storage instruction includes a destination address and two registeridentifier; and executing the memory copy: reading the data to be copied in the memory corresponding to the source address through the 16 byte read instruction and storing in the register, and storingthe data to be copied in the register in the memory corresponding to the destination address through the 16 byte storage instruction. Because the data operated by the 16 byte read instruction and the16 byte storage instruction is between 0 byte to 16 bytes, therefore, the limitation of 8 byte memory copy in the prior art can be broken, and the memory copy speed is improved.
