Instruction conversion system and instruction conversion method

An instruction conversion method is used in an instruction conversion system comprising a first transmit-receive interface and a second transmit-receive interface, and the instruction conversion method comprises the following steps: receiving at least one instruction transmitted by a first device through the first transmit-receive interface; determining, by the instruction conversion system, a first order rule representing whether the first device needs to process the instruction according to the order and a second order rule representing whether the second device needs to process the instruction according to the order; transmitting the instruction to the second device through the second transmit-receive interface; according to the second order rule, the second device processes the instruction and transmits the reply to the second transceiving interface; and transmitting the reply to the first device through the first transceiving interface according to the first order rule. 一种指令转换方法，使用在包含一第一传收接口以及一第二传收接口的一指令
