Abstract: The read modify write (RMW) is executed not occupying system bus for synchronizing the processors of multi process system. The method includes the steps: (A) checking RMW transmission type in a data transmission type generator and a data transmission bus requester (3); (B) discriminating the write or read operation of RMW; (C) executing interlock read operation and receiving AACK signal at RMW read operation; otherwise (D) executing interlock write operation, and checking the locking state using a locking transmission type processor and data transmission bus interfacer (5); (E) sending lock busy signal and OK signal to the bus requester when the bus is locked by the interlock read; and (F) when the bus is locked by the interlock write, sending OK signal, releasing the lock, writing data and sending error signal at the same time.

Abstract translation: 执行读修改写（RMW）不占用用于同步多进程系统的处理器的系统总线。 该方法包括以下步骤：（A）检查数据传输类型发生器和数据传输总线请求器（3）中的RMW传输类型; （B）识别RMW的写入或读取操作; （C）执行联锁读操作，并以RMW读操作接收AACK信号; 否则（D）执行联锁写入操作，并使用锁定传输类型处理器和数据传输总线接口（5）检查锁定状态; （E）当总线被互锁读取锁定时，向总线请求者发送锁定忙信号和OK信号; 和（F）当总线通过互锁写入锁定时，发送OK信号，释放锁定，同时写入数据和发送错误信号。
