Abstract:
1. A read/write method for a data buffer system between a first interface device and a second interface device, comprising: providing a first interface controller having a first interface and a first common interface, wherein the first interface controller communicates with the first interface device via the first interface, and communicates with a data buffer device via the first common interface; providing a second interface controller having a second interface and a second common interface, wherein the second interface controller communicates with the second interface device via the second interface, and communicates with the data buffer device via the second common interface; providing the data buffer device having a read unit and a write unit, wherein the read unit comprises a first read buffer, a second read buffer and a read controller, and the write unit comprises a first write buffer, a second write buffer and a write controller; and applying a write operation when the first interface device transmits data to the second interface device via the data buffer device, the write operation comprising: applying a read operation when the first interface device reads data from the second interface device via the data buffer device, the read operation comprising:
