PURPOSE:To transfer data at a high speed and in a large capacity by using pipelines to perform three basic actions, i.e., the arbitration, the transfer of data and the acknowledge which are involved in a single data transfer action. CONSTITUTION:A peripheral device which transfers data carries out arbitration to acquire the bus using right. In the next bus clock cycle the peripheral device acquired the bus using right sends data via a data line 2. Then the arbitration is carried out on an arbitration line 1 for the next transfer of data. In a bus clock cycle following the next cycle a peripheral device set at the reception side and received data sends back an acknowledge via an acknowledge line 3. Then the next transfer of data is carried out via the line 2 and the arbitration is carried out on the line 1 for the next transfer of data. |
