Abstract

PURPOSE:To transfer data at a high speed, by simultaneously loading data on a system bus and a local bus, and transferring it, in a transfer system of data which is sent out to the system bus side from the local bus side. CONSTITUTION:Data is sent from a local bus 5, and when data buffers 11, 12 are filled with data, that is to say, a trigger signal 14 is raised, and the data is sent out to a system bus 4. Also, before the data buffers 11, 2 are filled, that is to say, when data is transferred to the second data buffer 12, a data transfer end signal 7 is made active by receiving a rise of its data transfer start information signal, therefore, the next data is sent out to the local bus 5. During this time, transfer is executed already in the system bus 4.
