<p>PURPOSE: To prevent data from stagnating by suppressing a bottleneck of an external bus, etc. CONSTITUTION: An external receiving driver 11 receives data from the external bus 1, performs signal processing, and issues trigger signals S11-1 and S11-2 at the same time to send the processed data to the external bus 1. With the trigger signal S11-2, an external transmitting driver 14 sends the data to the external bus 1. An inter-CPU output driver 12 receives data with the trigger signal S11-1, performs signal processing, and performs transmission. An inter- CPU input driver 13 receives data and sends the data to the external transmitting driver 24. A CPU input driver 21 receives data, performs signal processing, and sends the processed data to a signal processing application program 23. The inter-CPU input driver 21 issues a trigger S21 and the inter-CPU output driver 23 sends data to the inter-CPU driver 11 with the trigger S21.</p> |
