Navigation System with the V25 (CPU) and the IDP (Intelligent Display Controller)

AS THE GREAT PROGRESS in electronics technology is achievd, electronization in automotive systems is quickly advancing to satisfy the demands in various applications

These applications are;

1. (1)
   Engine control system designed to deliver the engine's full capacity, while clearing every industrial standards.
2. (2)
   Anti-skidding control system together with safety-system designed to provide the maximum safety for drivers.
3. (3)
   Auto-cruise control system, transmission control system, and navigation system designed for easy driving.
4. (4)
   Auto-air condition control system designed for comfortable driving.

Electronization, in which microprocessors are, involved, gives a limitless number of applications, including those mentioned above.

In this paper is a description on how to design a navigation system in general, plus some detailed discussion on one such system with the V25(µPD70322/320) as the CPU and the IDP (µPD72022) as a controller for the man-machine interface.
