| Abstract: |
| The development steps of microcomputer protection are briefly introduced. The new protection concept improves the protection performance, but it also raises higher recuirements in hardware. The basic structure of microcomputer protection and its development tendency are discussed according to its features of different types and functions, combined with the used processor, data acquisition system,date communication mode and their influences on device performance. The independence of protection function should be emphasized and the universal HW should be developed for realizing open structure and interconnection. |
