To resolve the issue of the execution of efficiency of the system , in addition to a fine structural design of the program , methods such as using a cache memory can both enable the best execution efficiency to your protection management interface program 要解决执行效率的问题,除了程序结构设计要精良外,还可以使用类似高速缓存cache memory的做法,如此将可使保护管理接口程序能有最佳的执行效率。
The design theory of a cache memory is when the work - station users login at a network system and perform programs that had been protected , the protection management interface program will protect data that has usually been referred to by the program by reading with the memories of protection lock and put them into the system s memories . after completing this action , users who login from a work - station can perform programs that have been protected and the software protection management interface program will directly refer to data in the system s memory rather than read the data in the memory of protection lock through many procedures 所谓类似cache memory的做法,其设计原理就是当工作站的用户登入网络系统并且执行已接受保证的程序时,保护程序管理接口会将保护管理接口程序经常需要参考的数据,由保护锁的内存读取后,放入系统的内存中在该动作完成后,再由各工作站登入的使用者执行已接受保护的程序,此时软件保护管理界面程序会直接参考位于系统内存中的数据,而不必再透过多层手续去读取位于保护锁内存中的数据了。
Pipelining and parallel technology , accompanying with fast fifo as cache memory , instead of direct program operation , are adopted in the scheme and increase the transmitting speed dramatically ; fpga ( field programmable gate array ) is applied to realize the complex control logic of the system and makes it integrative , flexible and fast ; 386ex based embedded system , along with vxworks real - time operating system is introduced to substitute the microcontroller based system to simplify the hardware design and enhance the overall performance of ssr , and will make the system more easier to be applied to the projects in the future 该设计方案采用了流水线和并行技术,配以快速fifo缓存的方式取代了直接对flash进行编程的方式,极大地提高了闪存芯片存储数据的速率;采用fpga技术实现系统的主要控制逻辑,集成度高、灵活性好、速度快;采用基于386ex的嵌入式系统及基于vxworks的嵌入式实时操作系统,取代单片机系统及其编程,提高了系统的整体性能,减轻了硬件设计的负担,且使系统研发的延续性好。
