Systems and methods to extend rom functionality |
摘要 |
Various embodiments allow for flexible and secure updates of drivers for numerous types of external memory devices by utilizing an address-selection mechanism within a simple and secure ROM code to enable the loading of a dynamic routine from an external source into a dynamic memory. In certain embodiments, the routine enables a simple and trusted framework to access and modify the content of any number of complex memory devices via simple commands without affecting existing security measures. This increases the usable lifetime of secure ROM code, simplifies device validation, and shortens the overall development cycle by extending the functionality of secure ROM code while keeping the ROM code and any programming thereof simple. |
