A secure microcontroller system comprising an integrated cache sub-system, crypto-engine, buffer sub-system and external memory is described according to various embodiments of the invention. The secure microcontroller incorporates block encryption methods to ensure that content communicated between the integrated microcontroller and external memory is protected and real-time performance of the system is maintained. Additionally, the microcontroller system provides a user-configurable memory write policy in which memory write protocols may be selected to balance data coherency and system performance. |
