AN1607: How to Configure Memory Protection Unit (MPU)

WebThe Memory Protection Unit (MPU) manages the CPU's access to the memory and ensures a task does not accidentally corrupt the memory or the resources used by other active tasks. The MPU is usually controlled by a RTOS. If a program accesses a memory location that is prohibited by the MPU, the RTOS can detect it and act. WebA memory protection unit is included to allow secured execution of applications on GAP8. All 9 cores share the same extended RISC-V instruction set architecture. The I (integer), C (compressed instruction), M (Multiplication and division) extensions and a portion of the supervisor ISA subsets are supported. reicod fiberglass https://instrumentalsafety.com
