WebThe MPU memory map is unified. This means instruction accesses and data accesses have the same region settings. If a program accesses a memory location that is prohibited by the MPU, the processor generates a MemManage exception. In an OS environment, the kernel can update the MPU region setting dynamically based on the process to be executed.

WebMemory Mapped IO or MMIO is the process of interacting with hardware devices by by reading from and writing to predefined memory addresses. All interactions with hardware on the Raspberry Pi occur using MMIO. A Peripheral is a hardware device with a specific address in memory that it writes data to and/or reads data from. All peripherals can be … WebA CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.Most CPUs have a hierarchy of …
