Web9 mrt. 2024 · In hybrid ARM architectures, a so called memory map is implemented, with a different address map configuration of 32-bit, 36-bit, and 40-bit that depends on the requirement of System On a Chip (SoC) address space with extra DRAM. The Memory Map grants interface with SoC design, while having most system control on a high level coding. Web定义： The Device memory type attributes define memory locations where an access to the location can cause side-effects, or where the value returned for a load can vary depending on the number of loads performed. Typically, the Device memory attributes are used for memory-mapped peripherals and similar locations.
