In the ARMv8 architecture, the standard implementation uses a 48-bit virtual address space for addressing. This allows for a significantly larger number of addressable locations compared to smaller bit-length addressing schemes. The 48-bit addressing capability is particularly advantageous as it enables efficient memory management and a vast range of possible memory addresses, accommodating the needs of modern applications that require large amounts of memory. While some other architectures or older versions may utilize 32-bit or 64-bit addressing, in the case of ARMv8, 48 bits are specified as the amount used for virtual address space. This is a design choice that aligns with typical application demands and helps facilitate features such as SAMPLEadvanced virtual memory management, including paging and other methods of translating logical addresses to physical memory locations.
