![]() First of all, it gives the CPU an opportunity to cache accesses, greatly speeding up the efficiency of accessing often used values. ![]() ![]() The games are given access to virtual memory instead of real memory for several reasons. This can be done in two ways, with Block Address Translations (BATs) for huge portions of memory or the page tables for small fine-grained mappings. Rather than directly accessing available RAM, games interface with virtual memory which is then translated to physical memory by the MMU. The Memory Management Unit, or MMU, is responsible for quickly giving games access to data and code.
