| | | | | In our last post we covered how x86 logical address is translated into linear address. In this one we will look at translation from linear to physical. We will use the terms 'virtual address' and 'linear address' interchangeably. A piece of hardware called paging unit is responsible for converting virtual addresses to physical. However, the... | |

| | | | | In the previous post we saw how the memory management unit (MMU) uses page tables to translate virtual addresses into physical ones. We will now consider the various features that such a translation enables in an operating system. In the discussion below, it is important to remember that the granularity of translation is a single... | |

While taking this trip down memory lane I realized that doing a short summary of how large pages are used by the JVM might be an interesting read. | ||
