Abstract: Embodiments relate to managing memory page tables in a processing system. A request to access a desired block of memory is received. The request includes an effective address that includes an effective segment identifier (ESID) and a linear address, the linear address including a most significant portion and a byte index. An entry in a buffer that includes the ESID of the effective address is located. Based on the entry including a radix page table pointer (RPTP), performing: using the RPTP to locate a translation table of a hierarchy of translation tables, using the located translation table to translate the most significant portion of the linear address to obtain an address of a block of memory, and based on the obtained address, performing the requested access to the desired block of memory.
