Description
Technical field
The present invention relates to computer realm, more particularly to a kind of anonymous page initial method of internal memory, apparatus and system.
Background technology
In computer systems, internal memory typically by DRAM, (visit by Dynamic Random Access Memory, dynamic random
Ask memory) constitute.Because DRAM integrated levels are low, finite capacity.In addition, DRAM belongs to volatile memory device, in order to ensure
Data are not lost, it is necessary to which continuous refresh operation, causes DRAM high energy consumptions.Memory system energy consumption accounts for computer system total energy consumption
Large percentage, energy consumption problem also increasingly becomes the bottleneck of restriction memory system development.Compared with DRAM, new NVM (Non-
Volatile Memory) energy consumption is lower, and because integrated level is high, bigger capacity can be accomplished.As application is held to internal memory
The requirement of amount is increasing, and non-volatile demand is increased, and has only been difficult to meet the need applied by the DRAM internal memories constituted
Ask, NVM is constituted as internal memory or DRAM with NVM and mixes internal memory, by the developing direction as following memory system.
The principle of NVM data storages is, by memory cell add different size, the voltage of different directions or magnetic field etc. come
Change the resistance of memory cell, the data that storage is judged according to the difference of resistive memory cell size are 0 or 1.Such as PCM
(Phase Change Memory, phase transition storage), by adding different size of voltage to change memory cell to memory cell
Resistance；Unipolarity RRAM (Resistive Random Access Memory, resistive formula memory), by memory cell
Plus different size of voltage changes the resistance of memory cell；Bipolarity RRAM, by adding different directions, difference to memory cell
The voltage of size changes the resistance of memory cell；MRAM (Magnetoresistive Random Access Memory, magnetic
Resistive memory), change the resistance of memory cell by adding the magnetic field of different directions to memory cell.It is this single according to storage
First resistance sizes judge 0 and 1 memory device, and it is different with the energy consumption for writing 1 (SET operation) to write 0 (RESET operation).
The memory management module of operating system uses dynamic memory distribution technology, when the page that process is accessed is not in internal memory,
Page fault can be caused, page fault processing routine carries out actual Physical Page distribution.Wherein, page is the interior of unit
Deposit, page includes anonymous page and non-anonymous page.
In the prior art, operating system memory management module is when handling page fault, if this page is quilt for the first time
Process accesses and is anonymous page, then page fault processing routine calls do_anonymous_page () function to obtain one newly
The anonymous page of physics, and call clear_page () function that anonymous all positions of page are initialized as into 0.
All positions of anonymous page are directly initialized as 0, do not account for new NVM and write 0 by operating system in the anonymous page of distribution
Energy consumption difference in size with writing 1, so as to cause energy waste.
The content of the invention
The embodiment of the present invention proposes a kind of anonymous page apparatus for initializing of internal memory for saving energy consumption, method, system, passes through identification
The title and physical address of different internal memories, judge that internal memory writes 0 and writes 1 energy consumption difference, carry out different initialization operations, reduce
The wasting of resources.
