Embodiment Construction

[0036] The technical solutions in the embodiments of the present application are clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0037] Figure 2A is a schematic diagram of unified address mapping according to an embodiment of the present application.

[0038] For the sake of clarity, the storage space in which the program accesses the memory is called the memory address space, and the storage space in which the program accesses the external memory is called the external memory address space.

[0039] see Figure 2A , according to the embodiment of the present application, the memory address space and the e...

Abstract

The invention provides a unified address translation and a unified address space. The address conversion method provided by the invention comprises the following steps: acquiring an address and a storage device type of a program access storage device; generating an address in a unified address space according to the address of the storage device and the type of the storage device; converting the address in the unified storage space into an address which can be received by the storage equipment; and accessing the storage device using the address receivable by the storage device.

Description

technical field [0001] The present application relates to an information processing device, and in particular, relates to providing unified address translation for various storage devices of the information processing device, and providing a unified address space for various storage devices. Background technique [0002] figure 1 A block diagram of an information processing device is shown. An information processing device includes a CPU and a memory (Memory, also referred to as memory). The information processing device is also coupled to one or more of external storage (Storage) devices such as SSD (Solid State Drive), NVDIMM (Non-Volatile Memory Module), mechanical hard disk (HDD), and KV storage device. [0003] For the sake of clarity, in this application, storage devices are used to collectively indicate internal memory devices and external storage devices. Applications running on the CPU use various forms of addressing to use storage devices. For example, memory a...
