Control the access source to access the storage space corresponding to each access source in the storage system according to the access request, wherein the corresponding storage space includes at least one exclusive storage unit, and at least one of the exclusive storage units is only connected to a corresponding access source.

[0026] In this embodiment, the corresponding storage space may include one or more exclusive storage units. The exclusive storage unit may be an exclusive storage unit that is electrically connected to only one corresponding access source through wiring.

[0028] In the present application, at least one exclusive storage unit or exclusive configuration unit in the exclusive storage unit in the storage system is electrically connected only to a corresponding access source through wiring in advance in the circuit, so that in the hardware wiring, at least one exclusive storage unit or exclusive configuration unit in the exclusive storage unit does not have wiring to other access sources, thereby effectively reducing the wiring area of ​​the circuit in the storage system on the hardware circuit layout, and effectively reducing the wiring difficulty of the circuit; and by resetting the exclusive storage unit in the storage system, a one-to-one access relationship between the exclusive storage unit and the access source in the storage system is established, thereby avoiding access conflicts caused by the connection of multiple access sources to multiple memories.

[0029] Compared with the prior art, the present application provides an access control method for a storage system, which controls the access source to access the storage space corresponding to each access source in the storage system according to the access request by receiving an access request sent by an access source, wherein the corresponding storage space includes at least one exclusive storage unit, and at least one of the exclusive storage units is only connected to a corresponding access source. In the present application, at least one of the exclusive storage units in the storage system is electrically connected to only a corresponding access source through wiring in the circuit in advance, so that in the hardware wiring, at least one of the exclusive storage units does not have wiring for other access sources, thereby effectively reducing the wiring area of ​​the circuit in the storage system on the hardware circuit layout, and effectively reducing the wiring difficulty of the circuit.

[0030] As an implementation mode, in the embodiment of the present application, the corresponding storage space also includes a shared configuration unit, and multiple access sources are connected to the shared configuration unit.

[0031] In this embodiment, the shared configuration unit may include one or more memories; one access source may be electrically connected to the shared configuration unit, or multiple access sources may be electrically connected to the shared configuration unit.

[0032] For example, the storage space corresponding to access source A also includes a shared configuration unit, which may include memory 1 and memory 2. Access source A may be electrically connected to memory 1 and memory 2, or access source A and access source B may be electrically connected to memory 1 and memory 2.

[0033] As an implementation manner, in an embodiment of the present application, a configuration method of a shared configuration unit includes: A configuration instruction is received, and according to the configuration instruction, a shared configuration unit is configured so that a mapping relationship is established between the shared configuration unit and a plurality of access sources.

[0034] In this embodiment, the shared configuration unit may include one or more configuration memories, and one or more configuration memories in the shared configuration unit may be configured as shared configuration memories according to the configuration instructions, so that a mapping relationship is established between the one or more shared configuration memories and each access source; if the shared configuration unit includes multiple configuration memories, one or more configuration memories may also be configured as exclusive configuration memories of an access source according to the configuration instructions, so that a one-to-one mapping relationship is established between the exclusive configuration memory and the access source, and the remaining configuration memories may be configured as shared configuration memories, so that a mapping relationship is established between the corresponding shared configuration memories and each access source.

[0035] As an implementation mode, in an embodiment of the present application, according to the configuration instruction, the shared configuration unit is configured so that a mapping relationship is established between the shared configuration unit and multiple access sources, including: The configuration instruction includes a shared configuration instruction, which configures the corresponding configuration memory in the shared configuration unit as a shared configuration memory, so that a mapping relationship is established between the corresponding shared configuration memory and each access source.

[0036] It should be noted that since the shared configuration units are electrically connected to each access source, that is, all memories in the shared configuration units are electrically connected to each access source, in actual use, configuration instructions can be set according to actual use requirements. For example, different types or different numbers of memories can be configured in the shared storage unit for different access sources according to different scenario requirements. Assuming that in a scenario with a large data demand or a large storage space demand, access source A needs to mobilize multiple memories in the shared configuration unit to perform a task, configuration instructions can be set to facilitate the subsequent establishment of a mapping relationship between access source A and a plurality of memories in the shared configuration unit according to the configuration instructions, and then the plurality of memories can be accessed or accessed according to the specific access request of access source A. Or data reading or data import; assuming that in a scenario with small data demand or small storage space demand, access source B only needs to mobilize a small number of memories in the shared configuration unit to perform tasks, then the configuration instruction can be set to facilitate the subsequent establishment of a mapping relationship between access source B and a small number of memories in the shared configuration unit according to the configuration instruction, and then the large number of memories can be accessed or data read or data imported according to the specific access request of access source B. That is, by setting the type of configuration instruction, it is convenient to establish mapping relationships between different access sources and different types or different numbers of memories respectively; at the same time, different access sources can also be directly connected to different types or different numbers of memories by wiring.

[0037] In this embodiment, if the received configuration instruction includes a shared configuration instruction, one or more configuration memories in the shared configuration unit are configured as shared configuration memories, so that a mapping relationship is established between the one or more shared configuration memories and each access source.

[0038] For example, the shared configuration unit includes memory 1 and memory 2. If the received configuration instruction includes a shared configuration instruction, memory 1 and memory 2 in the shared configuration unit are configured as shared configuration memories so that a mapping relationship is established between memory 1 and memory 2 and each access source.

[0039] In this embodiment, if the received configuration instructions include some shared configuration instructions, one or more configuration memories are configured as exclusive configuration memories corresponding to one of the access sources, so that a one-to-one mapping relationship is established between the exclusive configuration memory and the access source, and the remaining configuration memories are configured as shared configuration memories, so that a mapping relationship is established between the corresponding shared configuration memories and each access source.

[0040] For example, the shared configuration unit includes memory 1 and memory 2. If the received configuration instruction includes some shared configuration instructions, memory 1 is configured as an exclusive configuration memory corresponding to access source A, so that the exclusive configuration memory, i.e., memory 1, establishes a one-to-one mapping relationship with access source A, and memory 2 is configured as a shared configuration memory, so that memory 2 establishes a mapping relationship with both access source A and access source B.

[0041] As an implementation mode, in an embodiment of the present application, if an exclusive storage unit is connected to multiple access sources, the exclusive storage unit is an exclusive shared configuration unit, and the configuration method of the exclusive shared configuration unit includes: A configuration instruction is received, and according to the configuration instruction, a shared configuration unit is configured so that a mapping relationship is established between the shared configuration unit and only one access source.

[0042] In this embodiment, if an exclusive storage unit in the storage space corresponding to an access source is electrically connected to multiple access sources, it means that the exclusive storage unit is an exclusive shared configuration unit, and the configuration method of the exclusive shared configuration unit includes: receiving a configuration instruction, and configuring the shared configuration unit according to the received configuration instruction, so that the shared configuration unit is configured as an exclusive shared configuration unit, so that the shared configuration unit only establishes a mapping relationship with one access source.

[0043] For example, if the exclusive storage unit in the storage space corresponding to access source A is electrically connected to access source A and access source B, it means that the exclusive storage unit is an exclusive shared configuration unit, and the configuration method of the exclusive shared configuration unit includes: receiving a configuration instruction, and configuring the shared configuration unit according to the received configuration instruction, so that the shared configuration unit is configured as an exclusive shared configuration unit, so that the shared configuration unit only establishes a mapping relationship with access source A.

[0044] As an implementation mode, in an embodiment of the present application, according to the configuration instruction, the shared configuration unit is configured so that the shared configuration unit only establishes a mapping relationship with one access source, including: The configuration instruction includes an exclusive configuration instruction, which configures the corresponding configuration memory in the shared configuration unit as an exclusive configuration memory, so that a one-to-one mapping relationship is established between the exclusive configuration memory and the access source.

[0045] In this embodiment, the shared configuration unit may include one or more configuration memories. According to the exclusive configuration instruction, one or more configuration memories in the shared configuration unit are configured as exclusive configuration memories corresponding to one of the access sources, so that a one-to-one mapping relationship is established between the exclusive configuration memory and the access source.

[0046] For example, the shared configuration unit includes memory 1 and memory 2. According to the exclusive configuration instruction, memory 1 and memory 2 in the shared configuration unit are configured as exclusive configuration memories corresponding to access source A, so that memory 1 and memory 2 establish a one-to-one mapping relationship with access source A.

[0047] As an implementation manner, in the embodiment of the present application, step S2 includes: S21, obtaining a physical address of a corresponding storage space according to an access request and an access relationship between an exclusive storage unit, a shared configuration unit and an access source, wherein the access relationship includes a connection relationship and / or a mapping relationship between an exclusive storage unit and an access source, and a connection relationship and / or a mapping relationship between a shared configuration unit and an access source; In this embodiment, the access relationship between the exclusive storage unit, the shared configuration unit and the access source may include an electrical connection relationship established between the exclusive storage unit and the access source through wiring and / or a mapping relationship established between the exclusive storage unit and the access source, an electrical connection relationship established between the shared configuration unit and the access source through wiring and / or a mapping relationship established between the shared configuration unit and the access source through configuration instructions, that is, the aforementioned access relationship may include an access relationship jointly established by the electrical connection relationship between the exclusive storage unit and the access source and the electrical connection relationship between the shared configuration unit and the access source; it may also include an access relationship jointly established by the electrical connection relationship between the exclusive storage unit and the access source and the mapping relationship established between the shared configuration unit and the access source through configuration instructions; it may also include an exclusive storage unit. The access relationship may include an access relationship jointly established by a mapping relationship established by a configuration instruction method and an electrical connection relationship between a shared configuration unit and an access source, which are first electrically connected to each other and then established through configuration instructions, and an access relationship jointly established by a mapping relationship established by a configuration instruction method and a shared configuration unit and an access source, respectively; the access relationship may also include an access relationship jointly established by an electrical connection relationship established by wiring between one exclusive storage unit and an access source and a mapping relationship established by wiring between another exclusive storage unit and an access source, an electrical connection relationship established by wiring between a shared configuration unit and an access source and a mapping relationship established by a configuration instruction method and a shared configuration unit and an access source.

[0048] Furthermore, by parsing the access request of the access source, the request address of the access source can be obtained, and then based on the request address and the access relationship between the exclusive storage unit, the shared configuration unit and the access source, the physical address of the storage space corresponding to the access source can be obtained.

[0049] For example, the storage space corresponding to the access source A includes an exclusive storage unit and a shared configuration unit, the exclusive storage unit includes memory 0, and the shared configuration unit includes memory 1 and memory 2. It can be that memory 0 is electrically connected to the access source A, and memory 1 and memory 2 are electrically connected to the access source A, so that an access relationship is established between memory 0, memory 1 and memory 2 and the access source A; it can also be that memory 0 is electrically connected to the access source A and a mapping relationship is established through configuration instructions, and memory 1 and memory 2 are electrically connected to the access source A, so that an access relationship is established between memory 0, memory 1 and memory 2 and the access source A; it can also be that memory 0 is electrically connected to the access source A, and memory 1 and memory 2 are electrically connected to the access source A and a mapping relationship is established through configuration instructions, so that an access relationship is established between memory 0, memory 1 and memory 2 and the access source A; it can also be that memory 0 is electrically connected to the access source A and a mapping relationship is established through configuration instructions, and memory 1 and memory 2 are electrically connected to the access source A and a mapping relationship is established through configuration instructions, so that an access relationship is established between memory 0, memory 1 and memory 2 and the access source A; The access request of access source A can be parsed to obtain the request address of access source A, and then the physical address of the storage space including memory 0, memory 1 and memory 2 corresponding to access source A can be obtained according to the request address and the access relationship between memory 0, memory 1 and memory 2 and access source A; like Figure 2 As shown, when there are multiple access sources, configuration instructions can be set according to actual usage requirements. For example, different types or different numbers of memories can be configured in the shared storage unit for different access sources according to different scenario requirements. For example, access source A needs to mobilize multiple memories in the shared configuration unit to perform tasks, and access source B only needs to mobilize a few memories in the shared configuration unit to perform tasks. Therefore, by setting wiring and configuration instructions, corresponding storage spaces are set for subsequent access sources A and B. The storage space corresponding to access source A includes a first exclusive storage unit and a first shared configuration unit, and the storage space corresponding to access source B includes a second exclusive storage unit and a second shared configuration unit. The storage system includes memory 0, memory 1, memory 2, memory 3, and memory 4. The first exclusive storage unit includes memory 0, and the second exclusive area includes memory 4. For memory 1, memory 2, and memory 3 in the shared configuration unit, memory 1 and memory 2 in the shared configuration unit can establish an access relationship with access source A by wiring or wiring first and then by configuration instructions, and memory 3 in the shared configuration unit can establish an access relationship with access source B by wiring or wiring first and then by configuration instructions.

[0050] In the present application, the effect of reducing wiring is achieved by setting an exclusive storage unit in the storage system, and by splitting the storage system into storage spaces corresponding to each access source, access conflicts caused by connecting multiple access sources to multiple memories are avoided.

[0051] S22. According to the physical address of the corresponding storage space, control the access source to access the corresponding storage space.

[0052] In this embodiment, the access source is controlled to access the corresponding storage space according to the physical address of the storage space corresponding to the access source, so that the access source can read data or write data to the corresponding storage space.

[0054] The present application also provides a storage system, which includes at least one exclusive storage unit, and at least one of the exclusive storage units is connected to only one corresponding access source.
