Technical Field

Background
With the increasing Processing speed of the existing host CPU (Central Processing Unit), a large number of command queues are supported by the newly added bus protocol, and whether the host device can operate to an optimized state depends on the optimized management mode of the host device for the command queues.
The existing implementation scheme for optimizing and managing the command queue generally directly converts the command information in the command queue into information required by the back end, and once the back end is free, the new command is directly sent to the back end for execution. The efficiency of the back end can be improved by doing so, but the performance of the host device is not necessarily improved, if a task is decomposed into 2 back end write commands, represented by W0, W1 and 2 back end read commands, represented by R2, R3, and the back end processes the W0 write command, it is found that the recovery flow needs to be started inside, if the W1 write command is processed subsequently or directly, the recovery load is increased, and at this time, the subsequent processing of the R2 read command may be exactly the data required by the recovery process to read the command, and such efficiency is optimized, once the recovery flow is not started inside the system, the W1 needs to be processed continuously, so that the command is sent out of order without the back end having free space, and the decision needs to be made according to the state of the current system.

the host equipment sends command queue buffer information;
the controller receives command queue buffer information sent by the host equipment;
the controller performs logical address mapping conversion on the received command queue buffer information to obtain a mapping table associated with the command queue buffer information;
the controller calculates the required storage resource according to the command queue buffer information recorded by the mapping table obtained by conversion;
the controller detects whether the current storage state of the host equipment meets the calculated required storage resource or not, and controls the host equipment to orderly process each single command in the command queue buffer information associated with the mapping table when detecting that the current storage state of the host equipment meets the calculated required storage resource;
the controller detects whether the current storage state of the host device meets the calculated required storage resource, when the current storage state of the host device is detected to not meet the calculated required storage resource, the controller traverses whether the same command in the command queue associated with the mapping table exists in the storage resources cached by the host device, deletes the same command from the mapping table when the same command in the command queue associated with the mapping table exists in the storage resources cached by the host device, and recovers the storage resources cached by the host device and not associated with the deleted command.

the controller decomposes the command queue buffer information according to the converted command queue buffer information recorded by the mapping table to obtain each single command, and calculates the storage resource required by each single command according to each single command obtained by decomposition.
3. The method as claimed in claim 1, wherein the controller detects whether the current storage status of the host device satisfies the calculated required storage resource, and controls the host device to process each single command in the command queue buffer information associated with the mapping table when detecting that the current storage status of the host device satisfies the calculated required storage resource, further comprising:
the controller detects whether the current storage state of the host device meets the calculated required storage resource, and when the current storage state of the host device is detected not to meet the calculated required storage resource, the controller recycles the storage resource cached by the host device until the current storage state of the host device can meet the calculated required storage resource.
4. The method as claimed in claim 1, wherein after the controller detects whether the current storage status of the host device satisfies the calculated required storage resource and controls the host device to process each single command in the command queue buffer information associated with the mapping table in order when the current storage status of the host device is detected to satisfy the calculated required storage resource, the method further comprises:
and the host equipment processes each single command in the command queue buffer information associated with the mapping table in order according to the control of the controller.
5. A system for implementing command queue optimization management is characterized by comprising:
a host device and a controller;
the host equipment is used for sending command queue buffer information;
the controller is used for receiving the command queue buffer information sent by the host equipment, performing logical address mapping conversion on the received command queue buffer information to obtain a mapping table associated with the command queue buffer information, calculating required storage resources according to the command queue buffer information recorded by the mapping table obtained by conversion, detecting whether the current storage state of the host equipment meets the calculated required storage resources, and controlling the host equipment to process each single command in the command queue buffer information associated with the mapping table in order when detecting that the current storage state of the host equipment meets the calculated required storage resources;
the controller is specifically configured to:
detecting whether the current storage state of the host device meets the calculated required storage resource, when detecting that the current storage state of the host device does not meet the calculated required storage resource, traversing whether the same command in the command queue associated with the mapping table exists in the storage resources already cached by the host device, deleting the same command from the mapping table when traversing that the same command in the command queue associated with the mapping table exists in the storage resources already cached by the host device, and recovering the storage resources which are cached by the host device and are not associated with the deleted command.
6. The system for implementing command queue optimization management of claim 5, wherein the controller is specifically configured to:
and decomposing the command queue buffer information according to the converted command queue buffer information recorded by the mapping table to obtain each single command, and calculating the storage resource required by each single command according to each single command obtained by decomposition.
7. The system of claim 5, wherein the controller is specifically configured to:
detecting whether the current storage state of the host equipment meets the calculated required storage resource, and when detecting that the current storage state of the host equipment does not meet the calculated required storage resource, recycling the cached storage resource of the host equipment until the current storage state of the host equipment can meet the calculated required storage resource.
8. The system for implementing command queue optimization management of claim 5, further comprising:
a processing module;
and the processing module is arranged in the host equipment and used for orderly processing each single command in the command queue buffer information associated with the mapping table according to the control of the controller.
