[0038] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] During the R&D phase of a solid-state drive, or after it is sold, firmware upgrades are a must-have feature of the SSD. The stability and cost-effectiveness of firmware upgrades are very important. During firmware upgrades, since the firmware files are large, they are downloaded to the SSD in segments. Figure 1As shown in the figure, the current mainstream solution is to permanently allocate a dedicated DRAM memory space to store the segmented downloaded firmware files. This occupies a large amount of DRAM space (ranging from 1MB to 3MB) and is always occupied, which in turn affects the overall performance of the SSD.

[0040] Based on this, the present invention provides a method for upgrading the firmware based on a solid state drive. Figure 2 The invention concept diagram of the firmware upgrade method based on solid state drive is shown. In the present invention, firmware upgrade is achieved by reusing the write buffer, which can significantly reduce the use of DRAM memory and release DRAM memory for use by other key programs.

[0041] In one embodiment, Figure 3 As shown, a firmware upgrade method based on a solid state drive is provided, the method comprising:

[0042] Step 302: Obtain a firmware upgrade request based on the solid state drive, the request including a firmware download command;

[0043] Step 304: Multiple sub-buffers exist in the write buffer of the solid-state drive for cyclically processing write command requests, and each sub-buffer can process one write command at a time;

[0044] Step 306: When the solid-state drive receives a firmware download command, the configuration parameters of the write buffer are changed so that only one sub-buffer in the write buffer is reserved for processing the write command, and the remaining sub-buffers are freed up for storing new firmware.

[0045] Step 308: When performing a firmware upgrade, the new firmware is downloaded to the write buffer via the firmware download command.

[0046] Step 310: After the firmware upgrade is completed, all sub-buffers are restored to process write commands in a cyclic manner by changing the configuration parameters of the write buffer.

[0047] In this embodiment, a firmware upgrade method based on a solid-state drive is provided to address the drawbacks of mainstream solutions. Since the write buffer is essential in SSD firmware, the permanent occupation of DRAM space can be effectively reduced by reusing the write buffer. The specific implementation process of this method is as follows:

[0048] First, the solid-state drive obtains a firmware upgrade request, which includes a firmware download command. When the firmware is upgraded, the new firmware can be downloaded to the SSD firmware via the firmware download command.

[0049] Next, because the write buffer originally has multiple sub-buffers for processing write commands in a loop, with each sub-buffer capable of handling one write command at a time, when a firmware download command is received, the write buffer configuration parameters are changed to free up multiple sub-buffers to store the new firmware, leaving only one sub-buffer to continue processing write commands.

[0050] Finally, after the firmware upgrade is completed, the configuration parameters of the write buffer are changed to restore the use of all sub-buffers to process write commands in a loop. This does not affect the processing of read and write commands, and the write buffer can be reused to upgrade the firmware.

[0051] In this embodiment, a firmware upgrade request from a solid-state drive (SSD) is obtained, including a firmware download command. When the SSD receives the firmware download command, the write buffer configuration parameters are modified so that only one subbuffer in the write buffer is reserved for processing the write command, leaving the remaining subbuffers free for storing the new firmware. During the firmware upgrade, the new firmware is downloaded to the write buffer using the firmware download command. After the firmware upgrade is complete, the write buffer configuration parameters are modified to restore the use of all subbuffers for cyclically processing write commands. This solution significantly reduces DRAM memory usage by reusing the write buffer to implement firmware upgrades, freeing up DRAM memory for use by other critical programs and thereby improving the overall performance of the SSD.

[0052] In one embodiment, Figure 4 As shown, a firmware upgrade method based on a solid state drive is provided, the method comprising:

[0053] Step 402: There are 8 sub-buffers in the write buffer of the solid-state drive for cyclically processing write command requests, and each sub-buffer can process one write command at a time;

[0054] Step 404: When the solid-state drive receives the firmware download command, the configuration parameters of the write buffer are changed so that only one sub-buffer in the write buffer is reserved for processing the write command, and the remaining seven sub-buffers are freed for storing the new firmware.

[0055] Step 406: When performing a firmware upgrade, the new firmware is downloaded to the write buffer via the firmware download command.

[0056] Step 408: After the firmware upgrade is completed, the configuration parameters of the write buffer are changed to restore the use of all eight sub-buffers to cyclically process write commands.

[0057] refer to Figure 4 As shown, in this embodiment, a method for completely implementing firmware upgrade based on a solid-state drive is provided. The specific execution steps of the method are as follows:

[0058] Step 1: When upgrading the firmware, the new firmware is downloaded to the SSD firmware using the firmware download command.

[0059] Step 2: The write buffer originally has 8 sub-buffers used to process write commands in a loop, where each sub-buffer can process one write command at a time.

[0060] Step 3: When receiving the firmware download command, the configuration parameters of the write buffer are changed to free up 7 sub-buffers to store the new firmware and only retain one sub-buffer to continue processing the write command.

[0061] Step 4: After the firmware upgrade is complete, change the write buffer configuration parameters to restore the use of 8 sub-buffers to process write commands in a loop.

[0062] In this embodiment, the processing of the read and write commands is not affected, and the write buffer can be reused to upgrade the firmware, which can effectively reduce the permanent occupation of the DRAM space.

[0063] It should be understood that although Figure 1-4 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1-4 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
