Description

Technical Field

[0001] This invention relates to the field of storage system technology, and in particular to a method, apparatus, computer device, and storage medium for reducing RF interference in solid-state drives. Background Technology

[0002] Radio frequency interference (RF) refers to the presence of unwanted signals in the radio spectrum used by WiFi networks (most commonly 2.4 GHz and 5 GHz). These unwanted signals are often transmitted by other electronic devices using the same radio waves as the WiFi network. Due to RF interference, WiFi access points and users may be unable to transmit data, reducing their throughput and causing latency and performance degradation issues.

[0003] Currently, many electronic products (most commonly laptops) use both SSDs and Wi-Fi. How to solve the RF interference problem of SSDs on Wi-Fi is a significant system-level issue. Traditional methods for reducing SSD EMI, or in other words, reducing SSD RF interference on Wi-Fi, are achieved through SSC (Spread Spectrum Clocking). The extent to which SSC suppresses EMI radiation depends on the frequency range over which the modulated signal energy varies; the wider the frequency range, the greater the EMI suppression. However, a trade-off is necessary, as a large frequency range can complicate system timing design. Furthermore, SSC introduces additional clock cycle jitter, which can ultimately lead to system errors in some circuit designs. Summary of the Invention

This achieves both performance preservation and reduced SSD RF interference to Wi-Fi. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] Currently, the traditional method for reducing SSD EMI, or in other words, reducing SSD interference with Wi-Fi RF, is SSC (Self-Supported Component Control). The basic process is as follows: Figure 1 As shown.

[0044] Specifically, this is achieved through Spread Spectrum Clocking (SSC). Using SSC effectively reduces EMI (Electromagnetic Susceptibility) generated by the signal, thus reducing RF interference from the SSC to Wi-Fi. Without SSC, the signal energy is highly concentrated and has a large amplitude; with SSC, the signal energy is dispersed within a specific frequency band, and the overall amplitude is significantly reduced, effectively suppressing EMI radiation. This is the basic principle behind using SSC to suppress EMI radiation. The extent to which SSC suppresses EMI radiation depends on the frequency range over which the modulated signal energy varies; a wider frequency range results in greater EMI suppression. However, a trade-off is necessary, as a large frequency range can complicate system timing design. Furthermore, SSC introduces additional clock cycle jitter, which can ultimately lead to system errors in some circuit designs.

[0045] Based on this, the present invention provides a method for reducing RF interference of solid-state drives (SSDs), which aims to efficiently reduce RF interference of SSDs.

[0046] In one embodiment, such as Figure 2 As shown, a method for reducing RF interference in solid-state drives is provided, the method including:

[0047] Step 202: Obtain the implementation request for reducing RF interference from the solid-state drive and determine whether the RF requirements are met;

[0048] Step 204: If the requirements are not met, determine the working frequency of the WIFI and set DeltaF according to the working frequency of the WIFI, where DeltaF is the frequency difference value.

[0049] Step 206: Determine if the SSD system is DRAMLESS;

[0050] Step 208: If yes, increase the operating frequency of the NAND by DeltaF and check again whether RF meets the requirements;

[0051] Step 210: If the requirements are still not met, enable the SSC function to reduce EMI; if the requirements are met, the process ends directly.

[0052] In this embodiment, a method for reducing RF interference from solid-state drives (SSDs) is proposed. This method calculates the frequency fine-tuning range based on the operating bandwidth of Wi-Fi without significantly affecting performance, and adjusts the operating frequency of DRAM or NAND accordingly. This ensures that the harmonics of the operating frequency of DRAM or NAND avoid the Wi-Fi frequency band, thus guaranteeing that performance is not affected while reducing the RF interference of SSDs to Wi-Fi.

[0053] Specifically, the system first retrieves the implementation request for reducing RF interference from the solid-state drive and determines whether the RF requirements are met. If the requirements are not met, the system determines the operating frequency of the Wi-Fi and sets DeltaF accordingly. Here, DeltaF is a variable representing the frequency difference value.

[0054] In one embodiment, if the requirement is not met, the step of determining the operating frequency of the Wi-Fi and setting DeltaF according to the operating frequency of the Wi-Fi, wherein DeltaF is the frequency difference value, further includes:

[0055] Determine whether the Wi-Fi operating frequency is 2.4GHz or 5GHz. If the Wi-Fi operating frequency is 2.4GHz, set DeltaF to 5MHz; if the Wi-Fi operating frequency is 5GHz, set DeltaF to 20MHz. Specifically, the center frequency of each Wi-Fi 2.4GHz channel increases in multiples of 5MHz; the bandwidth of the Wi-Fi 5GHz channel increases in multiples of 20MHz.

[0056] Next, it is determined whether the SSD system is DRAMLESS. If it is a DRAMLESS SSD, the operating frequency of the NAND (NAND flash memory) is increased by DeltaF, and the RF performance is checked again to see if the requirements are met. If the requirements are still not met, the SSC function is enabled to reduce EMI; if the requirements are met, the process ends directly. Obviously, there is a possibility that the SSC function can be omitted in this solution.

[0057] In this embodiment, a request to reduce RF interference from the solid-state drive (SSD) is obtained, and it is determined whether the RF requirements are met. If the requirements are not met, the operating frequency of the Wi-Fi is determined, and DeltaF is set according to the Wi-Fi operating frequency, where DeltaF is the frequency difference value. It is then determined whether the SSD system is DRAM-less. If so, the operating frequency of the NAND is increased by DeltaF, and the RF requirements are determined again. If the requirements are still not met, the SSC function is enabled to reduce EMI. If the requirements are met, the process ends directly. This solution, without significantly affecting performance, calculates the frequency fine-tuning range based on the Wi-Fi operating bandwidth and adjusts the operating frequency of the DRAM or NAND accordingly, ensuring that the harmonics of the DRAM or NAND operating frequency avoid the Wi-Fi frequency band. This achieves both performance preservation and reduced RF interference from the SSD to the Wi-Fi.

[0058] In one embodiment, such as Figure 3 As shown, a method for reducing RF interference in solid-state drives (SSDs) is provided. This method, after determining whether the SSD system is DRAM-less, further includes:

[0059] Step 302: If it is not a DRAMLESS SSD, increase the operating frequency of the DRAM by DeltaF and check again whether the RF meets the requirements.

[0060] Step 304: If the requirements are still not met, increase the operating frequency of the NAND by DeltaF and check again whether the RF meets the requirements. If the requirements are met, the process ends directly.

[0061] Step 306: If the requirements are still not met, enable the SSC function to reduce EMI; if the requirements are met, the process ends directly.

[0062] In this embodiment, reference Figure 4 As shown, a method for reducing SSD RF interference is provided. This process is embedded into a complete process for reducing SSD RF interference to WIFI, forming a complete method and process, thereby achieving an efficient method and process for reducing SSD RF interference.

[0063] 1. Determine if the RF meets the requirements. If it does, proceed to step 11. If it does not, proceed to step 2.

[0064] 2. Determine if the WIFI operates at a 2.4G frequency. If it does, proceed to step 3. If it does not operate at 2.4G (5G WIFI), proceed to step 4.

[0065] 3. Set DeltaF to 5MHz, then proceed to step 5.

[0066] 4. Set DeltaF to 20MHz, then proceed to step 5.

[0067] 5. Determine if the SSD system is DRAMLESS. If yes, proceed to step 6; otherwise, proceed to step 7.

[0068] 6. Increase the operating frequency of NAND by DeltaF, then proceed to step 8.

[0069] 7. Increase the DRAM operating frequency by DeltaF, then proceed to step 9.

[0070] 8. Determine if RF meets the requirements. If not, proceed to step 10. If it does, proceed to step 11.

[0071] 9. Determine if RF meets the requirements. If not, proceed to step 6. If it does, proceed to step 11.

[0072] 10. Enable SSC function to reduce EMI, then proceed to step 11.

[0073] 11. Process complete.

[0074] In this embodiment, the final technical effects achieved include: there is a probability that the SSC function can be omitted; the method does not affect performance; the frequency that needs to be fine-tuned is automatically calculated based on the working frequency of WIFI, and the DRAM or NAND frequency is adaptively fine-tuned so that the harmonics of the working frequency of DRAM or NAND avoid the working frequency band of WIFI.
