Description

Technical Field

[0001] This invention relates to the field of embedded system applications, and more specifically, to an amplitude adaptive method, apparatus, medium, and system based on RapidIO. Background Technology

[0002] In embedded system applications, all hardware components are connected via a bus. However, traditional interconnect buses, due to limitations in transmission bandwidth and system topology, can no longer meet the demands of ever-increasing processor frequencies and performance. Therefore, in embedded environments, the RapidIO interconnect bus protocol is primarily used to meet the interconnection and transmission needs between chips and boards, enabling communication speeds from 1Gbps to 60Gbps.

[0003] The amplitude of the RapidIO signal determines the signal strength and transmission distance. If the signal amplitude is too small, it may cause excessive signal attenuation during transmission, thus affecting the data reception quality. If the signal amplitude is too large, it may cause signal distortion at the receiving end, affecting the accuracy of the data. Therefore, proper adjustment of the signal amplitude is very important for ensuring the stability and reliability of communication.

[0004] When the RapidIO network is small, the default amplitude value of the RapidIO physical layer is sufficient. However, as the RapidIO network grows larger, the increased trace distance between the backplane and the controller, along with interference between physical chips, can lead to poor RapidIO signal quality. If the hardware is fixed, improving RapidIO signal quality can only be achieved by changing the speed of the RapidIO nodes, essentially performing a speed reduction. The drawback of this method is:

[0005] (1) Although the quality of RapidIO signal is improved after the rate is reduced, it may not meet the system's rate and bandwidth requirements.

[0006] (2) Even after reducing the rate, the RapidIO signal quality may still be poor, and the problem cannot be completely solved. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an amplitude adaptive method, device, medium and system based on RapidIO, which can solve the problem of poor RapidIO signal quality and the inability of RapidIO nodes to join the network due to hardware wiring in large-scale networks.

[0008] The objective of this invention is achieved through the following approach:

[0009] An amplitude adaptation method based on RapidIO includes:

[0010] By adaptively setting the amplitude of RapidIO, the optimal amplitude corresponding to the physical location of the module is sought through pre-emphasis settings and de-emphasis settings in sequence.

[0011] The optimal amplitude setting is used to improve the problem of poor RapidIO signal quality caused by hardware wiring in large-scale RapidIO networks, which prevents RapidIO nodes from joining the network.

[0012] Furthermore, the process of adaptively setting the RapidIO amplitude, sequentially through pre-emphasis settings and de-emphasis settings, to find the optimal amplitude corresponding to the physical location of the module, specifically includes the following sub-steps:

[0013] S100: During system initialization, the master control node scans the RapidIO nodes in the system, detects the RIO Port Error and Status CSR status of all ports of the SRIO switching chip, and judges the signal quality as poor if it is lower than expected, and performs multiple recovery operations.

[0014] After recovery, the main control node checks the RIO Port Error and Status CSR of the chip replacement port. If the signal quality is still poor, amplitude modulation is performed; otherwise, it directly connects to the network.

[0015] S300 enables the output amplitude of the transmitting end of the switching chip port;

[0016] S400: Set the local pre-amplification value sequentially. After each set number of times, reset and check the RIOPort Error and Status CSR status of the chip port. If the signal quality is greater than or equal to the expected value, it is considered good and can be connected to the network.

[0017] If the pre-weight setting fails, try setting the weight again. After each number of settings, reset the chip and check the RIO Port Error and Status CSR. If the signal quality is good, then connect to the network.

[0018] In the S600, the master control node records the amplitude values ​​corresponding to different switching ports in the corresponding amplitude table. Upon the next power-on, the master control node configures itself based on the values ​​in the amplitude table.

[0019] Furthermore, the multiple recovery operations specifically include performing three recovery operations.

[0020] Furthermore, the set number of times includes once.

[0021] A RapidIO-based amplitude adaptation device includes a processor and a memory, wherein the memory stores a computer program that, when loaded by the processor, executes the method described in any of the preceding claims.

[0022] A computer-readable storage medium storing a computer program that, when loaded by a processor, executes the method described in any of the preceding claims.

[0023] An amplitude adaptive system based on RapidIO includes the amplitude adaptive device based on RapidIO as described above.

[0024] The beneficial effects of this invention include:

[0025] (1) This invention provides a solution to the problem of nodes being unable to join the network due to poor RapidIO signal quality. By adaptively setting the RapidIO amplitude, the optimal amplitude corresponding to the physical location of the module is sought through pre-emphasis setting and de-emphasis setting. By setting the amplitude, the problem of RapidIO nodes being unable to join the network due to poor RapidIO signal quality caused by large-scale RapidIO networks and hardware wiring can be improved.

[0026] (2) This invention has the advantage of high efficiency. Specifically, it proposes a method to solve the problem of poor RapidIO signal quality caused by hardware wiring in large-scale RapidIO networks by reducing the bandwidth rate of RapidIO. The method provided by this invention optimizes the signal quality of RapidIO nodes without affecting the rate, and is more efficient and better accepted by users. Attached Figure Description
