Embodiment 1
[0035] see figure 2As shown, it is a schematic flowchart of Embodiment 1 of the method for monitoring abnormal image processing based on the QSYS system of the present invention. Such as figure 2 As shown, the monitoring method for abnormal image processing based on the QSYS system in this embodiment includes the following steps:
[0036] Step S201: Detect whether the target signal in the AvalonST data stream signal of the current IP module of the QSYS system is low level, if so, enter step S202;
[0037] Among them, the target signal includes any one or more signals in any of the above-mentioned data_valid, sop, eop, and st_ready, but in order to facilitate detection, it is generally selected to detect one of the signals in data_valid, st_ready;
[0038] Step S202: Timing the time when the target signal is at a low level to obtain a duration, and when the duration is greater than a preset time threshold, enter step S203;
[0039] Start timing when the target signal is de...
Embodiment 2
[0047] see Figure 4 As shown, it is a schematic flowchart of Embodiment 2 of the method for monitoring abnormal image processing based on the QSYS system of the present invention. In this embodiment, the target signal is the st_ready signal, and based on the detection of the st_ready signal, the judgment of whether the IP module is in the hang-up state is implemented as an example for illustration.
[0048] Considering that when the IP module of the ST stream link is running normally, the st_ready signal is at a high level most of the time, even if no video signal is input to the QSYS system, the st_ready signal will always remain at a high level, and it is always waiting The state of receiving data, when the IP module is not ready to receive data during the operation process, the st_ready signal becomes low level for a short time (up to 200 milliseconds in the case of passing), and when the internal operation processing is completed, the st_ready signal It will automaticall...
Embodiment 3
[0058] see Figure 5 As shown, it is a schematic flowchart of Embodiment 3 of the method for monitoring abnormal image processing based on the QSYS system of the present invention. The difference between the present embodiment and the second embodiment is that the target signal is the data_valid signal, and based on the detection of the data_valid signal, the judgment of whether the IP module is in the hang-up state is implemented as an example for illustration.
[0059] Such as Figure 5 As shown, the monitoring method for abnormal image processing based on the QSYS system in this embodiment includes the following steps:
[0060] Step S401: Obtain the information of whether the QSYS system has a signal source input by reading the decoding chip. If there is a signal source input, check whether the data_valid signal output from the IP module of this level to the IP module of the next level is low level, if it is low level, enter the step S402;
[0061] In this embodiment, be...
