Compression progress information of the compression identification component.
具体地，在本步骤中，当其它任务有需要打印的待打印日志时，通过调用打印任务的接口函数，来通知打印任务，待打印日志的总长度和内容。当打印任务运行时，会检测当前待打印日志的长度是否为零；如果不为零，则对待打印日志进行压缩，并更新压缩标识组件的压缩进度信息，如该压缩进度信息可以包括压缩是否完成，以及压缩当前的进度，如压缩完成几个等等。Specifically, in this step, when other tasks have logs to be printed that need to be printed, the printing task is notified of the total length and content of the logs to be printed by calling the interface function of the printing task. When the printing task is running, it will detect whether the length of the current log to be printed is zero; if it is not zero, the log to be printed will be compressed, and the compression progress information of the compression identification component will be updated. For example, the compression progress information may include whether the compression is completed. , as well as the current progress of the compression, such as the completion of the compression and so on.
步骤S230、响应于所述压缩标识组件指示的压缩进度信息为压缩完成信息，对压缩后的待打印日志进行打印。Step S230, in response to the compression progress information indicated by the compression identification component being compression completion information, print the compressed log to be printed.

具体地，在本实施方式中，在进行存储新的待打印日志时，为了避免存储空间浪费，存储空间组件可以采用循环存储的方式存储待打印日志，也即如果存储的位置到达了存储空间的尽头时，则下一个内容会存储于存储空间的开头。Specifically, in this embodiment, when storing a new log to be printed, in order to avoid wasting storage space, the storage space component can store the log to be printed in a cyclic storage manner, that is, if the storage location reaches the limit of the storage space At the end, the next content will be stored at the beginning of the storage space.
在一些实施方式中，所述方法还包括：In some embodiments, the method further includes:
设定打印任务的优先级低于所述其它任务的优先级。The priority of the print task is set lower than the priority of the other tasks.

In response to the total length of the log to be printed is greater than the compression threshold, the log to be printed is compressed in stages.
具体地，在本步骤中，每次压缩的长度有最大值限制，比如128个字节，如果待压缩的日志长度大于128个字节，则需要分两次或多次进行压缩。Specifically, in this step, the length of each compression has a maximum limit, such as 128 bytes. If the length of the log to be compressed is greater than 128 bytes, it needs to be compressed in two or more times.
本实施例的日志打印方法，在压缩之前，先判断待压缩的日志长度是否大于压缩阈值，并在大于压缩阈值时采用分批次压缩，从而可以提高压缩速度和压缩效率，避免因日志长度过长且采用一次压缩导致的系统崩溃或异常问题发生。In the log printing method of this embodiment, before compressing, it is judged whether the length of the log to be compressed is greater than the compression threshold, and when it is greater than the compression threshold, batch compression is adopted, so that the compression speed and compression efficiency can be improved, and the excessive log length can be avoided. System crashes or abnormal problems occur due to long and one-time compression.
在一些实施方式中，所述压缩标识组件包括压缩完成标识和压缩进度标识。所述更新所述压缩标识组件的压缩进度信息，包括：根据待压缩总数和压缩完成数量，更新所述压缩进度标识；以及，在压缩完成时，将所述压缩完成标识设置为第一预设值，未完成时，将所述压缩完成标识设置为第二预设值。In some embodiments, the compression indicator component includes a compression completion indicator and a compression progress indicator. The updating the compression progress information of the compression identification component includes: updating the compression progress identification according to the total number to be compressed and the compression completion quantity; and, when the compression is completed, setting the compression completion identification as a first preset If not completed, the compression completion flag is set to a second preset value.
具体地，在本步骤中，压缩是否完成用0或1来表示，1表示完成，0表示未完成。压缩进度用2个数字表示，分别是待压缩的总数，和已经完成的数目，比如待压缩总数是5，已完成是2，那么是否完成标志就是0，如果待压缩总数是5，已完成是5，那么是否完成标志就是1。Specifically, in this step, whether the compression is completed is represented by 0 or 1, 1 represents completion, and 0 represents not completed. The compression progress is represented by 2 numbers, which are the total number to be compressed and the number that has been completed. For example, the total number to be compressed is 5, and the completed number is 2, then the completion flag is 0. If the total number to be compressed is 5, the completed number is 0. 5, then the completion flag is 1.
在一些实施方式中，在打印完成所有的待打印日志之后，所述方法还包括：In some embodiments, after printing all logs to be printed, the method further includes:
清除存储空间组件中存储的打印日志，并重新设置所述打印任务中的打印标识组件和压缩标识组件。The print log stored in the storage space component is cleared, and the print identification component and the compression identification component in the print task are reset.
具体地，在本步骤中，当打印任务完成了所有的日志打印后，其重新设置任务中保存的打印标识组件和压缩标识组件，以使后续其他任务的日志存放在合理的位置。Specifically, in this step, after the printing task completes all log printing, it resets the print identification component and the compression identification component saved in the task, so that the logs of other subsequent tasks are stored in a reasonable location.
在一些实施方式中，所述输出打印完成的日志内容，包括：In some implementations, the outputting of the log content after printing includes:
通过直接调用寄存器的读写函数，输出打印完成的日志内容。By directly calling the read and write functions of the register, output the log content after printing.
具体地，在本步骤中，直接调用寄存器读写函数来发送数据，所花时间少于调用库函数发送数据的时间，原因是库函数比较复杂，因此，打印任务最终输出日志时，不会调用标准的库函数，而是直接调用寄存器的读写函数，以提高打印的效率。Specifically, in this step, directly calling the register read/write function to send data takes less time than calling the library function to send data. The reason is that the library function is more complicated. Therefore, when the print task finally outputs the log, it will not be called. Standard library functions, but directly call the read and write functions of registers to improve the efficiency of printing.
