Abstract

The present invention provides a method for reading input information, a circuit, a storage medium, and an electronic device, wherein the method includes: for each processor in a processor system including m processors, for each Each processor expands n serial ports, so that the output serial port of each processor is at least connected to the input ports of the extended serial ports of n-1 other processors in the processor system, wherein m is greater than A positive integer of 1, n is a positive integer greater than 1 and less than or equal to m; respectively read the input information of the n serial ports extended by each processor, and adopt the above technical solution to at least solve the problem in the related art For multi-processor operating systems, when some of the processors are abnormal, the serial port output information of the processors is easy to lose and other problems.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for reading input information, a circuit, a storage medium, and an electronic device. Background technique [0002] In current multi-processor computer systems (such as multi-CPU general-purpose server systems, multi-controller storage servers, and multi-CPU heterogeneous systems), system reliability is very important. The serial port is an important means of debugging and troubleshooting in the processor system, and its reliability is particularly important. For the technical solution of debugging through the serial port, the related technologies mainly include: [0003] 1) if figure 1 As shown, the sharing or switching technology between multiple serial ports is used to save the space of the serial port interface and achieve the purpose of serial port multiplexing, but only one serial port can be used at the same time. In addition, it needs to rely on external debugg...
