Method and device for processing hardware table entry checking error

Abstract

The invention discloses a method for processing a hardware table entry checking error. The method comprises the following steps of: acquiring the hardware table entry checking error information of a device in a checking information register of the device; judging whether the frequency of address errors in the hardware table entry checking error information exceeds a threshold value in a preset time span according to the hardware table entry checking error information; if so, determining that the device fails; otherwise, determining that the device does not fail; when the device fails, determining an index of error hardware table entries according to the hardware table entry checking error information; and querying corresponding software table entries according to the index of the error hardware table entries, refreshing the error hardware table entries according to the queried software table entries, determining that new hardware table entry checking error information is not recorded in the checking information register of the device in a second preset time span, and maintaining the working condition of the device. By the method, the reliability and maintainability of a system are improved.

Description

technical field [0001] The invention relates to the field of communications, and in particular, to a method and device for processing hardware table entry verification errors. Background technique [0002] ECC (Error Correcting Code, Error Checking and Correcting) memory refers to the memory that applies EEC technology, which is generally used in servers and graphics workstations to make the entire computer system more secure and stable at work. [0003] Before the advent of EEC technology, the most widely used technology in memory was Parity (parity check) technology. In a digital circuit, the smallest unit of data is a bit, also called a data "bit". A bit is also the smallest unit in memory. It uses "1" and "0" to represent data high and low level signals. . In digital circuits, 8 consecutive bits are a byte. In the memory without "parity", each byte has only 8 bits. If one of its bits is stored incorrectly, the corresponding data stored in it will be changed and the ap...

Problems solved by technology

But the shortcoming of Parity is: when the memory finds a data bit error, it may not be able to determine which bit, and it may not be able to correct the error.

[0007] The current hardware entry verification method has been widely used in various devices, but because Parity cannot correct errors, and ECC can only correct single-bit errors, in the prior art, there is no way to detect hardware entry verification The recovery mechanism after an error causes the entire forwarding board to be replaced after a hardware entry check error is detected
