Embodiment Construction

[0046] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0047] figure 1 It is a schematic diagram of an online memory test through a CPU provided by an embodiment of the present invention. figure 1 , the CPU monitors the packet receiving rate of the forwarding module in the NP, enables and disables the detection module inside the NP, and executes the copy operation of the entries in the forwarding table, and records the test results, etc. The NP includes a forwarding module and a detection module. The forwarding module is responsible f...

Abstract

The embodiment of the invention relates to a method and device for testing a memory. The method includes the following steps that: a first forwarding table stored in a first storage space of the memory is copied to a second storage space of the memory, so that a second forwarding table can be obtained; a network processor tests the first storage space; the second forwarding table stored in the second storage space is copied to the first storage space, so that a third forwarding table can be obtained; and the network processor accesses the third forwarding table, so that discovery of faults in the memory can be facilitated.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for testing a memory. Background technique [0002] The forwarding plane of the data communication device generally uses a network processor (network processor, NP). NP generally configures a large-capacity memory to store entries, including NP's internal memory and off-chip memory. After receiving the data packet, the NP will search for the corresponding entry according to the packet type and related configuration, and decide how to process the data packet according to the search result. The reliability of the memory will affect the normal processing of data packets. If the entry returned by the memory accessed by the NP is incorrect, it will cause the NP to process the data packet incorrectly, and ultimately affect the service application. Therefore, improving the reliability of the memory has become an urgent problem to be solved. [0003] In the prio...
