Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] figure 1 is a schematic diagram of a network processor applied in the present invention;

[0021] The network processor includes a CPU and a microengine, and the activity detection task 101 is run on the CPU. The activity detection task 101 initializes the data area 102 for storing count values ​​for each microengine according to the number of microengines, and the microcode 103 running on the microengine A counter is set in , and the count value of the counter keeps increasing after the microengine runs.

[0022] figure 2 It is a method for network processor micro-engine activity detection provided by the invention, comprising the following steps:

[0023] 201. Create an activity detection task when the CPU is running.

[0024] 202. After the activity detection task runs, initialize the data area for storing count values ​​for ...

Abstract

The utility model relates to a method for micro-engine activity detection of network processor, which comprises the following steps: firstly, a processor creates an activity detection task, which is used for distributing the data area for respective micro-engine; secondly, a plurality of counters is arranged in the micro-engines; the count value of the counter is stored in the data area and is increased according to the operation times of the micro-engines . Thirdly, after the operation of the network processor, the activity detection task regularly scans respective data area. The count valueobtained in the scanning is compared with that of last scanning. If the results are same, the micro-engine is regarded as abnormal, which can be reset by setting relevant hardware register. The utility model has the advantages that the application performance of network processor can be improved better.

Description

technical field [0001] The invention relates to the field of processors, in particular to a method for detecting the activity of a micro-engine in a network processor. Background technique [0002] Due to the emergence and wide application of voice, image and multimedia services in the Internet, the traffic volume of the Internet is increasing at an exponential rate, and the rapidly growing Internet traffic volume has put forward new requirements for the existing network bandwidth. In order to meet these new requirements, major network equipment providers have invested in research and development of network equipment above Gigabit / 10G (1G / 10G) level and quickly seized the market. However, due to the rapid development of the network, the life cycle of network equipment is getting shorter and shorter, resulting in increasing pressure to frequently update existing equipment. In order to change the frequent update of traditional network equipment, network processors have entere...
