TCAM (Ternary Content Addressable Memory) diversified configuration system and configuration method on the basis of FPGA (Field Programmable Gate Array) dynamic reconstruction technology

Abstract

The invention discloses a TCAM (Ternary Content Addressable Memory) diversified configuration system and configuration method on the basis of an FPGA (Field Programmable Gate Array) dynamic reconstruction technology. The TCAM diversified configuration system comprises an FPGA dynamic reconstruction unit, a dynamic reconstruction configuration unit, a control unit and a TCAM, wherein the FPGA dynamic reconstruction unit is used for carrying out dynamic reconstruction layout and generating a corresponding functional circuit so as to generate a corresponding dynamic reconstruction file after a pre-implementation function is converted to generate a corresponding dynamic reconstruction logic circuit; the dynamic reconstruction configuration unit is used for downloading and operating the dynamic reconstruction file and executing an action according to a control command of the control unit; and the control unit is used for monitoring the operation state of the TCAM communicated with the control unit in real time, sending a dynamic configuration command when the TCAM abnormally operates, and controlling the dynamic reconstruction configuration unit to reconfigure and repair the TCAM or carry out function reconfiguration to the TCAM. The FPGA dynamic reconstruction technology is utilized for reconfiguring the TCAM when the TCAM is out of order during use so as to achieve a purpose of repairing. The invention is simple in operation, and device resource use efficiency is improved.

Description

technical field [0001] The invention relates to a multi-configuration system and a corresponding configuration method for TCAM realized by using FPGA dynamic reconfiguration technology. Background technique [0002] With the rapid development of the network, TCAM is widely used in various fields, and people's demand for TCAM is also increasing. Although TCAM is powerful, its operation is relatively complicated. Generally, if you want to change the application function of TCAM, you need to use the host computer software to download its parameters with commands or pages. At this time, it is necessary to reset the TCAM; at the same time, after the reset, the TCAM will not work normally; at this time, it is necessary to reset the TCAM or even reset the whole machine, which is a fatal flaw for large systems. Usually, if we want to change the application function of TCAM, we need to take the corresponding equipment back and rewrite the program for debugging, which is time-consum...

Although TCAM is powerful, its operation is relatively complicated

Generally, if you want to change the application function of TCAM, you need to use the host computer software to download its parameters with commands or pages. At this time, it is necessary to reset the TCAM; at the same time, after the reset, the TCAM will not work normally; at this time, it is necessary to reset the TCAM or even reset the whole machine, which is a fatal flaw for large systems.

Usually, if we want to change the application function of TCAM, we need to take the corresponding device back and rewrite the program for debugging, which is time-consuming and labor-intensive.
