Abstract The invention discloses an implement method for MAC (Media Access Control) address lookup tables in an FPGA (Field Programmable Gate Array). The implement method comprises the following steps of: rationally arranging a data organization structure of each lookup table; giving overall consideration to index value conflicts and a lookup speed of each lookup table, and setting a corresponding rational MAC address number for each index value; splitting the lookup tables, and aging the split lookup tables one by one in an aging logic to effectively reduce consumption of a logical resource; and plugging in a small-capacity CAM (Central Address Memory) to further prevent the index value conflicts. The implement method for the lookup tables provided in the invention uses as less logical resource as possible to achieve the advantages of the lookup tables, and has the advantages of high table lookup speed, a little occupied logical resource, high expandability and the like.
