摘要： A method for managing a content addressable memory (CAM) look-up table using the longest prefix matching (LPM) is provided. The method includes providing a pair of pointers per every band of data having the same prefix in length, wherein one of the pair of pointers stores the address of data having the lowest address in each band of data, and the other pointer of the pair of pointers stores the next higher address of data having the highest address in each band of data; and making a space in which data is to be added in the CAM look-up table by moving data having the addresses stored in the pair of pointers provided per each band of data that has a shorter prefix length than the prefix length of the data to be added, when data is added to the CAM look-up table. According to the method, it is possible to easily and efficiently add new data into the look-up table of the CAM.

摘要： A router, which is basically a point-to-point communication router, is devised for the BUS-like communication between processors. Therefore, it is named as ‘Virtual Bus’. One processor is connected to one router and the router can be connected in one dimensional array or two dimensional arrays. In case of two dimensional arrays, there are row and column router controllers. The method of communication consists of two phases: Firstly, the path between source processor and destination processor by sending set-up message. Secondly, messages are transferred without intervention of the intermediate routers between the source and destination processors. The idea is that the intermediate routers are set up to by-passing mode at the set-up phase. That is the routers in by-passing mode just relay the incoming messages to their output ports without any interruption. Therefore the virtual bus can guarantee high speed communication between processors. This method is equally applied to the two or more dimensional arrays.
