Abstract
A content search system including a CAM device having a plurality of CAM blocks and a governor logic receives a search request and compares the number of CAM blocks required to perform the requested search to a limit number, the limit number being the maximum number of CAM blocks permitted to be used in a requested search operation. If the number of CAM blocks required to perform the requested search exceeds the maximum number of CAM blocks permitted to be used in a requested search operation, then the search operation is rejected. The governing operation can be performed on each requested search, thus limiting power dissipation. The relationship between a maximum number of CAM blocks and power dissipation can be characterized, and a corresponding block limit value can be stored into a memory accessible by governor logic.
