摘要： Embodiments of the present invention relate to an architecture that uses hierarchical statistically multiplexed counters to extend counter life by orders of magnitude. Each level includes statistically multiplexed counters. The statistically multiplexed counters includes P base counters and S subcounters, wherein the S subcounters are dynamically concatenated with the P base counters. When a row overflow in a level occurs, counters in a next level above are used to extend counter life. The hierarchical statistically multiplexed counters can be used with an overflow FIFO to further extend counter life.

摘要： A policer system on one or more place and/or route blocks. The policer system including a plurality of local physical policers each stored in a plurality of physical memory banks and coupled with a plurality of global policers stored in one or more global banks separate from the physical banks. Thus, each bank of the global policers are able to represent a logical combination of a plurality of the physical banks of physical policers.

摘要翻译： 本发明的实施例涉及使用分层统计复用计数器将计数器寿命延长数量级的体系结构。 每个级别包括统计上复合的计数器。 统计复用的计数器包括P个基本计数器和S个子计数器，其中S个子计数器与P个基本计数器动态连接。 当一个级别发生溢出时，上一级的计数器用于延长计数器的使用寿命。 分层统计复用计数器可与溢出FIFO一起使用，以进一步延长计数器的使用寿命。
