Abstract
Systems and method include receiving counter update requests that are at a maximum frequency of f; sending the counter update requests to a main block of counters that operate at a maximum frequency of f, where (f)≥(f)/2; and responsive to a block of the main block of counters experiencing an overflow, sending corresponding counter update requests for the block of the main block of counters experiencing the overflow to a cache counter block that operates at a maximum frequency of f, where (f)≥(f) and (f)≥(f)−(f). The counter update requests can be for Y×K total counters, and the main block of counters can include Y blocks of counters each block having K counters, Y and K are positive integers. (f)≥(f)/2 ensures only one block of the main block of counters overflows simultaneously.
