Abstract
A thresholding mechanism and method for performance monitoring of memory array access distribution times is disclosed. A data request signal sent to the memory hierarchy activates a first counter, having a first count value. A clock coupled to the first counter increments the first count value with each clock cycle, while also decrementing a decrementer having a predetermined threshold value. The first counter is deactivated by a completion signal when the data request is completed. A second counter having a second count value is incremented when the first count value is greater than the threshold value by the time the data request is complete.
