DYNAMIC PRESCALING COUNTERS

摘要

A prescaling counter includes a prescaling unit and a counter. The prescaling unit includes a programmable divider that is arranged to divide an event clock that includes signaled events to generate a prescaled clock in response to a prescaling value. The counter includes a register that includes a lower count register and an upper count register for generating a count result. The counter is arranged to increment the lower count register in response to the prescaled clock and to increment the upper count register in response to a terminal condition in the lower count register. The prescaling value is generated in response to the upper count register.
