Abstract
A system and associated method for distributing signals with efficiency over a microprocessor. A performance monitoring unit (PMU) sends configuration signals to a unit to monitor an event occurring on the unit. The unit is attached to a configuration bus and an event bus that are daisy-chained from PMU to other units in the microprocessor. The configuration bus transmits configuration signals from the PMU to the unit to set the unit to report the event. The unit sends event signals to the PMU through the event bus. The unit is configured upon receiving configuration signals comprising a base address of a bus ramp of the unit. A number of units and a number of events for monitoring is flexibly selected by adjusting a length of bit fields within configuration signals.
