Abstract
A trace array having features that provide reduced power consumption/power dissipation in processor circuits. The trace array circuit stores processor states during program execution and provides a resulting trace for subsequent analysis. The trace array includes power management features that, responsive to a control signal, reduce the power consumption of the trace array. A first state of the control signal indicates that the trace array circuit is storing states during the execution of the program and a second state of the control signal is set to enable the trace array for reading the collected states. The trace array may have dynamic read bit-lines and static write bit-lines to further reduce power consumption, and the pre-charge circuits that charge the dynamic read bit-lines may be selectively disabled in response to the first state of the control signal. Write-through may also be selectively disabled and optionally bypassed during state collection.
