ABSTRACT:
For each programmable logic block in a programmable logic device, a programmable power and speed control circuit is programmably configurable to generate an output signal on a power and speed control line so that the static power consumption of the corresponding programmable logic block is adjusted to provide a particular combination of power and speed for that programmable logic block, i.e., a specific power/speed performance point. For each programmable logic block in the programmable logic device, a plurality of programmable selectable speed/power levels are provided by the programmable power and speed control circuit. This allows a distribution of programmable logic blocks in the programmable logic device that are powered to various performance levels to match more closely a distribution of performance requirements by the circuit that includes the various programmable logic blocks.
