Abstract
An apparatus and method for reducing power consumption in a programmable logic device (PLOD) having multiple logic blocks and macrocells. Power consumption is reduced by detecting programmable switch values in each macrocell and generating a clock control signal based on the switch values. The clock control signal controls a macrocell buffer used for compensating for distortion of clock signals inputted to the macrocell. The macrocell buffer is disabled if the clock signals are not being used by the corresponding macrocell, thereby preventing unnecessary toggling and power consumption.
