A multithreaded processor device is disclosed and includes a plurality of execution units to execute a plurality of program threads and includes a global low power detection circuit. A method of forming a distributed Bragg reflector includes forming a first layer to be a first thickness and forming a second layer to be a second thickness. The shifter receives a shift control input, where the shift control input is pre-computed as equal to the integer portion of 2 raised to the base-2 logarithm of the gain of the CIC filter.
