Dynamic energy management

A computer system with reliable dynamic energy management includes a thread synchronized energy configurator, the thread synchronized energy configurator extending an instruction decoder of the computer system and the thread synchronized energy configurator is disposed to append an energy configuration field including energy configuration bits to pipeline control bits of instructions in the instruction decoder, a thread synchronized dynamic frequency shifter (DFS), the thread synchronized DFS disposed to set control signals indicative of a frequency shift both per thread and per pipeline, and a thread synchronized general purpose register (GPR) super scaler, wherein the GPR super scaler is disposed to optimize thread operation based upon the set control signals.
