LongRun

from Wikipedia, the free encyclopedia

LongRun and LongRun2 are power-saving technologies from Transmeta , comparable to Cool'n'Quiet from AMD or Speedstep from Intel . Transmeta developed these technologies to use in their own processors. LongRun was introduced with the Crusoe , LongRun2 with the Efficeon processor. On April 1, 2005, Transmeta officially announced that it no longer wanted to develop any further processors and would instead concentrate on the development of future-oriented technologies such as: B. LongRun2. LongRun2 has previously been licensed to Fujitsu , NEC , Sony , Toshiba and Nvidia .

LongRun is mainly based on a dynamic but very aggressive reduction of the frequency and voltage of a processor to lower power consumption. LongRun2 goes one step further and intervenes in the manufacturing process of the processors. As processors have ever smaller structures, they increasingly have to deal with leakage currents . These increase the power consumption of the processors without increasing their performance. Leakage currents can be minimized through intelligent manufacturing processes.
