<p>A processor uses multiple banks of an extended register set to store the contexts of multiple user-level threads. A current bank register provides a pointer to the bank that is currently active. A first thread saves its context (first context) in a first bank of the extended register set and a second thread saves its context (second context) in a second bank of the extended register set. When the processor receives an instruction for exchanging contexts between the first thread and the second thread, the processor changes the pointer from the first bank to the second bank, and executes the second thread using the second context stored in the second bank.</p> |
