Abstract
Certain embodiments of the present disclosure support a method and apparatus for efficient multithreading on a single core microprocessor. Thread switching in the single core microprocessor presented herein is based on a reserved space in a memory allocated to each thread for storing and restoring of registers in a register file. The thread switching is achieved without full save and restore of the register file, and only those registers referenced in the memory are saved and restored during thread switching.
