Systems and methods for improving data restore overhead in multi-tasking environments

摘要

A computer processing system includes a central processing unit (CPU) and logic instructions operable to, when a task ready to be scheduled for execution in the CPU (402) is the same as a task yielding to the task ready to be scheduled (406-Y), retain context information for the yielding task in background registers in the CPU, and move the context information for the yielding task directly from the background registers to foreground registers in the CPU for the task ready to be scheduled (410). The task ready to be scheduled is executed using the context information in the foreground registers (316).
