Abstract
A hardware task change system for the reduction of task change processing overhead delays in computer architectures includes an electronic circuit that switches data or tasks in multitasking computer architectures or other data processing circuits with minimal time delays. The system switches tasks by selecting the next task to run from the main working register set, the alternate register set, or the task storage memory. The working register has no multiplexer delay to the Central Processing Unit (CPU), and accomplishes this by connecting only one working register to the CPU instead of multiplexing two or more alternate working registers.
