Abstract
A data processing system comprises first and second arithmetic units for processing emergent tasks and non-emergent tasks, respectively, a memory for storing the data from the arithmetic units, and a control unit. The control unit selects either an interrupt task or a task being processed in response to the priority levels of the tasks. The first or second arithmetic unit is operated in response to whether a selected task is an emergent task or a non-emergent task.
