Abstract
In a preferred embodiment of the present invention an a method whereby a pipelined data processor with an embedded microinstruction sequencer can give special consideration to the interrupt of the microinstructions translated from a macroinstruction using two control bit data, accelerate the reaction time to interrupts, and expand the time frame within which to process interrupts while maintaining a precise interrupt. When a macroinstruction is decoded into microinstructions at the decoder stage in a pipelined data processor, a control bit called the atomic bit provides the system with the information about the boundary of the precise interrupt, and another control bit called the LOCK bit decides when an external interrupt can be processed and masks an interrupt when the system state does not allow any interrupt to be processed.
