In a data processing system employing microcode techniques, complex sequences of microinstructions can be initiated by application of a single macroinstruction. These complex sequences of microinstructions are typically noninterruptible and therefore the execution of a macroinstruction is atomic (i.e. executed as a single entity). Data processing systems that do not employ microcode typically have simpler macroinstruction sets that do not provide for a similar atomicity for complex instruction sequences. In order to obtain the same atomicity of instruction execution and to provide a nonmicrocoded data processing system with the capability to execute complex instruction sequences as an …
