摘要
An apparatus and a method of testing computer microarchitectures has a test writer create a test sequence written directly in microinstructions (both native-mode and emulation-only microinstructions). The microinstruction sequence is then inserted into a reprogrammable microcode storage, replacing the normal sequence of microinstructions for a given macroinstruction. In order to execute the microinstructions, the test writer can issue the macroinstruction. The method may be implemented in a simulation model where one set of microinstructions in the reprogrammable microcode storage can be easily replaced. The method may also be applied to an actual microprocessor implementation.
