Embodiment Construction
[0012] As shown in the figure, the emulator 1 for emulating special function registers of the present invention includes an emulation chip 2 and an emulator processor 3 . The emulation chip 2 includes a microprocessor core 4 consistent with the product chip, an SFR 6 implemented in a FIFO manner, and also includes a register 5 dedicated to implementing emulation functions. Register 5 and SFR6 communicate with the microprocessor core. Register 5 is a general-purpose register, and the register 5 stores the current read / write operation FIFO count pointer value of SFR6. There is an access channel between the emulator processor 3 and the emulator chip 2 , and the emulator processor 3 can read the data stored in the register 5 through the access channel. The simulator 1 is connected to the computer 7 , the simulator 1 can send data to the simulation interface on the computer 7 , and the computer 7 can also transmit the data on the simulation interface to the simulator 1 . The comp...
