However, these characteristics of the emulator chip of the microcontroller have also brought some essential defects and deficiencies: (1) the framework of the emulator chip is based on a microcontroller with a certain architecture; (2) the use of the emulator requires certain The support of software and hardware; (3) The chip area of the emulator is larger than that of the microcontroller chip, and the number of pins of the emulator chip is larger than the number of pins of the microcontroller chip; (4) The emulator is mainly used for debugging and simulation, so the chip mass production will not be very large
[0004] Correspondingly, there are many single-chip emulators on the market, but they are mainly focused on general-purpose MCUs such as 51 series single-chip microcomputers and PICs. Some large companies also develop special emulators for their own products, but they are used for the simulation of handheld consumer electronics product development very few devices
At present, no emulator has been developed to complete the development and simulation of the kernel program of handheld consumer electronics products, nor is it able to provide users with a software development platform

Embodiment Construction
[0014] The present invention will be explained in more detail below in conjunction with the drawings and specific embodiments:
[0015] figure 1 It is a schematic diagram of the structure of the present invention. Such as figure 1 As shown, the present invention is composed of two parts: a peripheral computer and an emulator. The emulator is composed of three parts: a control board, an emulation board and a power supply. The peripheral computer controls the operation of the simulator by running simulation software and reads the simulation result; the control board downloads the user program according to the peripheral computer instruction, monitors the operation of the simulation board, and reports the running result to the peripheral computer; The simulation board is controlled by the control board, and runs the user target program or monitoring program in a single step or continuously; the power supply converts 220VAC mains into 9VDC, and supplies it to the simulator control ...

A microcontroller emulation system, its structure includes: a peripheral computer, a control board, an emulation board and a power supply. The emulator consists of three parts: control board, simulation board and power supply. The peripheral computer controls the operation of the emulator by running the simulation software and reads in the simulation results; the control board downloads the user program according to the instructions of the peripheral computer, monitors the operation of the simulation board, and reports the operation result to the peripheral computer; Emulation board, the emulation board is controlled by the control board, and runs the user target program or monitoring program in a single step or continuously; the power supply supplies power to the emulator control board. The invention is mainly applied to the simulation of microcontroller simulation chips.
Description
Technical field [0001] The invention relates to the field of electronic control devices, in particular to a microcontroller simulation system. Background technique [0002] Nowadays, products based on MCU (microcontroller) have occupied most of the consumer electronics field and are widely used in various fields, such as calculators, remote controls, voice coding, home appliance control and various toy circuits. The product has a long life cycle and broad market prospects. However, the development and application of microcontrollers are inseparable from an emulator based on the microcontroller. [0003] According to the publication specification of the invention patent application with the patent number 200510029285.2 filed on August 31, 2005, the simulator of the microcontroller has some characteristics: (1) It must be designed based on a certain microcontroller architecture; (2) It has a micro All the functions that the controller chip can realize; (3) Have certain microcontrol...
