Problems solved by technology

However, this solution has the following disadvantages. First, the general-purpose emulator software does not read the ID number from the emulator hardware and perform a comparison process, so the general-purpose emulator software can still connect to the emulator hardware normally and perform debugging; secondly, by comparing chips The handshake mechanism of the emulator ID number is simple to implement, and the security is not enough

Abstract

The invention discloses a CPU chip simulator supporting debugging authority control. The CPU chip emulator comprises a simulator hardware and a simulator software, the simulator hardware comprises a mainboard, the mainboard comprises a power supply module, a chip prototype and a debugging line, and a debugging permission control module is arranged in the chip prototype; the simulator software is in communication connection with the simulator hardware through a debugging line, and a debugging permission operation module is arranged in the simulator software; wherein the simulator software operates the debugging authority control module in the simulator hardware through the debugging authority operation module, so that the opening or closing of the debugging authority of the simulator hardware is realized. Therefore, the CPU chip simulator supporting the debugging authority control is simple and reasonable in structure, and a handshake operation realization mechanism of the simulator software and the simulator hardware is safer.

Description

technical field [0001] The invention relates to the technical field of chips, in particular to a CPU chip emulator supporting debugging authority control. Background technique [0002] The emulator is a system that simulates the functions of the CPU chip and realizes the debugging of the CPU chip program. Here, the CPU chip is a chip that has a CPU and can execute embedded programs. According to the different implementation methods of the target chip, emulators can be divided into hard emulators and soft emulators. The target chip of the hard emulator is implemented by hardware, generally using FPGA; the target chip of the soft emulator is implemented by software. [0003] For different types of chips of the same CPU core, the same emulator software can often be used, but the emulator hardware will be different due to the different types of chip prototypes solidified in the motherboard, so the emulator hardware corresponds to a certain type of chip. [0004] In general, an ...
