Problems solved by technology

Many new microcontrollers contain caches that are invisible to the emulator, and the internal clock rate is generally several times higher than the bus rate. It has become more and more difficult to emulate with an external in-circuit emulator instead of the target processor.

Description

technical field [0001] The invention relates to a micro-controller embedded online simulation debugging system, which belongs to the field of semiconductor integrated circuit design. Background technique [0002] In the development process of the application system with the microcontroller as the core, the various functions of the chip must be tested and verified by the online emulator system at the design stage of the chip; while in the application field of the application system with the microcontroller as the core , more inseparable from the in-circuit emulator system to monitor and control the chip internally, therefore, the in-circuit emulation debugging system is an important tool for application system development and debugging. Usually, in the field of engineering, an external in-circuit emulator is used to scan and test the program memory and the inside of the chip. The external chip emulator is roughly divided into two ways: [0003] (1) The emulation head of the...
