Embodiment Construction
[0018] As shown in the figure, the soft emulator 1 of the present invention includes a chip function simulation module 2 , a memory management configuration module 3 and a section of computer memory area 4 . The chip function simulation module 2 is used for simulating functions such as the processor core, peripherals, and coprocessors in the microprocessor chip. A section of computer memory area 4 is a section of memory in an address range that the soft emulator 1 applies to the operating system for simulating the memory of the microprocessor chip. Because the capacity of computer memory now has hundreds of MB to 1-2GB, the capacity of several MB at most is extremely sufficient relative to the memory of the microprocessor chip; The size of the memory area 4 is the maximum memory capacity that the microprocessor chip can support, and will not affect the use of the memory by the computer.
[0019] The processor core in the chip function simulation module 2 is connected with the...

The invention discloses a soft emulator which comprises a chip function analog module, a memorizer management and configuration module and a computer memory area. The memorizer management and configuration module can be configured by a user, the capacity and the type of a memorizer are selected, and the soft emulator conforming to the user requirements is formed through changing the configuration. The invention also discloses a realization method of the soft emulator. A novel soft emulator is not required to be newly manufactured by an IC manufacturer according to the user requirements, so that the cost investment of the IC manufacturer is reduced, and the user's trial efficiency and the conclusion acquisition timeliness are simultaneously improved, thereby facilitating the quick completion of profile definition of soft emulator chips and more quickly pushing the soft emulator a market.
Description
technical field [0001] The invention relates to a soft emulator used for simulation and debugging of microprocessor chips. The invention also relates to a method for realizing the soft emulator. Background technique [0002] In the on-chip software development process of the microprocessor chip (hereinafter referred to as the chip), it is necessary to use an emulator matching the chip. With the continuous promotion of microprocessor technology, the variety of manufacturers and microprocessors is also increasing. In order to seize the market at the fastest speed, it is necessary to develop an emulator matching the chip in a timely manner. Emulators currently used for chip on-chip software development include hardware emulators and soft emulators. [0003] It takes a certain amount of time to design and make a hardware emulator, and the cycle is long. The soft emulator does not involve the design and production of hardware and simulation chips, and its development work can...
