Problems solved by technology

[0006] If it is impossible to make a soft emulator, it will not be able to provide customers with functional-level simulation and debugging tools in a timely manner. Customers must wait until the hardware emulator is completed before they can start software debugging. Objectively, the progress of software development will be greatly delayed, and the It is not conducive to the timely promotion of chip products

Embodiment Construction

[0012] There is one biggest difference between the simulation debugging process of the software on the emulator and the use on the product chip. When used in product chips, it cannot be ruled out that there are various possible data input to the coprocessor for calculation or processing, while the software simulation and debugging process is concerned with the function and correctness of the software itself, and only needs to provide several confirmations The input data that can be sent to the coprocessor for calculation or processing is enough to meet the requirements of debugging and checking the function and correctness of the software. And the software cares about the data input to the coprocessor and the correct response returned by the coprocessor, and does not care about how the coprocessor calculates or processes the input data. In addition, in order to hang the coprocessor on the hardware verification board to the processor core (generally implemented in the form of F...

Abstract

A method for realizing coprocessor in soft simulator includes embedding I / O data corresponding table obtained from hardware compressor chip[ into coprocessor module of soft simulator when software realization means of coprocessor can not be obtained and returning relevant response data back by coprocessor module after I / O data correspond table is queried according to inputted data when said coprocessor is operated by software.

Description

technical field [0001] The invention relates to a realization method of a coprocessor in a soft emulator. Background technique [0002] During the on-chip software development process of the microprocessor chip, it is necessary to use an emulator that is matched with the chip. Since it takes a long time to design and produce a hardware emulator, in order to seize the market as quickly as possible, chip manufacturers generally first produce and provide a soft emulator matching the chip. [0003] Although soft emulators are generally only used for functional-level simulation and debugging of software, in order to ensure that the developed program functions meet the requirements and the software can be quickly transplanted to the hardware emulator, the basic functions of the product chips simulated by the soft emulator are still required. Consistent with the definition in the product chip specification. These basic functions include the coprocessor function emulation in the c...
