Embodiment Construction

[0013] As shown in Figure 1, the manufacturing method of the soft emulator of the present invention is, at first select a basic soft emulator 1 that is the same as the core characteristic of the target chip processor and that the SFR configuration is the closest, and on the basic soft emulator 1, add a Chip's soft emulation function layer 2. The basic soft emulator 1 and the soft emulation function layer 2 for the target chip together constitute a soft emulator 6 for the target chip. The soft emulation function layer 2 for the target chip includes a memory configuration module 3 corresponding to the specifications of the target chip, a coprocessor emulation function module 4 and an SFR emulation function module 5 .

[0014] When the special function registers in the target chip conflict with the special function register addresses and / or functions in the basic soft emulator 1, use the SFR extension function provided by the basic soft emulator 1 in the SFR emulation function mo...

Abstract

A method for preparing soft simulator includes adding a special function register simulation module in soft simulator when special function register in object chip is collided to special function register address in basic soft simulator, expanding out special function register function with collision in said module, intercepting operation down before basic soft simulator by said module when special function register of these address is operated by software then remapping and connecting operation onto expanded out special function register.

Description

technical field [0001] The invention relates to a manufacturing method of a soft emulator used for microprocessor chip emulation and debugging, in particular to a method for realizing the emulation function of a special function register (SFR) in the development process of the 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. 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 on-chip software development of microprocessor chips include hardware emulators and soft emulators. It takes a certain amount of time to design and produce a hardware emulator, and the cycle is longer; while the soft emulator does not i...
