Embodiment Construction

[0049] This embodiment realizes the reading and writing of the simulated chip register or memory based on the model of realizing the specific functions of the chip by sending commands. channels; after the analog channel receives the command, it processes the command in the simulated chip environment. The chip environment is not a real chip, but uses the memory in the host computer to simulate the chip's registers and / or memory.

[0050] Such as figure 1A system for simulating chip operation in this embodiment shown includes: an application program module 10, which is used to provide users with an operating platform for sending and receiving commands to realize specific functions of the chip; a driver program module 11, which is used to be applied The program module 10 invokes and sends commands to operate the chip in the form of commands, which can be read and write chip register commands, read and write chip memory commands, or other operating commands; the public communicat...

Abstract

The invention discloses a method and system to simulation chip operation which can be used to verify the function of chips and software architecture through the simulation the operations of chips at the absence of real chips to resolve the problem of long cycle of chips and driver software development in existing technology. In the method, the application module on the host calls the driver module of the chip to send the first command to the public communication platform. The public communication platform analyzes the first command, generates the second command that can be identified by the chip, and sends the second command to the chip simulation module on the host through simulation channel. The chip simulation module analyzes the second command and implements corresponding operations. Using the invention can accelerate the development of chip and driver software product.

Description

technical field [0001] The invention relates to embedded development technology in the computer field, in particular to a method and system for simulating chip operation. Background technique [0002] In the existing embedded development technology, the more general development model has the following two situations: [0003] The first model is that all the programs run in the embedded environment, and the user completes specific tasks through some buttons, touch screens, etc., or the host uses Uart (Universal Asynchronous Receiver / Transmitter) SerialBus) and other channels send simple commands to complete specific tasks, which is embedded development in the traditional sense, such as mobile phone development. [0004] The second model is that there is only the most basic program operating environment in the embedded environment, mainly including register read and write, memory read and write, device initialization and interrupt service routine, etc. The host sends read and...
