Embodiment Construction
[0016] The multimedia navigator of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0017] The multimedia navigator of the present invention is provided with an emulation module, which can be used for debugging equipment by navigator developers, and it can be used by testers to test software without external hardware support, such as when there is no car. Frame simulation test CAN bus data. At the same time, it can also replace some laboratory test functions, such as random click stress test on the screen and buttons. The units involved in realizing this function of the multimedia navigator include a human-computer interaction module, a logic module, an operating system, a processor and a simulation module, such as figure 1 shown.
[0018] The main function of the human-computer interaction module is to feed back the user's operation results to the user, and to remind the user of the current...

The invention relates to a multimedia navigator. The multimedia navigator comprises a simulation module, wherein the simulation module exchanges data with a logic module and a middleware communication module in a mode of sharing internal memory, wherein both data exchange sides notify each other to perform data updating through a system event in a data exchange process, and communicate with external computer equipment through an embedded type serial communication interface, so that data received from the logic module and the middleware communication module is sent to the external computer equipment, the data obtained from the external computer equipment is analyzed and sent to the logical module or the middleware communication module. The multimedia navigator disclosed by the invention can realize simulation of the logic module, an operation system, a processor, other hardware in a car body as well as external equipment of the navigator. The development time and the test labor investment of a project are greatly reduced. The problem that software development team members depend on each other on development progress is solved.
Description
technical field [0001] The invention relates to a multimedia navigator. Background technique [0002] At present, the development and testing of the multimedia navigator requires complete hardware support to run. Therefore, the research and development personnel need to build a dedicated hardware testing platform to test the multimedia navigator. Different cars have different hardware platforms, so it is necessary to establish multiple corresponding hardware platforms, which is time-consuming, laborious, costly, and the progress of development and testing is slow. In addition, some manpower-based tests cannot be completed by building a hardware test platform alone, such as stress tests, robustness tests, random tests, etc., and other test equipment needs to be built. Contents of the invention [0003] The object of the present invention is to provide a multimedia navigator with a built-in simulation module, which enables the development and testing to be carried out under...
