Embodiment Construction
[0167] The embodiment of the present invention provides an adapter, data transmission system and method, which can achieve the purpose of increasing the interface by increasing the number of adapter modules. If there is a new target device that needs to transmit data, there is no need to plug and unplug the already used cables. Instead, data can be transmitted directly through unused adapter modules, thereby improving cable switching efficiency, reducing labor costs, and reducing equipment hardware failures caused by frequent plugging and unplugging of cables, thereby realizing automation.
[0168]The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and not necessarily Used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the inven...

The embodiment of the present invention discloses an adapter, comprising: an access module obtains first frequency data through at least one first port, and sends the first frequency data to a switch module; the switch module obtains the first frequency data from the access module, And determine Y target adaptation modules in the M adaptation modules according to the preset correspondence, and send the first frequency data to the Y target adaptation modules; when receiving the first frequency data from the switching module, the adaptation The module performs frequency modulation on the first frequency data to obtain the second frequency data, and sends the second frequency data to the target device. The invention also provides a data transmission method and system. The present invention achieves the purpose of increasing the interface by increasing the number of adapter modules. If there is a new target device that needs to transmit data, it can be transmitted directly through the unused adapter module, thereby improving the efficiency of cable switching and reducing labor costs. , while reducing equipment hardware failures caused by frequent plugging and unplugging of cables.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to an adapter, a data transmission system and a method. Background technique [0002] In order to meet the increasingly complex chip design requirements, the scale of chip design has also increased dramatically. Among them, hardware accelerated emulation (English full name: Emulation), as a new technology for chip verification, has the advantages of fast compilation speed, large capacity, and strong ability to eliminate faults. In the Emulation application, there is a widely used in-circuit emulator (English full name: In-Circuit Emulator, English abbreviation: ICE) mode, which can compile the design to be verified (English full name: Design UnderVerification, English abbreviation: DUV) into hardware emulation tool (full English name: Emulator), and interconnect with an external target device for verification. [0003] At present, since the emulator generally operates at a ...
