Problems solved by technology

[0005] In this way, each branch processing module can only process a single data type. If a data type and data output port are added, the above mechanism needs to be added again, and the resource overhead is relatively large.

Embodiment Construction

[0015] In this specific embodiment, take the processing circuit with n input and 2 output as an example, such as figure 2 Shown: The N-input 2-output data transmission device includes:

[0016] N branch processing modules receive and process the input data, and divide the data into two categories according to the flag signal carried in the data frame;

[0017] Each branch processing module is connected with 2 random access memories (RAM), which are used to cache 2 different data types (0 or 1), and then generate a data sending request signal to the corresponding Polling queuing module;

[0018] Two polling and queuing modules of branch data perform polling and queuing for a certain type of data transmitted from different branch processing modules and then output to the subsequent stage, and one polling and queuing module processes one type of data.

[0019] In this specific embodiment, two random access memories (RAMs) are respectively used to cache different types of data ...

Abstract

The present invention provides multiple input / output data transmission device. It contains branching processing modules for to make receive processing to inputted data, data frame carried marking signal dividing data into M types; M branching data polling queuing module respectively to make polling queuing to different branching processing module transmitted one same type data then outputting to rear stage, one polling queuing module processing one type data, M polling queuing modules respectively outputting M types different data queuing results. The present invention reasonable and effective utilizes resource and raises systematical integration.

Description

technical field [0001] The invention relates to a data transmission device, in particular to a multiple-input multiple-output data transmission device. Background technique [0002] In the design of digital circuit interface, the system often encounters the situation of many-to-one front-end and back-level systems. At this time, it will encounter an N:1 queuing mechanism. The usual processing method is to process each branch separately, and then perform Unified queuing processing. Such as figure 1 Shown is a commonly used multi-point input, one point output (N:1) data transmission device, including: [0003] N branch processing modules, which are used for processing, timing adjustment and format conversion of the data sent by each branch input, and sending the data application to the subsequent polling queuing module; [0004] And a polling queuing module connected to all the N branch processing modules, used for performing polling queuing processing on the sent data requ...
