Problems solved by technology
When the processor performance is low and the memory space is limited, the communication protocol stack cannot be implemented, and Ethernet communication cannot be performed
For example, in some electronic systems using traditional 8-bit or 16-bit single-chip microcomputers, it is difficult to use Ethernet for communication, which cannot meet the needs of electronic system networking and integration
However, in the current existing technology, there is no specific method for hardware programming of the UDP / IP protocol stack, and no in-depth research on how to reduce the time overhead of the communication protocol stack

The invention discloses an Ethernet communication protocol stack system and an implementation method. The MAC data arbitration module is used to analyze the received data to obtain the data type of the received data, and then the data of different types is verified by using a proprietary module, and the IP is used to receive the data. The module, ARP receiving module or ICMP receiving module respectively unpacks different types of data, adopts real-time verification to reduce the time overhead of the protocol stack, and finally uses the MAC data arbitration module to send the IP sending module, ARP sending module and ICMP The data sent by the module is sent by priority arbitration. The invention has the advantages of simple structure, low delay, easy expansion, and simple implementation. When transmitting data, the verification is performed synchronously, which takes less time. The logic design is mapped to the programmable logic device for realization, and The function of the protocol stack is tested, and the test results show that the present invention has good implementability, and the performance meets expectations, and is suitable for the field of Ethernet communication without a standard software protocol stack.
Description
technical field [0001] The invention relates to an Ethernet communication protocol stack designed by an all-digital circuit, in particular to an Ethernet communication protocol stack system and a realization method. Background technique [0002] The current way of using Ethernet communication is mainly to use the software standard TCP / IP communication protocol stack on the CPU platform to communicate with other Ethernet devices. The premise of this communication method is that there is a processor with higher performance. When the performance of the processor is low and the memory space is limited, the communication protocol stack cannot be implemented, and Ethernet communication cannot be performed. For example, in some electronic systems using traditional 8-bit or 16-bit single-chip microcomputers, it is difficult to use Ethernet for communication, which cannot meet the needs of electronic system networking and integration. However, in the current prior art, there is no ...
