According to the different problems that need to be solved each time, the government departments need to collect a large amount of data for analysis and judgment, and finally make corresponding administrative decisions.

[0003] However, with the increase in government affairs every year, many tasks even involve repeated data collection, which greatly wastes human resources. At the same time, each time a corresponding government decision is made, a lot of time is spent on re-analyzing basic data, summarizing rules, and deriving methods for government decision-making. This will undoubtedly increase the time cost of making government decisions and there is a problem of low efficiency. Therefore, there is an urgent need for a government affairs management method and system based on big data, which can assist decision-making through big data technology to solve the problem of waste of human resources each time data is collected and low efficiency in making government decisions.

If one of the data lines has sending data, then this data line is the sending line TX, and the other data line is the receiving line RX.

After receiving the operation instruction from the host computer, if it is judged to be a read operation, the state machine initiates an internal bus read operation. The single address mode of the read operation reads the internal bus once, and sends the read data out through the transmit line TX; if it is judged to be a write operation, the state machine initiates an internal bus write operation.
