High-reliability data rate processing system, method and equipment

The invention belongs to the field of data transmission, and particularly relates to a high-reliability data rate processing system, method and equipment. The objective of the invention is to solve the problem that only a basic unit with a fixed rate exists in a general library and circuit function requirements cannot be directly realized in the prior art. The system comprises a cross-clock domain processing module used for carrying out asynchronous processing on input data; the pointer controller is used for acquiring a read-write pointer control signal; the data preprocessing module is used for preprocessing the input data subjected to asynchronous processing; the data conversion and cache module is used for performing conversion output and data read-write processing on the input data subjected to asynchronous processing to obtain second data; and the data screening module is used for adding check bits to the second data to obtain third data, comparing corresponding check bit values of the first data and th
