Storage method for storage configuration parameters of external memory and related equipment

The embodiment of the invention provides a storage method for storage configuration parameters of an external memory and related equipment, and the method comprises the steps: reading a configuration parameter index table from an internal memory, the configuration parameter index table defining a value range of each data item in a plurality of data items and a target bit number required for expressing a numerical value in the value range; executing the same operation as the first data item for each data item in a plurality of data items in the internal memory: determining a target bit number required by a first storage value of the first data item according to the configuration parameter index table, the first data item is any one of a plurality of data items in the internal memory; and storing the first storage value of the first data item into an external memory according to the target bit number. According to the invention, the storage data can be stored in the external memory according to the required tar
