Device and method for operation of data

A data processing method, comprising:

• storing, by a storage module, a plurality of entries included in a first matrix and position information associated with each of the plurality of entries, wherein the first matrix includes a plurality of rows and a plurality of columns, and wherein entries included in each of the plurality of rows or each of the plurality of columns among the plurality of entries are grouped into a plurality of sets of entries;
• receiving, by a data load module, the plurality of entries and the position information from the storage module;
• generating, by the data load module, a determination result as to whether each of the received plurality of entries is zero;
• calculating, by the data load module, in each set of the plurality of sets of entries, a number of entries having a first value indicating that an entry is not zero;
• generating, by the data load module, an instruction sequence based on the determination result and the position information, wherein the instruction sequence includes one or more sets of instructions, a number of the one or more sets of instructions being equal to a largest number of the calculated number of entries;
• and
• generating, by a processing unit, an operation result by using a portion of the plurality of entries in accordance with the instruction sequence.
