A method of processing multimedia data includes: separating a defined application kernel into a data patch kernel and a data processing kernel; requesting, by the data processing kernel, access to patch data of the multimedia data, from the data patch kernel; performing, by the data patch kernel, an operation that is independent of the request and preparing data for the data access based on the request; and performing, by the data processing kernel, an arithmetic operation on work items of the prepared data when the data has been prepared by the data patch kernel.
