Method and device for software acceleration

The invention provides a method and a device for software acceleration. The method comprises determining whether software to be accelerated is included in a study result or not when the software to be accelerated is started; determining whether the currently opened file is a file required by the start-up of the software to be accelerated or not according to file names in the study result if yes; pre-fetching a pre-fetching buffer area of a stored memory of the opened files according to the file names, every time of file reading offset and every time of file reading length in the study result and establishing a file pre-fetching record table if yes; determining whether file data which need to be read are located in the pre-fetching buffer area or not according to the file pre-fetching record table when the opened files are read; copying the file data which need to be read from the pre-fetching buffer area so as to achieve the reading operation if yes. According to the method and the device for the software acceleration, the starting speed of the software can be significantly improved.
