PARALLEL DOWNLOAD METHOD FOR INCREASING DOWNLOAD SPEED OF FIRMWARE FOR USE IN MULTI - MICROPROCESSOR MOBILE COMMUNICATION TERMINAL

摘要

The present invention relates to a parallel download method for improving the download speed of firmware in a multi-microprocessor mobile communication terminal.;The present invention provides a parallel download method for improving the download speed of firmware in a multi-microprocessor and a multi-flash memory environment of a mobile communication terminal performing multimedia functions including photographing, TV reception, gaming, and MP3 playback. (a) detecting reception of a packet through an interface module; (b) executing a download driver in a random access memory (RAM) of a main microprocessor among the multiple microprocessors; (c) downloading the firmware of the multiple microprocessors to the RAM of the main microprocessor by the download driver executed in step (b); And (d) storing the firmware of the multiple microprocessors downloaded to the RAM of the main microprocessor in the multi-flash memory at the same time in the step (c). Provides a parallel download method to improve the.;According to the present invention, since the download speed of the firmware controlling the hardware of the mobile communication terminal is improved by using the parallel download method, the production and development efficiency of the mobile communication terminal is increased, and new functions of the hardware of the mobile communication terminal are added to the firmware. When it is necessary to upgrade, the time required for upgrading is shortened.;Mobile Terminals, Multiple Microprocessors, Download Drivers, Firmware
