Abstract

La presente invención, la cual pertenece al campo de la tecnología informática, proporciona un método y un dispositivo para comprimir un programa de firmware, y un método y un dispositivo para descomprimir un programa de firmware. El método incluye: adquirir una porción de código y una porción de datos del programa de firmware; comprimir la porción de código y la porción de datos por separado; y configurar primeros datos de descripción correspondientes al programa de firmware, en donde los primeros datos de descripción contienen primeros datos de dirección con respecto a dónde la porción de código comprimido se almacena en un dispositivo electrónico, segundos datos de dirección con respecto a dónde la porción de datos comprimidos se almacena en el dispositivo electrónico, una primera dirección de descompresión en donde la porción de código comprimido se va a descomprimir en el dispositivo electrónico, y una segunda dirección de descompresión en donde la porción de datos comprimidos se va a descomprimir en el dispositivo electrónico. Se puede resolver el problema en la técnica relacionada que después de que el programa de firmware se descomprime, se requiere que el dispositivo electrónico copie la porción de código descomprimido y la porción de datos, lo cual resulta en un proceso complejo. Además, se puede resolver el problema de que es complicado poder copiar códigos y el método de copiado tiene poca universalidad. Por lo tanto, se puede lograr un efecto de reducción de la complejidad del proceso del dispositivo electrónico al eliminar la necesidad de copiar códigos. (Figura 1).
