Method and device for downloading and analyzing program package, terminal equipment and storage medium

The invention relates to the technical field of intelligent cards, and discloses a method and device for program package downloading analysis, terminal equipment and a storage medium, and the method comprises the steps: starting program package downloading; wherein the program package is divided into n data blocks; the ith block of the program package is downloaded, and i = 0, 1,..., n-1; analyzing the ith block and storing the ith block into a cache space of a pre-applied volatile memory (VM); the ith block of the cache is written into a non-volatile memory (NVM) to be stored; and continuing to download the (i + 1) th block, and performing circular processing. According to the method, the downloading and analyzing time of the application program of the card supported by the NFC SE can be shortened. 本申请涉及智能卡技术领域，公开一种用于程序包下载解析的方法及装置、终端设备及存储介质，其中，所述方法包括：启动程序包下载；其中，程序包被划分为n个数据块block；下载程序包的第i个block，i=0，1，...，n-1；对第i个block进行解析并存入预先申请的易失性存储器VM缓存空间；将缓存的第i个block写入非易失性存储器NVM进行保存；继续下载第i+1个block，进行循环处理。本方法可以缩短NFC SE所支持的
