Linux Bootup Time Reduction for Digital Still Camera

Bootup time is a very important issue in the DSC System because customers want to capture immediately specific image. In this paper, we present the experience of the implementation methods and the performance evaluation results for reduction of bootup time which was used in SAMSUNG DSC platform. At first we introduce the DSC platform and development environments and next we explain the optimization method for the bootloader and the kernel bootup time. We also describe root file system, device driver module configuration and DSC applications initialization for bootup time. There are various techniques for linux bootup time reduction and we explain the most important differences.
