Digital platform plays a vital part both in managing enormous product data, project team and assignment for the development of virtual prototype. In this paper, aiming at digital platform supporting gun virtual prototype design, the framework of digital platform is designed. The management of product structure and authority is studied; the solution of drawing files view online is proposed. Judging from the feedbacks, digital platform could efficiently support the thorough management of gun virtual prototype design.
Processors using stream architecture can make good use of the on-chip resources and explore the data locality and parallelism. DES algorithm is one of the most popular cipher algorithms. This paper proposes the novel implementation of DES algorithm on stream architecture based on both stream programming model and DES algorithm and the speedup is 1.27 times.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
