Domain-oriented software defined computing architecture

With the introduction of software defined hardware by DARPA Electronics Resurgence Initiative, software definition will be the basic attribute of information system. Benefiting from boundary certainty and algorithm aggregation of domain applications, domain-oriented computing architecture has become the technical direction that considers the high flexibility and efficiency of information system. Aiming at the characteristics of data-intensive computing in different scenarios such as Internet of Things (IoT), big data, artificial intelligence (AI), this paper presents a domain-oriented software defined computing architecture, discusses the hierarchical interconnection structure, hybrid granularity computing element and its computational kernel extraction method, finally proves the flexibility and high efficiency of this architecture by experimental comparison.
