可编程的数据流架构，具有灵活的可编程性的可重构体系结构

Reconfigurable architecture is considered as very efficient, and suitable for embedded applications. But the low utilize ratio of on-chip resources and lack of software programmability of traditional reconfigurable arrays draws the advantages back. We proposed a programmable dataflow architecture which consists of multiple configurable pipelines specially designed for symmetric-key blockciphers. With this new architecture, we achieved high resource usability and free software programmability at the same time.
