As new applications of ubiquitous computing and ambient intelligence appear, there is great need to embed database technology into various lightweight computing devices. And the semiconductor industry allowing more and more transistors to be fabricated on a single silicon chip makes it possible to implement ever complex microelectronic system containing a CPU, embedded memory, I/O devices. In this paper, a novel architecture is proposed for a back-end Embedded Database Management System on Chip (DBoC) for lightweight computing devices. And in this architecture, a set of binary commands are defined as Database Management Language (DBML) named DBML command, a hardware solution for DBML Command Interpreter and a Data Flow Controller from Information Control Unit of Manticore are provided with.

Reconfigurable computing based on FPGAs (Field Programmable Gate Arrays) has been a promising solution to improve the performance with high flexibility. However, the physical capacity limitation of FPGAs prevents its wide adoption in real world. In this paper, a homogeneous NoCbased FPGA architecture is proposed, in which reconfigurable and I/O resources are interconnected via NoC so that reconfigurable modules can be placed anywhere once enough space available. Meanwhile, a virtual FPGA is proposed with which over large circuit can be implemented on a limited capacity FPGA. The experiment verified that our approach can provide more flexible reconfiguration, and combing NOC on FPGA, the resource utilization increased within 44.7%-53.5% because of the fragment in CRs benefit from such kind of dynamic partial configuration.
