A Novel Architecture for Embedded Database Management System on Chip

Abstract

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.

H/S Co-design of Embedded DBMS with High Speed Buffer Support

“…In our previous work [2], we present a novel architecture of embedded database. This architecture has performance advantage of SQLs execution because of its special database core, but the memory access is the bottleneck of DBoC.…”

“…Yet in the traditional way, they are same. Hence we must change the execution model researched in [2] and adopt a new flow to run the SQL command. The detail is showed as follow ( Figure 2): After the reset of computer, DBoC waits for the SQL commands.…”

“…Running with the recovery system disabled is faster than running with it enabled, since log records need not be written when changes are made to the database [4]. [2] is a novel architecture called DBoC we designed before for database. There is a special on chip core to deal with SQLs and in this architecture, a set of binary commands are defined as Database Management Language (DBML).…”

“…In the same time, embedded system and System-on-Chip(SoC) architecture are becoming commonly used in computing area, because of the low design cost and extensible architecture. We design a special system called DBoC (database on chip) in our previous paper [2], in which there is a special core for SQLs running. In this paper, we present a DBoC with high speed buffer support to accelerate the data access.…”

Implementation of an embedded database to portable measuring instruments

“…But this method has lost its superiority over an embedded database structure based on other types of memory chips. A back-end embedded database management system is brought forward [2], in which SQL demands are translated into binary demands before data operation and the data can be transplanted into portable computers. Sheikh suggested a three-layer embedded database management system, which can well be applied to high-end mobile instrument such as PDA [3].…”
