System On Programmable Chip

For years, DSP has been the dominant tool in implementing gate switching for power inverter. It is a powerful and reliable technology in carrying out complex switching schemes. DSP is still expensive due to its intensive use of resource in chip fabrication. There is no flexibility in making change on hardware once a DSP chip is selected. It is also time consuming in a design development because the learning curve of the DSP is stiff. Recently, a new approach to the problem has emerged. It is called embedded system design. Basically, it is a FPGA system combined with a RISC type microprocessor. This is a robust combination that allows users to pick and choose any functional peripheral devices only as needed. Once the complete hardware platform is decided upon, the circuit is configured and down loaded to a chip. Software codes are then written to run the application. The hardware system is reconfigurable. Designers can always go back to change the hardware with ease in order to improve the performance and to meet the target cost. This is an attempt to utilize the embedded system design also called System on Programmable Chip (SOPC) to perform Space Vector Modulation (SVM) gate switching strategy. The Altera Nios II IDE tool is selected for this task.

Background: In order to better realize the real-time on-line monitoring of the working state of the coal mill and intellectualize the status of the equipment of the coal mill, the intelligent embedded system of the coal mill based on DSP is studied. Methods: Firstly, the working requirement of coal mill and the task of data acquisition system are briefly introduced, and the requirement of overall embedded system design is put forward. Then, the structure design is carried out from hardware and software, and the embedded system design including digital signal processing, and data acquisition is completed. All patents related to intelligent embedded data acquisition and storage system have been detailed exhaustively. Results: After that, the function test of the actual coal mill embedded system is carried out, which proves the practicability and reliability of the designed embedded system for coal mill and based on DSP. Conclusion: The embedded system improves the automation level of coal mill, and is of great significance to the on-line monitoring and research of large-scale machinery and equipment in the future.

The Embedded System

The paper presents the development of a multifunctional flight display system for light-sport aircraft flying. The requirements and design of the system is discussed. It is mainly designed as a backup system for flying rather than a certified flight instrument. An ARM-core embedded system is chosen as the development platform with Linux operation system. The system basically takes advantage of 3-D positioning information from GPS which has been widely used on general aviation aircraft. Its diverse interfaces provide system redundancy with wired or wireless connection to external sensor systems for aircraft attitude, pressure height, and magnetic heading. The proposed flight display system has been developed and running over the embedded system.

The Embedded System

In this paper, we present our recent effort on using feature technology and ontology for embedded systems modeling and design. We present an overview of embedded system design and propose an object-oriented UML modeling approach to representing embedded systems, i.e., open embedded system model (OESM). OESM supports models of embedded system artifacts, components, features, configuration/assembly, and embedded system platform and family, design rationale, etc. Our focus is on modeling of feature semantic in embedded systems. We call this open embedded system feature model (OESFM). We also present a semantic web environment for modeling and verifying feature models using ontologies, in which the Prote´ge´-OWL is used to precisely capture the relationships among features in feature diagrams and configurations. The OESFM models and ontologies provide a feature-based component collaborative framework. This allows the designer to develop a virtual embedded system prototype through assembling virtual components in which the platform-based HW/SW co-design is supported and the design rationale is captured. The collaborative co-design framework can not only provide formal precise models of the embedded system prototypes but also offers design variation of prototypes whose members are derived by changing certain virtual components with different features.
