international conference on Mixed Design of Integrated Circuits and Systems (MIXDES)

作者： Jan Wychowaniak Pawel Predki Dariusz Makowski Andrzej Napieralski Department of Microelectronics and Computer Science Technical University of Lodz Lodz Poland

The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful and efficient platform. With multiple integrated solutions like redundancies and intelligent control mechanisms this technology is characterized with reliability estimated at the level of 99.99999 percent. These features make the standard perfect for use in projects like the free electron laser in Hamburg (FLASH) and the X-ray free electron laser (X-FEL) in order to help them meet the requirements of high availability and reliability. The ATCA standard incorporates advanced control systems defined in the intelligent platform management interface (IPMI) specification as one of the key elements. The entire ATCA implementation retains its functionality as long as the IPMI remains operational. The complexity level of the application increases, which results in preparing it to run and debugging being more difficult to perform. At the same time, only scrupulous elimination of any kind of possible deficiencies can enable the ATCA implementation to offer the desired level of reliability. Thus, diagnostics become crucial, which creates a need for additional tools performing these tasks during the preparations of both hardware and software for the ATCA application. The paper presents application aiding in development of the prototype carrier board by enabling the user of external PC station to perform diagnostic and control activities over the board. It helps in examining all its components at the stage of running the board, as well as in further operation analysis.

international SoC Design conference, ISOCC

作者： Li Li Ken Choi Seongmo Park Moo-Kyoung Chung Department of Electrical and Computer Engineering Illinois Institute of Technology Chicago USA IT Convergence & Components Laboratory SoC Research and Development Group Electronics and Telecommunications Research Institute Daejeon South Korea

ISBN: (纸本)9781424450343;9781424450350

In this paper, we propose a RT level power reduction scheme which can be used for the applications that require ultra-low power consumption. A novel wasting-toggle-rate (WTR) based clock power reduction technique is introduced. It compares the WTR of a stimulus with the pre-computed threshold WTR of the circuit, and clock gating is applied to the circuit only if there is power-saving benefit. It considers not only clock enable signal, but also data signal and wasting toggle rate of the clock in a fine-grained manner. The proposed technique is implemented at RT level in a complete CAD solution. We have tested the proposed technique on real industrial multimedia-mobile-processor design. For the accuracy of the power optimization results, all the power estimation results are measured at gate level after synthesis by using industrial 65 and 90 nanometer technology libraries. The experimental results show that using 65 nanometer technology, the technique reduces 35.46% power comparing with non-clock gating design and 18.80% power comparing with clock-gating design by Power Compiler; and that using 90 nanometer technology, the technique reduces average 39.34% total power comparing with non-clock gating design and 27.76% total power comparing with clock-gating design by Power Compiler. For the design overhead of the proposed technique, it increases 1.17% of the critical path delay and reduces 0.81% of the area for the whole circuit comparing with the original circuit in 65 nanometer technology, and increases 2.75% of the critical path delay and reduces 0.75% area for whole circuit in 90 nanometer technology.

Image matching is an effective auxiliary location method for the precise guide weapon system. The image sensor of image matching system is used to real-time gather the object image around target or that throughout the flight way, which will be compared with the reference data of the upper computer in the missile, to process and locate the correct position of the target relative to the missile. The performance of the image matching system is vitally interrelated to the geographic and conditions (Ground image characteristics) of the operation region. So the basic operation condition of the image matching system and matching region selection in the special geographic conditions is regarded as the main contents to study. Taken the developing demands of an important national defense weapon system as the background, we carry out a series of theory analysis and simulation study base on the actual data, in order to improve the matching accuracy of the down-look image matching system and determine the main factors influencing the operation performance of the image matching system in further. And we build a set of functional relationship relative to the performance and specifications of the image matching system, image statistic parameters and operation conditions. By analyzing and verifying these functions relationship, finally we point out the parameters influencing the image matching system under different environmental conditions, and point out principle thought and method of selecting image matching area according to these parameters. These study results have been used and proved in the product development. And it provides the basis for us to determine the selection regulations of matching area of down-look system, laying a foundation for improving the operation performance of the image matching system in different environmental conditions.
