MCU needs to improve - en.51rd.net
Tuesday, May 26th, 2009 at 17:19 | No commentsCategories: SCMShort Content: For long, computer system's antijamming has been the important question which the people cared, because the computer uses more and more broadly, the reliability is getting more and more important, but the antijamming is in itself the reliable important component. For automobile, airplane, satellite, reactor security, the people have spent the massive energy and the money in the antijamming question, although had already made the considerable progress, but far cannot satisfy the request in the performance-to-price ratio, so that the ... -
Space monolithic integrated circuit system antijamming technology
Tuesday, November 25th, 2008 at 12:42 | No commentsCategories: SCMShort Content: Abstract: The monolithic integrated circuit system is often undertaking the very vital task in the space instrument, because the monolithic integrated circuit belongs to the sensitive component to the disturbance, easy to come under the disturbing effect, causes the overall system paralysis, therefore should consider the antijamming question fully in the system design, enhances system's reliability. Reason which produces according to the disturbance, union practice, introduced in the space instrument from the hardware and the software two aspects the monolithic ... -
Serial communication system’s antijamming design
Wednesday, October 29th, 2008 at 05:50 | No commentsCategories: Communication NetworksShort Content: The electrical power system movement's security or not had the close relationship with the system running status then, regarding the electric power dispatch department, if could real-time grasp the electrical power system various part of running status comprehensively, carried on the long-distance monitor, to guarantee system's security, stable, the economical movement had the very vital significance without doubt. The electric power long-distance monitor uses the serial mode to carry on the correspondence generally, guaranteed that the data the reliable ... -
Microcomputer protection control interface installment CPLD antijamming design
Sunday, October 26th, 2008 at 12:17 | No commentsCategories: EDA/PLDShort Content: Abstract: Introduced that one kind designs the microcomputer protective system control interface with VHDL on the CPLD chip the method to enhance the resistance to interference, the test result indicated: Control interface's resistance to interference is very high, realizes the microcomputer protective system's redundant reliable control completely. The connection speed is high, the high integration rate, can direct and the high speed DSP system connection, has the high promoted value.Key word: Microcomputer protection; Antijamming; Redundancy design; VHDL; CPLD Directing Word The microcomputer protective ... -
Based on DSP digital image processing system’s antijamming design
Tuesday, September 23rd, 2008 at 17:56 | No commentsCategories: DSPShort Content: 0. Introduction Along with human culture's progress and electronic technology's fast development, the video communication as human field of vision's extending, is widely applied in the various trades and occupations. Arises at the historic moment the digital image processing technology also obtained has developed rapidly. At present, because the operating speed is quick, on the piece the fruitful in resources and can realize complex reasons and so on linearity and misalignment algorithm, DSP has become domain and so on ... -

Two kinds “software trap technology” comparison
Monday, September 8th, 2008 at 04:22 | No commentsCategories: SCMShort Content: Introduction The monolithic integrated circuit application system's antijamming may divide into the software and the hardware two aspects specifically, the software antijamming by its design nimble, the economical hardware source, reduces superiority and so on cost to obtain the widespread use more and more. The software antijamming technology mainly has "the instruction redundant technique", "the software trap technology", "the software watch-dog technology", "the digital filtering technology" and so on. This article with realizes the method on the software trap ... -
PLC control system’s electromagnetic interference origin and antijamming design
Saturday, September 6th, 2008 at 12:02 | No commentsCategories: EDA/PLDShort Content: Along with the industrial equipment automation control technology's development, programmable controller (PLC) is getting more and more widespread in the industrial equipment control's application. The PLC control system's reliable immediate influence to enterprise's safety in production and the economical movement, system's antijamming ability is relates the overall system reliability service the key. This article introduced in detail affects the PLC movement the disturbance type and the origin, and proposes the antijamming design implementation strategy. The automated system ...
