FPGA medium-soft FIFO designs and realizes - en.51rd.net
Monday, November 24th, 2008 at 14:55 | No commentsCategories: EDA/PLDShort Content: Abstract: In the modern circuit design, a system has often contained many clocks, how to transmit the data in the asynchronous clock between to become a very important question, but uses asynchronous FIFO to be possible to solve this problem effectively. Asynchronous FIFO was one kind obtains the widespread application component in the electronic system, in the article introduced one kind based on the FPGA asynchronous FIFO design method. Uses this method to be possible to design high speed, high ... -
Based on FPGA parallel DSP chip real-time image coding platform
Saturday, November 22nd, 2008 at 13:12 | No commentsCategories: EDA/PLDShort Content: Introduction The image compression technology is getting more and more important in the modern life's status, along with present's DSP processing data speed's enhancement, speaking of the traditional image compression, monolithic DSP then achieves the very good effect. But as a result of the information content growth, concept and so on high definition statements, system's processing data ability also needs to enhance particularly, when particularly requests the real-time image compression code, monolithic DSP is unable to be competent such ... -
All opens the distributional monitoring unit based on field bus’s hospital hospital ward
Saturday, November 22nd, 2008 at 08:46 | No commentsCategories: Communication NetworksTags: connection, Field bus field busShort Content: 0. Foreword In the early-1980s, along with the sensing examination technology, the simulation and the digital communication technology, the computer applied technology, the microelectronic technology and so on many new technology's rapidly expands, the belt each kind of micro computer's guardianship meter and the monitoring unit then arose at the historic moment. The hospital hospital ward guardianship also gradually changes by the artificial clinical guardianship using the scene guardianship meter and the monitoring unit realizes the long-distance guardianship. Specially ... -
Based on FPGA musical instrument digital interface music FM synthesizer
Tuesday, November 18th, 2008 at 04:12 | No commentsCategories: EDA/PLDShort Content: l introduction The musical instrument digital interface (Musical Instraament Digital Inter face, MIDI) was to solve between the electroacoustical musical instrument's correspondence problem to propose in the early-1980s. The MIDI transmission is not the sound signal, but is instructions and so on note, controlled variable, it instructed that the MIDI equipment must make anything, how to do, which note like plays, the great volume and so on. They are unified express the MIDI news (MIDI Message). When transmission uses the ... -
Based on C8051F020 general serial port adapter’s design
Monday, November 17th, 2008 at 19:52 | No commentsCategories: Communication NetworksShort Content: 1 introduction Serial communication's widespread application may cause each kind of transmission facility organically to be united as one body, can carry on the data exchange and the information transmission reliably safely. But because on each equipment transmission channel's signal is different, applies the serial port are also various, must complete the numerous equipment correspondences, inevitably must involve to each equipment's between serial port transformation question. In order to cause computer's RS-232 connection to carry on the correspondence with each ... -
Based on VerilogHDL background noise deduction circuit design
Monday, November 17th, 2008 at 03:12 | No commentsCategories: EDA/PLDShort Content: Abstract: A design of circuit which can deduct background noise based on VerilogHDL is introduced in this paper. Compared with the circuit used chips of the forward and backward counters, its interface with MCU is more simple and operation of software is more easy. Key Word: VerilogHDL, background noise, deduction 1 introduction In the weak signal detection method, often needs to cause the direct-current quantity after the electro-optical modulation transforms for the exchange signal carries on ...
