Based on SPCE061A and CPLD electrically operated bicycle charge system development
Saturday, November 29th, 2008 at 04:55 | No commentsCategories: EDA/PLDShort Content: Because the electric car has the non-waste gas pollution, not to have the noise facilely, artistic and so on characteristics, receives the numerous user's favors. But in the use also exposes its limitation, that was accumulator cell's capacity has decided its use scope, moreover had the duration of charging long shortcoming. At present along with the electrically operated bicycle's development, how the urgently needed solution's question to realize the fast nimble charge. Along with the electronic technology, the programmable logical component ... -
Based on CPLD MIDI music player design
Thursday, November 27th, 2008 at 17:55 | No commentsCategories: EDA/PLDShort Content: Abstract: This music player rests on the MIDI music basic principle, unifies the EDA technology, uses the ALTERA Corporation's programmable logical component (CPLD) EPF10LC84-4 to design as the control core.

Wireless in peeps the system design based on ARM7
Tuesday, November 25th, 2008 at 15:25 | No commentsCategories: SCMShort Content: The abstract designs and realizes one kind as well as the blue tooth wireless in peeps the system based on ARM7 chip AT9lR40008. The system uses CPLD to control the CMOS camera gathering real-time image data, carries on the JPEG-LS compression with ARM7, through the blue tooth transmission for the PC on receive software, carries on the decoding demonstration to the image. This system demonstrated a complete digitization miniature wireless to peep the system, was further causes the integrated chip ... -
Based on video frequency decoding chip and CPLD real-time image gathering system
Saturday, November 22nd, 2008 at 08:12 | No commentsCategories: EDA/PLDShort Content: Image gathering is the real-time imagery processing important step. At present, the image sensing component mainly has CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor). The CCD technology already was now mature, the CCD camera was still the high-end application first choice component. It outputs simulated video signal including image signal, line and field blanking wave, line and field synchronizing signal and so on seven kind of signals. The traditional video frequency gathering system by a/D switching ... -
Step-by-steps the electrical machinery controller design based on FPGA
Thursday, November 20th, 2008 at 01:12 | No commentsCategories: EDA/PLDShort Content: Step-by-steps the electrical machinery is one kind transforms the electricity signal impulse the corresponding angular displacement's special electrical machinery, changes a circular telegram condition every time, step-by-steps electrical machinery's rotor to rotate one step. At present majority step-by-steps the electrical machinery controller to need the master-control unit transmission clock signal, and must a I/O mouth come the secondary control and the monitoring at least step-by-steps electrical machinery's operational aspect. In the monolithic integrated circuit or in the DSP application ... -
Isolates the card based on the PCI main line’s network bodyguard the hardware design
Tuesday, November 18th, 2008 at 11:25 | No commentsCategories: Communication NetworksShort Content: Picking Wanting: The article gave one kind to carry on safe visit to the net computer hard disk information the isolation card to realize the plan continually, introduced based on the PCI main line's double hard disk isolation card's composition and the principle of work, discussed its hardware design in detail.Key word: Isolation card; Physical isolation; CH365; CPLD; IDE Introduction Because the network termination equipment's majority of data save on the hard disk, therefore, data security's core is the hard disk ... -
