Embedded system network equipment
Sunday, December 6th, 2009 at 06:12 | No commentsCategories: Embedded systemShort Content: In network important today, more and more embedded products had the networking request day by day. In the above embedded product's classification, emphasizes the network function specially besides the network equipment, several other kind of products also have the network request frequently. When talks about the network function, very natural will think of the present application more and more broad Linuxz operating system. Linux has the very strong support ability to the network, even is better than the ... -
In distributional system interior ethernet’s address dynamic disposition
Tuesday, October 28th, 2008 at 12:03 | No commentsCategories: Communication NetworksShort Content: Abstract: The distributional structure is widely applied in the core router and so on the large-scale system, the ethernet is in the distributional system between each subsystem the information transmission good platform. This article unifies the project practice, proposes in the distributional system interior ethernet the MAC address and the IP address one new dynamic collocation method. Proved through the practice that this method has the disposition nimbly, the nurse resources to buckle characteristics and so on easy large scale ... -
Based on PXA255 and embedded QT IP video frequency telephone design
Tuesday, October 21st, 2008 at 17:45 | No commentsCategories: Communication NetworksShort Content: The traditional IP telephone is transforms the voice signal the digital signal, carries on the pack and the compression, on-line carries on the transmission in the data. But in recent years, the people already did not satisfy can only hear the pronunciation, but also hoped that can see opposite party image. This system aims at people's this demand, uses QT/Embedded in the Intel PXA255 platform the graph development kit design a IP video frequency telephone system. 1 hardware system ... -
NexTone: Realizes the conversation management for the IP network
Friday, October 17th, 2008 at 20:00 | No commentsCategories: Communication NetworksTags: IPShort Content: Along with the service provider through IP the pronunciation (VoIP) transmission more and more telephone calls, they discovered that needs to surmount the network edge as well as to penetrate into the network core conversation management. At the same time, must carry on the control in the edge, with the aim of penetrating the firewall as well as network address translation equipment [NAT], these equipment in data net meaningful, and has the sense of purpose, but actually provides the IP ... -
Uses FPGA IP to realize the DDR read-write control design and the confirmation
Sunday, September 7th, 2008 at 13:02 | No commentsCategories: EDA/PLDShort Content: Abstract: This article uses LatticeXP series FPGA to unify IP to solve the DDR RAM read-write control. And has carried on the actual test above the hardware.Key word: Embedded system; DDR RAM; FPGA; IP; LattcieXP Foreword Along with the high speed processor's unceasing development, the embedded system application's domain is getting more and more widespread, digital signal processing's scale is also getting bigger and bigger, in the system the RAM scale increases unceasingly, for instance domains and so on video frequency monitoring, ... -
Uses FPGA and IP Core realizes has custom-made the cushion management
Sunday, August 24th, 2008 at 18:56 | No commentsCategories: EDA/PLDShort Content: In the communication network system, the current capacity management's core is the buffer management, the queue management and the scheduler program. This article unifies uses FPGA and IP Core elaborates the buffer management structure, the principle of work and the design method. At present the hardware high speed repeater technology's tendency is divides into the entire repeater two parts: PE (Protocol Engine, agreement engine) and TM (Traffic Management, current capacity management). And PE completes the protocol processing, TM ...
