DSP and the Flash connection technology realizes - en.51rd.net
Friday, October 9th, 2009 at 23:37 | No commentsCategories: DSPShort Content: 1 introduction In the modern digital signal processing system, uses Flash to do is the DSP program load and the guidance is one commonly used method, it possibly needed to change the data or the code system maintenance for the user to these future has provided the effective measure. Using the Flash component, can realize the online programming, reduces trouble which the EPROM procedure fever writes brings. 2 Flash AM29LV800B synopsis The Flash memory the name dodges saves, it unified ... -
And realizes - en.51rd.net based on the TMS320DM642 network camera’s design
Friday, October 9th, 2009 at 14:44 | No commentsCategories: DSPShort Content: Along with the networking and multimedia technologies' widespread applications, the digital network video frequency obtained the swift development. In network video frequency conference and in network monitor and control domain, traditional simulated video signal conversion digital video signal, and with the aid of carries on the transmission in the existing IP network to become a now big hot spot. Realizes the way from the technology saying that usually is uses the network camera to realize. At present in the market network ... -
Controls many piece of AD9852 based on TMS320C6701 interface circuit’s design
Friday, October 9th, 2009 at 05:51 | No commentsCategories: DSPShort Content: Because direct digit frequency synthesizer (DDS) has the frequency switching time to be short, the frequency resolution is high, the output phase continuously, the programmable control and the entire digitized structure, are advantageous for the integration and so on high performance, in electronic systems and so on radar, correspondence, electronic countermeasure applies is getting more and more widespread. At present, in the phased-array radar and the multi-channel waveform generator and so on some application situation, starts to appear simultaneously uses ... -
The multimedia gateway system center form drafts a telegram the words sound card the design
Thursday, October 8th, 2009 at 20:57 | No commentsCategories: DSPShort Content: At present, hot spot CTI (computer telephone integration) applies has the media gateway, the IP telephone, the IP facsimile and so on. Sometimes the soft exchange is called calls the server or the media gateway controller. The soft exchange's basic concept is (media gateway) separates the call control function from the transmission level. Realizes the basic call control function through server's on software, like call routing, supervisory control, signaling intercommunication. Because controls the call and calls transmits separates, for the ... -
With realizes - en.51rd.net based on the DSP surfer plan’s software and hardware design
Thursday, October 8th, 2009 at 12:04 | No commentsCategories: DSPShort Content: Along with the modern networking's development, system docking and so on embedded system like monolithic integrated circuit, DSP enter the network the demand to increase day by day, for example has long-distance copies is overly proud can the electric instrument system, to be possible to carry on the remote control the information electrical appliances system and so on. This article uses TI Corporation's TMS320VC33 the DSP chip design and Realtek Corporation's RTL8019 network card's hardware interface electric circuit, and realizes ... -
Based on TMS320C6000 series DSP Viterbi translation program optimization design
Thursday, October 8th, 2009 at 03:11 | No commentsCategories: DSPShort Content: Because the convolution code its encoder is simple, the coding gain high as well as has the very strong correction random error ability, obtained the widespread application in the communications system. Based on biggest likelihood criterion's Viterbi algorithm (VA) is in additive under the white gaussian noise (AWGN) channel the performance best convolution code decoding algorithm, is also commonly used one algorithm [1~2]. Generally speaking, realizes decides Viterbi to decode softly may have three kind of plans to ... -
Based on DSP μC/OS-ⅡExcitation system’s research
Wednesday, October 7th, 2009 at 18:18 | No commentsCategories: DSPShort Content: Synchronous motor's magnetic field uses the direct-current excitation, the power factor may in advance, the lag or the specific power factor, in the movement may to the electrical network present reactive power, improves the electrical network power factor, and has the movement stability to be good, the rotational speed does not change and the operating efficiency higher characteristic along with the variation of load, therefore in industry field applications and so on coal mine is widespread. But the synchronous motor ... -
Lengthens the battery service life using the dual processor
Wednesday, October 7th, 2009 at 09:24 | No commentsCategories: DSPShort Content: Turns toward a lower power loss, the high performance battery to supply the electrical form system development the tendency to be without a doubt. Speaking of the battery supply, the consumer hoped that the portable electronic products can by "the lower electric quantity execution multi-purpose", simultaneously, the numerous manufactured products also start to transfer use the battery power supply. Digital signal processor (DSP) commonly used in request high performance application domain, thus causes the clock running rate to promote unceasingly. ... -
Decoder realizes - en.51rd.net highly effective based on DSP processor’s UMTS Turbo the MAP
Wednesday, October 7th, 2009 at 00:31 | No commentsCategories: DSPShort Content: The Turbo code has been published since 1993, by its splendid performance, has aroused the widespread interest in the industry and the scientific research domain. The Turbo code performance approaches (signal-to-noise ratio difference is 0.7dB or smaller) by Claude E. the Shannon definite channel allowance. Berrou, Glavieux and Thitimajshima proposed the first Turbo code, its structure is composed of two parallel cascade convolution encoder. The Turbo code code scheme produces identical information sequence two to interweave differently the form component ... -
Double CMOS image sensor’s anti-halation image gathering system design
Tuesday, October 6th, 2009 at 15:37 | No commentsCategories: DSPShort Content: 1 introduction The vehicle passes in traffic when the night driving, the opposite automobile headlight's glare will have the visual blind spot to the pilot, will thus cause the serious traffic accident. To eliminate this kind thoroughly, because the automobile halation produces the transportation hidden danger, this article proposed that one kind relieves the night driving based on DSP and the imagery processing technology's anti-halation image gathering system solution to dazzle. At present gains the image mainly to use CCD ...
