One kind of system chip function testing method
Friday, September 11th, 2009 at 15:04 | No commentsCategories: DSPShort Content: 1 introduction A correct circuit design attains the factory to make, impossible 100% makes correctly. The general meeting comes under all sorts of uncertainty influence, for instance makes machine's deviation, the environment disturbance, silicon chip's quality even is not identically some artificial fault and so on aspect the influences, produces the product not is complete. If the chip existence has the breakdown, such chip does not allow to flow in absolutely the market. How then to examine has the ... -
Multi-channel UART which realize based on ADSP-BF533 and EPM7160 interface circuit design
Friday, September 4th, 2009 at 07:50 | No commentsCategories: DSPShort Content: 0 introductions At present, in the digital signal processing technology, DSP CPLD is in the control interface design the quite commonly used way. Although however, AD-SP-BF533 has the asynchronous serial port, but this chip only then an asynchronous serial port, when in a system presents many UART connections, ADSP-BF533 appeared is helpless. Therefore, this article uses CPLD to realize the multi-channel UART connection design, satisfies ADSP-BF533 and the multi-channel UART connection correspondence. 1 ADSP-BF533 synopsis The ADSP-BF533 processor is in ... -
Realizes - en.51rd.net based on the ADSP-BF561 H.264 video frequency encoder
Thursday, September 3rd, 2009 at 22:57 | No commentsCategories: DSPShort Content: 0 introductions H.264/AVC is ITU-T VCEG and ISO/IEC the MPEG union formulation newest video frequency code international standard, is one of present visual communication research area hot spot technologies. H.264 video frequency code level (VCL) has used many new technologies, thus enabled its code performance to have the large scale enhancement. But this is increases doubled and re-doubled take the order of complexity as the price, this also causes H.264 is facing the huge challenge in the real-time video frequency ... -
MIMO-OFDMA wireless base depot DSP-FPGA system division
Monday, August 31st, 2009 at 06:03 | No commentsCategories: DSPShort Content: IntroductionThe wireless operator through provides the enhancement digital data service to enhance unit user average return (ARPU), this simultaneously impelled to the wide band demand, causes to be getting higher and higher to the data rate request. Moreover, provides each kind for the user also to urge the first floor network architecture using the experience request to carry on the transformation. Narrow band 2G GSM, the IS-95 system and so on already developed take the pronunciation as the central technology ... -
32 DSP two level of cache structural designs
Sunday, August 30th, 2009 at 03:23 | No commentsCategories: DSPShort Content: Abstract: Used flow from the top to design section of 32 DSP cache. This cache uses two levels of structures, the first level uses the Harvard structure, the second level uses the Princeton structure. This article elaborated the algorithm which in detail this cache structural design and uses. Key word: cache, DSP, memory system. 1 introduction Along with Semiconductor Technology's development, the DSP performance enhances unceasingly, is widely applied in the control, the correspondence, domains and so on ... -
DSP in parallel double round electric car control system’s application
Friday, July 10th, 2009 at 17:48 | No commentsCategories: DSPShort Content: 1 introduction in 2001, American inventor Kamen has invented one kind of new convenience quick two round transportation vehicle "Segway", walks the balancing control technology to become the global robot control technology the research hot spot. Moved the platform take the parallel double round electric car achievement to provide the technical support as robot's research, because simultaneously his behavior and the rocket flight and two full robots had the very big similarity, thus had the significant theory and the ... -
Based on DSP frequency modulation modulator design
Friday, July 10th, 2009 at 00:02 | No commentsCategories: DSPShort Content: The software radio the basic philosophy is take open, expandable, the structure most Jan's hardware as the general platform, with may promote the multi-correspondence function, may replace the software realize as far as possible. Its central thought is: Constructs one to have standardized, the modular general hardware platform, and loads through the software realizes each kind of wireless communication function one kind of open style architecture. This article based on this thought that first constructs DSP and the PC machine ... -
DSP system’s modelling and disposition
Friday, July 3rd, 2009 at 08:02 | No commentsCategories: DSPShort Content: The embedded software development needs has the widespread thorough understanding and the understanding to the goal construction and the use. Transforms the embedded system from the concept for can effectively the highly effective solution which deployed in the hardware environment, needs a series of steps. The entire process includes: Analysis, construction build, appraisal, hardware support, design, code, debugging, integration, confirmation and confirmation. In this process, if the hardware source has not obtained the effective use, perhaps the software has ... -
Embedded object module in DSP in system development application
Wednesday, July 1st, 2009 at 02:42 | No commentsCategories: DSPShort Content: IntroductionAlong with electronic technology unceasing progress, specially 3C (computer, correspondence, expense electron) the swift development, the electronic installation day by day digitization, the miniaturization and the integration, the embedded chip becomes the design development personnel's first choice gradually. DSP takes the embedded chip the model to represent one, obtained the widespread application in the information industries domain.Although DSP was the 3C product development provides the very good hardware to support the platform, but the designer still expenditure certain time grasped ... -
Based on embedded DSP class media codec encoder-decoder - 51rd Chinese electronic net
Monday, June 29th, 2009 at 15:08 | No commentsCategories: DSPShort Content: Programmable DSP may use in realizing each kind of existing codec encoder-decoder and the future arranges the decoding standard. The present tendency will be issues every two years new will arrange the decoding standard, each new standard will meet the need more DSP cycles. Therefore, the choice has the compatible development blueprint DSP platform (for example ZSP) to be important, like this through system upgrade, but the redesign then satisfies future system request. Multimedia will designate all elements (including ...
