In recent years, was rapid to the digital video product's demand growth. The digital video product's mainstream application including the video communication, the video frequency monitoring and the industrial automation, most popular is the entertainment application, like DVD, HDTV, satellite TV, sign clear (SD) or high clear (HD) set-top box, digital camera and HD camera, high-end monitor (LCD, plasma monitor, DLP) as well as individual camera and so on. These applications arrange the decoding algorithm and the standard to the ...

       1 introduction        Develops unceasingly along with the DSP technology and consummates, digital signal processing's application scope is getting more and more widespread. The labor controls, the computer, the correspondence and in the expense electronic products, could find its shadow. In recent years, along with the multimedia correspondence's vigorous developments, DSP also more and more applications in the multimedia correspondences, but DSP used in aspects and so on pronunciation compression and imagery processing in the multimedia correspondences, but these needed ...

    1 introduction     Is day by day perfect along with the digital signal processing theory and the ultra large scale integrated circuit technology swift development, under each kind of real-time processing application demand's impetus, digital signal processor (DSP) also obtained more and more widespread application.     The DSP monitoring is in the DSP development and the application the very important link. At present in the DSP performance history, the most commonly used way is through purchases processor's JTAG simulator ...

Abstract integration peripheral device's increase, software application complexity further increase, causes the work load which the development peripheral device driver needs to increase greatly. TI Corporation proposed the kind of/micro actuation model driver structure. The practice result indicated that after using class/the micro actuation model carries on the driver design, the application software may the multiplying major part similar equipment's driver, thus raised the driver development efficiency enormously.Key word DM642 I/O equipment actuation class/micro actuation model DSP/BlOS real-time operating system ...

The abstract adds our type to TMS320C6000 series DSP several kind of start load plan's EMIF to carry on the detailed analysis. Then take TMS320C6713 DSP as the example, proposed that one kind the direct firing writes Flash in the master routine the means that and carries on the comparison with the commonly used FlashBurn tool. The experiment proved that this DSP start load plan easy to realize, is more convenient than reliably the traditional method use.Key word TMS320C6000 starts ...

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 ...

Digest: This article described in detail (Texas Instruments) C55x in the series DSP platform integrated in TI real-time realizes 0.3kbps to arrange the decoding algorithm to the 16kbps many kinds of speed pronunciations the method, and optimized the assembly directive in the existing C language source code foundation the skill. Introduced in compiles C55x in the series DSP assembly program the key technologies, such as in function call's parameter transmission, the instruction optimizes, flag bit establishment, great use and so ...

Speaking of based on the digital signal processor (DSP) system, the optimized power loss is one item important, but often with difficulty realizes project objective. Now, unified frequently based on the DSP equipment formerly respectively the independent many applications, each application possibly has many working patterns. Must obtain this kind of equipment's power distribution is a very difficult matter, idle talk entire complex system. The designers need to learn that as far as possible many best information, as well as ...

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 ...
