Use FPGA to realize video and design of video processing application

From;  Author:Stand originally

The field that another is developing quickly is video intelligence. Camera can have moved film, tilt film, but scorch films and panoramic film, but these functions will replace manual interpose by systematic intelligence completely henceforth. Motion detects the video frame that the function stores those exceed athletic door to be restricted only, realize hard disk can more efficiently to store thereby. Video object identifies a function to will need to use monitor automatically, its efficiency should be gotten higher than be being monitored artificially much.

Rise and compress algorithmic progress as resolution, raised taller requirement to systematic performance and framework flexibility, with implementing a system update quickly. As the addition of technical maturity and crop, cost needs to get be reducinged further.

Optional system framework includes standard unit ASIC, ASSP and all sorts of but process designing solution, if digital signal is handled (DSP) or media processor and FPGA. Every kinds of framework has respective actor drawback, final choice depends on the usability of terminal unit requirement and solution. The development tendency that discusses above the basis, ideal framework should have the following characteristic: Cost of sex of class of high-powered, flexibility, Yi Sheng, low development and mature as application and crop increases to the ability with lower migratory cost.

The advantage of FPGA plan

Reduce a demand not only high-powered, pretreatment and aftertreatment function also ask high-powered. In fact, the performance that below a lot of circumstances these functional place require compresses algorithmic itself more than. The example of these functions includes to shrink put adjust, go wave of crisscross, filter and colour space changeover.

What afore-mentioned city places need is high-powered be the framework implementation that cannot use alone processor. The individual parts of an apparatus in this kind of framework cannot satisfy function requirement. Newest job also cannot finish H.264 HD decipher alone at the DSP of 1GHz, and what H.264 HD codes is complex degree compare decipher tower above even 10 times the left and right sides. FPGA is exclusive can solve this problem but process designing solution. Below certain circumstance, the combination of FPGA and exterior DSP processor may be first-rate solution.

As rapid development of the technology, framework must more agile and more upgrade easily. This eliminated standard unit ASIC and ASSP. ASSP is the consumption that is aimed at very big batch technically kind the market designs, meet very quickly normally outdated, because be chosen for this pair of great majority application,ASSP should risk very big risk.

And the cost that develops ASIC is very high. If increase the cost of model of attack by surprise and brilliant circle, software, design verification and domain, the development cost of an ASIC of typical 90nm standard unit may be as high as 3, 0 dollar. Have the biggest lot only consume kind of market ability to accept such high development cost.
