In addition, FPGA (Field-ProgrammableGateArray), i.e. field-programmable gate array, he is the product further developed on the basis of the programming devices such as PAL, GAL, CPLD. He occurs as a kind of semi-custom circuit in application specific integrated circuit (ASIC) field, has both solved the deficiency of customization circuit, has overcome again the shortcoming that original programming device gating circuit number is limited.
The circuit layout completed with hardware description language (Verilog or VHDL), it is possible to through simple comprehensive and layout, be burned onto fast on FPGA and test, be the technology main flow of modern IC designs checking. These can edit the combination function such as demoder or mathematical equation that element can be used to realize some basic logic gates (such as AND, OR, XOR, NOT) or more more complex. Inside the FPGA of great majority, in these elements that can edit, also comprise memory cell such as triggering device (Flip-flop) or other more complete block of memory. System design teacher can be connected the logic block of FPGA inside by the connection that can edit as required, just looks like that a breadboard has been placed in a chip. One dispatch from the factory after finished product FPGA logic block and connect can change according to planner, so FPGA can complete required logic function.
FPGA is in general slow than the speed of ASIC (application specific integrated circuit), it is achieved same function ratio ASIC circuit area wants big. But they also have a lot of advantages such as can finished product fast, it is possible to the mistake being modified in correction program and more cheap cost.Manufacturer also may provide the FPGA of cheap still edit capability difference. Because these chips have poor can edit capability, so exploitations of these designs complete on common FPGA, then design is transferred to one and is similar on the chip of ASIC. Another method is with CPLD (ComplexProgrammableLogicDevice, complicated programmable logic device part). The exploitation of FPGA has a great difference relative to the exploitation of conventional P C, micro-chip. FPGA, based on concurrent operation, realizes with hardware description language; Very big difference is had compared to the sequential operation of PC or micro-chip (no matter being Feng's neumann architecture or Harvard's structure).
As far back as mid-term in the 1980's, FPGA takes root in PLD equipment. CPLD and FPGA includes the Programmadle logic unit of some relatively large amount. The density of CPLD logical gate is between several thousand to several ten thousand logical blocks, and FPGA is normally several ten thousand to several hundred ten thousand. The key distinction of CPLD and FPGA is their system architecture. CPLD is a somewhat restrictive structure. The register of the logical groups row of the result sum that this structure can be edited by one or more and the locking of some relatively small amounts forms. Such result lacks editor's handiness, but but has the time of lag that can estimate and logical block to the advantage of connector element height ratio. And FPGA has a lot of connector elements, although allowing him edit more flexibly like this, but structure is complicated many.
Adopt the video file retrieval system based on network communication of the present invention, for cannot according to the technical problem of the automatic downloading and playing video file of the current mood of automobile driver and voice in prior art, speech recognition, pattern recognition and Internet communication technology is adopted to realize officer's speech analysis, mood detection and video file download function respectively, and can automatically play the video file of download, it is the vision enjoyment that automobile driver is provided convenience, enriched.
Although it should be appreciated that the present invention with better embodiment disclose as above, but above-described embodiment and be not used to limit the present invention. For any those of ordinary skill in the art, do not departing from technical solution of the present invention scope situation, all can utilize the technology contents of above-mentioned announcement that technical solution of the present invention is made many possible variations and modification, or be revised as the equivalent embodiment of equivalent variations. Therefore, every content not departing from technical solution of the present invention, the technical spirit of foundation the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
