In addition, FPGA (Field-Programmable Gate Array), i.e. field programmable gate array, he be
The product further developed on the basis of the programming devices such as PAL, GAL, CPLD.He is led as application specific integrated circuit (ASIC)
A kind of semi-custom circuit in domain and occur, both solved the deficiency of custom circuit, overcome original programming device door again
The shortcomings that circuit number is limited.
The circuit design completed with hardware description language (Verilog or VHDL), simple synthesis and cloth can be passed through
Office, is quickly burned onto on FPGA and is tested, and is the technology main flow of modern IC designs checking.These editable elements can be by
For realizing some basic logic gates (such as AND, OR, XOR, NOT) or more more complicated combination function such as
Decoder or mathematical equation.Inside most FPGA, also for example touched comprising memory cell in these editable elements
Send out device (Flip-flop) or other more complete block of memory.System designer can be as desired by editable company
Connect the logical block inside FPGA to connect, just look like that a breadboard has been placed in a chip.One dispatches from the factory
The logical block of finished product FPGA afterwards and connection can change according to designer, so FPGA can complete required logic work(
Energy.FPGA exploitation is very different relative to the exploitation of traditional PC, single-chip microcomputer.FPGA is retouched based on concurrent operation with hardware
Predicate is sayed to realize;Have compared to the operation of the order of PC or single-chip microcomputer (either von Neumann structure or Harvard structure) very big
Difference.
Early in 1980 mid-nineties 90s, FPGA takes root in PLD equipment.CPLD and FPGA includes some relatively large numbers
The Programmadle logic unit of amount.The density of CPLD gates it is thousands of arrive tens of thousands of individual logic units between, and FPGA be typically exist
It is tens of thousands of to millions of.
The CPLD and FPGA main distinction is their system architecture.CPLD is a somewhat restricted structure.This
Structure is made up of the register of the locking of the logical groups row and some relatively small amounts of one or more editable result sum.
Such result be a lack of edit flexibility, but have it is anticipated that time delay and logic unit ratio high to connection unit
The advantages of rate.And FPGA is to have many connection units, although so allowing it more flexibly to edit, structure is but
Complicated is more.
CPLD and FPGA another difference be most FPGA contain high-level built-in module (such as adder and
Multiplier) and built-in memory body.Therefore a relevant important difference is that many new FPGA support complete or part
System in reconfigure.Allow their design as system upgrade or dynamic reconfigure and change.Some FPGA can
To allow a part for equipment to update, other parts continue normal operation.
It is artificial for existing minor's type identification pattern using workshop minor's identification system of the present invention
The technical problem that cost is too high and monitoring precision is relatively low, location technology and wireless communication technology are used to ensure using an identification
System can complete the target monitoring of all monitor areas, while the knowledge of identifying system is improved using IMAQ identification technology
Other accuracy, and in exception and alarm, so as to effectively safeguard the normal operation circumstances of electrician workshop.
