It addition, FPGA (Field-ProgrammableGateArray), i.e. field programmable gate array, he is the product of development further on the basis of the programming devices such as PAL, GAL, CPLD.He is to occur as a kind of semi-custom circuit in special IC (ASIC) field, has both solved the deficiency of custom circuit, has overcome again the shortcoming that original programming device gate circuit number is limited.
The circuit design completed with hardware description language (Verilog or VHDL), can quickly be burned onto on FPGA test through simple comprehensive and layout, be the technology main flow of modern IC designs checking.These can edit element can be used to realize the combination function such as decoder or mathematical equation of some basic logic gates (such as AND, OR, XOR, NOT) or more more complicated.Inside most FPGA, in these editable elements, also comprise memory cell such as trigger (Flip-flop) or other more complete block of memory.System designer can couple together the logical block within FPGA as desired by editable connection, just looks like that a breadboard has been placed in a chip.One dispatch from the factory after finished product FPGA logical block and connect can change according to designer, so FPGA can complete required logic function.
FPGA in general speed than ASIC (special IC) is slow, it is achieved same function is bigger than ASIC circuit area.But they also have a lot of advantages such as can quick finished product, the mistake in correction program and less expensive cost can be modified to.Manufacturer is likely to provide the FPGA of cheap still edit capability difference.Because these chips have poor can edit capability, so exploitations of these designs are to complete on common FPGA, then design is transferred on a chip being similar to ASIC.Another method is with CPLD (ComplexProgrammableLogicDevice, CPLD).The exploitation of FPGA is very different relative to tradition PC, the exploitation of single-chip microcomputer.FPGA, based on concurrent operation, realizes with hardware description language；Operate compared to the order of PC or single-chip microcomputer (either von Neumann structure or Harvard structure) and have the biggest difference.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment.CPLD and FPGA includes the Programmadle logic unit of some relatively large amount.The density of CPLD gate is between thousand of to several ten thousand logical blocks, and FPGA is typically several ten thousand to millions of.The main distinction of CPLD and FPGA is their system structure.CPLD is a somewhat restrictive structure.The depositor that this structure is arranged the locking with some relatively small amounts by the logical groups of one or more editable result sum forms.Such result be a lack of edit motility, but but have it is anticipated that time delay and logical block to connect unit height ratio advantage.And FPGA is to have a lot of connection unit, although so allowing him edit more flexibly, but structure is complicated many.
