In addition, FPGA (Field-ProgrammableGateArray), i.e. field programmable gateArray, he is the product further developing on the basis of the programming devices such as PAL, GAL, CPLDThing, occurs as a kind of semi-custom circuit in special IC (ASIC) field, heSolve the deficiency of custom circuit, also overcome the limited shortcoming of original programming device gate circuit number.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment. CPLD and FPGAComprise the Programmadle logic unit of some relatively large number amounts. The density of CPLD gate arrives several thousandBetween several ten thousand logical blocks, and FPGA normally several ten thousand to millions of. CPLD and FPGAThe main distinction be their system architecture. CPLD is a somewhat restrictive structure. This knotStructure is by the logical groups row of one or more editable result sum and the locking of some relatively small amountsRegister composition. Such result is to lack editor's flexibility, but but has the delay that can estimateTime and the logical block advantage to linkage unit height ratio. And FPGA has a lot of connection listsUnit, although allow like this him edit more flexibly, structure is complicated many. CPLD andThe difference of FPGA another one is that most FPGA contains high-level built-in module (such as additionDevice and multiplier) and built-in memory body. Therefore a relevant important difference is a lot of new FPGASupport to reconfigure completely or in the system of part. The design that allows them along with system upgrade orPerson dynamically reconfigures and changes. Some FPGA can allow a part for equipment update and otherPart continues normal operation.
FPGA has adopted the such concept of logical cell array LCA (LogicCellArray),Inside comprises configurable logic blocks CLB (ConfigurableLogicBlock), input and output mouldPiece IOB (InputOutputBlock) and three parts of interconnector (Interconnect).
Field programmable gate array (FPGA) is programming device, with traditional logic circuit and gate arrayRow (as PAL, GAL and CPLD device) are compared, and FPGA has different structures. FPGAUtilize small-sized look-up table (16 × 1RAM) to realize combinational logic, each look-up table is connected to oneThe input of d type flip flop, trigger drives other logic circuits again or drives I/O, forms thusNot only can realize combination logic function but also can realize the basic logic unit module of sequential logic function, thisA little intermodules utilize metal connecting line to be connected to each other or are connected to I/O module.
