In addition, FPGA (Field-Programmable Gate Array), i.e. field programmable gate array, he is the product further developed on the basis of the programming devices such as PAL, GAL, CPLD, occur as a kind of semi-custom circuit in special IC (ASIC) field, he solves the deficiency of custom circuit, also overcomes the shortcoming that original programming device gate circuit number is limited.
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 logic gate is between several thousand to several ten thousand logical blocks, and FPGA normally arrives millions of several ten thousand.The key distinction of CPLD and FPGA is their system architecture.CPLD is a somewhat restrictive structure.This structure is arranged by the logical groups of one or more editable result sum and forms with the register of the locking of some relatively small amounts.Such result lacks editor's dirigibility, but but have the time delay and logical block that can estimate to the advantage of linkage unit height ratio.And FPGA has a lot of linkage units, although allow him edit more flexibly like this, structure is complicated many.The difference of CPLD and FPGA another one is that most FPGA contains high-level built-in module (such as totalizer and multiplier) and built-in memory body.Therefore relevant important difference be much new FPGA support completely or part system in reconfigure.Allow their design along with system upgrade or dynamically reconfigure and change.Some FPGA can allow a part for equipment update and other parts continue normal operation.
FPGA have employed logical cell array LCA (Logic Cell Array) such concept, and inside comprises configurable logic blocks CLB (Configurable Logic Block), input/output module IOB (Input Output Block) and interconnector (Interconnect) three parts.
Field programmable gate array (FPGA) is programming device, and as compared to conventional logic circuit and gate array (as PAL, GAL and CPLD device), FPGA has different structures.FPGA utilizes small-sized look-up table (16 × 1RAM) to realize combinational logic, each look-up table is connected to the input end of a d type flip flop, trigger drives other logical circuits again or drives I/O, thus constitute the basic logic unit module that not only can realize combination logic function but also can realize sequential logic function, these intermodules utilize metal connecting line to be connected to each other or are connected to I/O module.
