Ntsaws-qhov txheej txheem ntawm sab nraud tuaj

Mar 11, 2019

Ib qhov kev ua lag luam uas muaj peev xwm tuaj yeem tsim tau (FPGA) yog ib qho kev sib cog ua ke tsim los ntawm tus neeg qhua los yog tus tsim tawm tom qab kev tsim tawm - li no lub sij hawm "field-programmable". FPGA configuration feem ntau tau teev lus siv cov lus piav qhia txog kev kho vajtse (HDL), zoo ib yam li uas siv rau daim ntawv thov kev sib xyuas (ASIC). Circuit diagrams twb tau siv los qhia qhov teeb meem, tab sis qhov no yog nce tsis tshua muaj vim cov kev tsim hluav taws xob tsim cov cuab yeej hluav taws xob.

FPGAs muaj ib qho array ntawm cov khoom siv logic, thiab hierarchy ntawm reconfigurable interconnects uas cia cov blocks kom "wired together", zoo li ntau cov rooj vag cov ntsiab lus uas tuaj yeem inter-wired nyob sib txawv. Logic blocks tau teeb tsa los ua qhov sib txuam ua ke, los yog yooj yim ntawm cov rooj vag log yooj yim xws li THIAB THIAB XOR. Feem ntau ntawm FPGAs, logic blocks tseem muaj xws li cov cim xeeb, uas tej zaum yuav yog qhov yooj yim flip-flops lossis ntau dua cov cim xeeb ntawm kev nco. Ntau FPGAs yuav tsum tau reprogrammed los siv ntau cov logic zog, uas yooj ywm reconfigurable xam ua tau hauv computer software.
