Npaj-txheej txheem ntawm lub rooj vag uas muaj tiav ntxov

Mar 11, 2019

Txoj kev lag luam FPGA tau tshwm sim los ntawm kev nyeem cov cim nkaus xwb (PROM) thiab cov twj siv tau logic (PLDs). PROMs thiab PLDs ob leeg muaj qhov kev xaiv ntawm kev ua programmed hauv cov khoom rau hauv ib lub hoobkas lossis hauv lub tshav pob (field-programmable). Txawm li cas los xij, qhov kev tsim tau logic tau nyuaj ntawm cov rooj vag cov ntsiab lus.


Altera tau tsim nyob rau xyoo 1983 thiab tau muab cov kev lag luam ua thawj zaug rau kev siv logic hauv xyoo 1984 - EP300 - uas yog qhov chaw quartz nyob rau hauv lub hnab uas tso cai rau cov neeg siv ci ntsa ultra-violet rau cov tuag mus lwv EPROM hlwb uas tuav lub cuab yeej . [8] Thaum lub Kaum Ob Hlis Ntuj xyoo 2015, Intel tau txais Altera.


Xilinx co-founders Ross Freeman thiab Bernard Vonderschmitt invented thawj muag vaj tse-programmable rooj array hauv 1985 - XC2064. [9] Lub XC2064 tau qhov rooj teeb liab thiab cov kev pabcuam hauv nruab nrab ntawm cov rooj vag, pib ntawm lub tshuab tshiab thiab kev ua lag luam. Cov XC2064 muaj 64 teeb meem logic blocks (CLBs), nrog ob lub tswv yim ntawm cov ntxhuav (LUTs). Ntau tshaj li 20 xyoo tom qab, Freeman tau nkag mus rau hauv National Inventors Hall of Fame rau nws tsim muaj.


Nyob rau xyoo 1987, Lub Tsev Nceeg Chaw Nce Cov Chaw Ua Haujlwm tau siv nyiaj los ntawm Steve Casselman los tsim lub koos pij tawj uas yuav siv 600,000 qhov rooj rau lub qhov rooj loj. Casselman tau muaj kev vam meej thiab muaj feem cuam tshuam nrog ib qho patent uas tau tsim tawm rau xyoo 1992.


Altera thiab Xilinx tseem ua tsis tau ntxiv thiab pib sai dua los ntawm 1985 mus rau mid-1990s, thaum competitors sprouted, eroding tseem ceeb kev ua lag luam. Thaum xyoo 1993, Actel (tam sim no Microsemi) ua haujlwm rau 18 feem pua ntawm kev ua lag luam. [10] Los ntawm 2013, Altera (31 feem pua), Actel (10 feem pua) thiab Xilinx (36 feem pua) ua ke sawv cev kwv yees li ntawm 77 feem pua ntawm FPGA kev ua lag luam.


Lub sijhawm xyoo 1990 yog lub sijhawm ntawm kev loj hlob sai sai rau FPGA, ob leeg hauv circuit sophistication thiab qhov ntim ntawm ntau lawm. Nyob rau thaum ntxov xyoo 1990, FPGAs feem ntau siv hauv kev sib txuas lus thiab kev sib tham. Dhau qhov kawg ntawm lub xyoo, FPGAs pom lawv txoj kev mus rau hauv neeg siv khoom, tsheb, thiab kev siv ntawv.
