10AX115H2F34E2SG FPGA Arria® 10 GX Mhuri 1150000 Masero 20nm Technology 0.9V 1152-Pini FC-FBGA

CPLD ndiyo chidimbu chezvakaoma programmable logic device,FPGA ​​ndiyo chidimbu chemunda unorongwa gedhi array, basa rezviviri izvi rakafanana, asi musimboti wekuita wakasiyana zvishoma, saka dzimwe nguva tinogona kufuratira musiyano uripo pakati pezviviri izvi, pamwe chete. inonzi programmable logic device kana CPLD/FPGA.Kune makambani akati wandei anogadzira CPLD/ FPGas, makuru matatu ari ALTERA, XILINX, uye LAT-TICE.CPLD decomposition combinatorial logic function yakasimba kwazvo, macro unit inogona kuora gumi nemaviri kana kutopfuura 20-30 combinatorial logic input.Nekudaro, iyo LUT yeFPGA inogona chete kubata iyo yakasanganiswa logic ye4 mapipu, saka CPLD yakakodzera kugadzira yakaoma musanganiswa mantiki senge decoding.Nekudaro, maitiro ekugadzira eFPGA anoona kuti huwandu hweLUTs uye zvinokonzeresa zviri muFPGA chip yakakura kwazvo, kazhinji zviuru zvezviuru, CPLD inogona kungowana 512 inonzwisisika mauniti, uye kana iyo chip mutengo wakakamurwa nenhamba ine musoro. mayunitsi, avhareji inonzwisisika unit mutengo weFPGA yakaderera zvakanyanya pane iyo yeCPLD.Saka kana huwandu hukuru hwezvinokonzeresa huchishandiswa mukugadzira, sekugadzira yakaoma nguva yekufunga, saka kushandisa FPGA isarudzo yakanaka.

Kunyangwe zvese FPGA neCPLD zviri programmable ASIC zvishandiso uye zvine akawanda akajairika maitiro, nekuda kwekusiyana kwechimiro cheCPLD neFPGA, ivo vane hunhu hwavo:

• CPLD inonyanya kukodzera kupedzisa akasiyana algorithms uye combinatorial logic, uye FPGA inonyanya kukodzera kupedzisa sequential logic.Mune mamwe mazwi, FPGA inonyanya kukodzera flip-flop yakapfuma chimiro, nepo CPLD inonyanya kukodzera flip-flop yakaganhurwa uye chigadzirwa term rakapfuma chimiro.
• Iyo inoenderera mberi yekumisikidza chimiro cheCPLD inoona kuti kunonoka kwayo nguva kwakafanana uye kufembera, nepo iyo yakakamurwa nzira yeFPGA inoona kuti kunonoka kwayo hakuna fungidziro.
• FPGA ine kuchinjika kwakawanda kupfuura CPLD mukuronga.
• CPLD inorongedzerwa nekugadzirisa iyo logic basa reyakagadziriswa yemukati wedunhu, nepo FPGA inorongwa nekushandura wiring yemukati yekubatanidza.
• Fpgas inogona kurongwa pasi pemagedhi ane logic, ukuwo CPLDS yakarongwa pasi pemabhuroki anonzwisisika.
• FPGA yakabatanidzwa kupfuura CPLD uye ine yakanyanya kuomarara wiring chimiro uye kuita zvine musoro.

Kazhinji, kushandiswa kwesimba kweCPLD kwakakura kudarika iyo yeFPGA, uye yakakwirira yedhigirii yekubatanidza, inonyanya kuoneka.
