Incazelo

Ukucushwa okuthembekile kokusebenza okuphezulu kwe-bitstream isitoreji nesisombululo sokulethwa kubalulekile kuma-FPGA aminyana kakhulu.I-Platform Flash XL iyidivayisi esebenza kahle kakhulu embonini yokuhlela nokugcina futhi ilungiselelwe ngokukhethekile ukucushwa kwe-FPGA esebenza kahle kakhulu.I-Platform Flash XL ihlanganisa u-128 Mb wesitoreji se-flash ehlelekayo esingaphakathi nohlelo nezici zokusebenza ukuze zicushwe ngaphakathi kwephakheji ye-FT64 yezinyawo ezincane (Umfanekiso 5).Imodi yokufunda ngokuqhuma kwamandla kanye nokunikezwa kwamandla okuzinikele kwe-I/O kunika amandla i-Platform Flash XL ukuthi ihlangane ngaphandle komthungo nesixhumi esibonakalayo somdabu sokucushwa kwe-SelectMAP.Ibhasi ledatha elibanzi, elingu-16-bit liletha i-FPGA yokucushwa kwe-bitstream ngesivinini esingafika ku-800 Mb/s ngaphandle kwezimo zokulinda.Bona i-UG438, Ukucushwa Kwe-Platform Flash XL kanye Nomhlahlandlela Womsebenzisi Wedivayisi Yesitoreji, ukuze uthole ukusetshenziswa kwezinga lesistimu nokucatshangelwa kokusebenza.I-Platform Flash XL isekelwa ukusetshenziswa ne-Virtex-5 noma i-Virtex-6 FPGAs kuphela.Ukusetshenziswa nemindeni emidala ye-Virtex, imindeni ye-Spartan®, noma ama-bitstreams abethelwe e-AES akusekelwa.I-Platform Flash XL iyisisombululo esingaguquguquki sesitoreji se-flash, esilungiselelwe ukucushwa kwe-FPGA.Idivayisi ihlinzeka ngesignali ye-READY_WAIT evumelanisa ukuqala kwenqubo yokumisa ye-FPGA, ithuthukise kokubili ukwethembeka kwesistimu nokwenza lula ukuklama kwebhodi.I-Platform Flash XL ingadawuniloda i-bitstream ye-XC5VLX330 (amabhithi angu-79,704,832) ngaphansi kuka-100 ms, okwenza ukusebenza kokucushwa kwe-Platform Flash XL kusebenze kahle kumaphoyinti okugcina e-PCI Express nezinye izinhlelo zokusebenza ezisebenza kahle kakhulu.I-Platform Flash XL iyisixazululo sokucushwa kwe-single-chip esinamandla engeziwe ezinga lesistimu.Ukusebenzelana okujwayelekile kwe-NOR flash (Umfanekiso 2) kanye nosekelo lwemibuzo ehambisana ne-flash interface (CFI) kunikeza ukufinyelela okujwayelekile komkhakha kusikhala sememori yedivayisi.Umthamo we-Platform Flash XL ongu-128 Mb ungabamba i-bitstreams eyodwa noma ngaphezulu ye-FPGA.Noma yisiphi isikhala sememori esingasetshenziselwa ukugcinwa kwe-bitstream singasetshenziselwa ukubamba idatha yenjongo evamile noma ikhodi eshumekiwe yokucubungula.
