ALTERA DDR2 SDRAM Controller

Ulwazi Olubalulekile

Izilawuli ze-Altera® DDR, DDR2, kanye ne-DDR3 SDRAM ezine-ALTMEMPHY IP zinikeza ukuxhumana okulula ku-DDR, DDR2, ne-DDR3 SDRAM esezingeni lomkhakha. I-ALTMEMPHY megafunction iwukuxhumana phakathi kwesilawuli sememori namadivayisi enkumbulo, futhi yenza imisebenzi yokufunda nokubhala kumemori. Izilawuli ze-DDR, DDR2, kanye ne-DDR3 SDRAM ezine-ALTMEMPHY IP zisebenza ngokuhlanganyela ne-Altera ALTMEMPHY megafunction.
Izilawuli ze-DDR ne-DDR2 SDRAM ezine-ALTMEMPHY IP kanye ne-ALTMEMPHY megafunction zinikeza ukuxhumana kwe-DDR ne-DDR2 SDRAM okunesilinganiso esigcwele noma uhhafu.Isilawuli se-DDR3 SDRAM esine-ALTMEMPHY IP kanye ne-ALTMEMPHY isekela i-megafunction ye-DDR3 SDRAM ukuxhumana kumodi yezinga eliphakathi. Izilawuli ze-DDR, DDR2, kanye ne-DDR3 SDRAM ezine-ALTMEMPHY IP zinikeza isilawuli esisebenza kahle kakhulu II (HPC II), esinikeza ukusebenza kahle okuphezulu nezici ezithuthukile. Umfanekiso 15–1 ukhombisa umdwebo wezinga lesistimu ohlanganisa nowangaphambiliampizinga eliphezulu file ukuthi i-DDR, DDR2, noma i-DDR3 SDRAM Controller ene-ALTMEMPHY IP ikudalela yona.

Umfanekiso 15-1. Umdwebo Wezinga Lesistimu

Qaphela kuMfanekiso 15–1:
(1) Uma ukhetha u-Instantiate DLL Ngaphandle, iluphu evaliwe (i-DLL) ifakwa ngaphandle kwe-megafunction ye-ALTMEMPHY.

I-MegaWizard™ Plug-In Manager ikhiqiza i-exampizinga eliphezulu file, ehlanganisa i-example driver, kanye ne-DDR, DDR2, noma i-DDR3 SDRAM yakho yesilawuli esisebenza kahle esishintshashintshayo. Isilawuli sibeka isibonelo se-ALTMEMPHY megafunction ephinde iqinise iluphu evaliwe ngesigaba (PLL) kanye ne-DLL. Ungakwazi futhi ukufakazela i-DLL ngaphandle kwe-ALTMEMPHY megafunction ukuze wabelane nge-DLL phakathi kwezimo eziningi ze-ALTMEMPHY megafunction. Awukwazi ukwabelana nge-PLL phakathi kwezimo eziningi ze-ALTMEMPHY megafunction, kodwa ungase wabelane ngokuphumayo kwewashi le-PLL phakathi kwalezi zimo eziningi.

Ukuze usebenzise i-DDR3 SDRAM HPC, ungacela ilayisensi file kusuka e-Altera web indawo ku www.altera.com/licensing futhi uyifake kukhompyutha yakho. Uma ucela ilayisense file, i-Altera ikuthumelela i-licence.dat file. Uma ungenakho ukufinyelela ku-inthanethi, xhumana nommeleli wendawo yangakini.
Ukuze usebenzise i-DDR3 SDRAM HPC II, xhumana nommeleli wendawo yangakini wezentengiso ukuze u-ode ilayisensi.

Ukuhlola Kwamahhala

Isici sokuhlola se-OpenCore Plus sika-Altera sisebenza kuphela ku-DDR3 SDRAM HPC. Ngesici sokuhlola se-OpenCore Plus, ungenza lezi zenzo ezilandelayo:

• Lingisa ukuziphatha kwe-megafunction (umsebenzi we-Altera MegaCore noma AMPPSM megafunction) ngaphakathi kwesistimu yakho.
• Qinisekisa ukusebenza kwedizayini yakho, futhi uhlole usayizi wayo nesivinini ngokushesha futhi kalula.
• Khiqiza uhlelo lwedivayisi olunesikhathi esinqunyelwe files yemiklamo ehlanganisa imisebenzi ye-MegaCore.
• Hlela idivayisi futhi uqinisekise idizayini yakho kuhadiwe.

Udinga ukuthenga ilayisense ye-megafunction kuphela uma weneliseke ngokuphelele ngokusebenza kwayo nokusebenza, futhi ufuna ukuyisa umklamo wakho ekukhiqizeni.

I-OpenCore Plus Time-out Behavior

Ukuhlolwa kwehadiwe ye-OpenCore Plus kungasekela izindlela ezimbili zokusebenza ezilandelayo:

• Ayixhunyiwe—umklamo usebenza isikhathi esilinganiselwe
• Isebenzisa ifoni njengemodemu—idinga ukuxhumana phakathi kwebhodi lakho nekhompuyutha engusokhaya. Uma imodi yemodemu isekelwa yiwo wonke ama-megafunctions edizayini, idivayisi ingasebenza isikhathi eside noma ingunaphakade.

Wonke ama-megafunctions ekuphelelweni kwesikhathi kwedivayisi ngesikhathi esisodwa lapho isikhathi sokuhlola esikhawulelwe kakhulu sifinyelelwa. Uma kukhona ama-megafunction angaphezu kweyodwa edizayini, ukuziphatha kwesikhathi sokuvala komsebenzi othile we-mega kungase kufihlwe ukuziphatha kokuphuma kwesikhathi kwamanye ama-megafunctions.

Kumisebenzi ye-MegaCore, isikhathi sokuvala esingaxhunywanga yihora elingu-1; inani lokuvala elifakwe njengemodemu alinamkhawulo.

Idizayini yakho iyeka ukusebenza ngemva kokuphelelwa yisikhathi kokuhlolwa kwezingxenyekazi zekhompuyutha kanye nokuphumayo kwendawo_kokulungele ukwehla.
