• Umzekelo we-synthesis example uyilo. Njengoko kuchaziwe kwicandelo langaphambili, i-synthesis exampuyilo luqulathe umvelisi wendlela kunye nomzekelo wojongano lwenkumbulo. Ezi bloko zingagqibekanga kwiimodeli zokulinganisa ezingabonakaliyo apho kufanelekileyo ukulinganisa okukhawulezayo.
• Imodeli yememori, esebenza njengemodeli eqhelekileyo ebambelela kwiinkcukacha zeprotocol yememori. Rhoqo, abathengisi beememori babonelela ngeemodeli zokulinganisa kumacandelo abo enkumbulo onokuthi ukhuphele kuwo webiindawo.
• Umkhangeli wesimo, obeka iliso kwiimpawu zesimo ukusuka kwi-IP ye-interface yememori yangaphandle kunye nejeneretha ye-traffic, ukubonakalisa ukupasa jikelele okanye imeko yokungaphumeleli.

Umzobo 8. Ukulinganisa Example Design

Ukuba usebenzisa iPing Pong PHY isici, ukulinganisa exampUyilo lwe-le lubandakanya iijeneretha ezimbini zendlela yokukhupha imiyalelo kwizixhobo ezimbini zememori ezizimeleyo ngokusebenzisa abalawuli ababini abazimeleyo kunye ne-PHY eqhelekileyo, njengoko kuboniswe kulo mfanekiso ulandelayo.

Umzobo 9. Ukulinganisa Example Uyilo lwePing Pong PHY

Ukuba usebenzisa i-RLDRAM 3, ijenereyitha yetrafikhi kwi-simulation example uyilo inxibelelana ngokuthe ngqo ne-PHY isebenzisa i-AFI, njengoko kubonisiwe kulo mfanekiso ulandelayo.

Example UYilo lweTab yoNxibelelwano

Umhleli weparameter uquka iExample yoYilo ithebhu ekuvumela ukuba wenze iparameter kwaye uvelise i-ex yakhoample uyilo.l

Umzobo 11. Eksample Tab yoYilo kuMhleli weParameter yoNxibelelwano lweMemori yaNgaphandle

Ifumaneka Example iCandelo loYilo
I Khetha uyilo lokutsalwa likuvumela ukuba ukhethe i ex oyifunayoample uyilo. Okwangoku, i-EMIF Example Uyilo lolona khetho lukhoyo, kwaye lukhethwa ngokungagqibekanga.
