Microsemi IGLOO2 HPMS DDR Uqwalaselo Controller
Intshayelelo
I-IGLOO2 HPMS inomlawuli we-DDR edibeneyo (HPMS DDR). Lo mlawuli we-DDR ujonge ukulawula imemori ye-DDR ecinyiweyo. Umlawuli we-HPMS DDR unokufumaneka kwi-HPMS (usebenzisa i-HPDMA) kunye nakwilaphu le-FPGA.
Xa usebenzisa i-System Builder ukwakha ibhloko yenkqubo equka i-HPMS DDR, i-System Builder iqwalasela isilawuli se-HPMS DDR yakho ngokusekelwe kumangeno kunye nokhetho lwakho.
Akukho luhlu lwahlukileyo lwe-HPMS DDR lufunwa ngumsebenzisi. Ngeenkcukacha, nceda ubhekisele kwi-IGLOO2 System Builder User's Guide.
Umakhi weNkqubo
Umakhi weNkqubo
Kwi-em Umakhi ukuqwalasela i-HPMS DDR ngokuzenzekelayo.
- KwiNkalo yeSixhobo ithebhu yoMakhi weNkqubo, khangela iMemori ye-HPMS yangaphandle ye-DDR (HPMS DDR).
- KwiMemori isithuba, khetha i-DDR ye-Memory Type:
- I-DDR2
- I-DDR3
- LPDDR
- Khetha Ububanzi bememori ye-DDR: 8, 16 okanye 32
- Jonga i-ECC ukuba ufuna ukuba ne-ECC ye-DDR.
- Ngenisa ixesha lokuseta imemori ye-DDR. Eli lixesha imemori ye-DDR ifuna ukuqalisa.
- Cofa uBumbeko lweRejista yokungenisa ngaphandle ukungenisa amaxabiso oBhalisa kwi-FDDR kumbhalo osele ukho file equlathe amaxabiso erejista. Jonga iTheyibhile yoku-1 malunga noqwalaselo lwerejista file isintaksi.
I-Libero igcina ngokuzenzekelayo le datha yoqwalaselo kwi-eNVM. Ekusetweni ngokutsha kweFPGA, le datha yoqwalaselo iya kukhutshelwa ngokuzenzekelayo kwiHPMS DDR.

Uqwalaselo loMlawuli we-HPMS DDR
Xa usebenzisa i-HPMS DDR Controller ukufikelela kwi-DDR Memory yangaphandle, i-DDR Controller kufuneka iqaliswe ngexesha lokuqalisa. Oku kwenziwa ngokubhala idatha yoqwalaselo kwiirejista zoqwalaselo lomlawuli we-DDR. Kwi-IGLOO2, i-eNVM igcina idatha yoqwalaselo lwerejista kwaye emva kokusetha kwakhona kweFPGA, idatha yoqwalaselo ikopishwa kwi-eNVM ukuya kwiirejista ezinikezelweyo zeHPMS DDR ukuze kuqaliswe.
Iirejista zoLawulo lwe-HPMS DDR
UMlawuli we-HPMS DDR uneseti yeerejista ekufuneka ziqwalaselwe ngexesha lokusebenza. Amaxabiso oqwalaselo kwezi rejista amele iiparamitha ezahlukeneyo, ezifana nemowudi ye-DDR, ububanzi be-PHY, imo yokugqabhuka, kunye ne-ECC. Ukufumana iinkcukacha ezipheleleyo malunga neerejista zoqwalaselo lomlawuli we-DDR nceda ubhekisele kwiSikhokelo soMsebenzisi weMicrosemi IGLOO2
HPMS MDDR Iirejista Uqwalaselo
Ukucacisa amaxabiso oBhaliso lweDDR:
- Sebenzisa umhleli wombhalo ngaphandle kweLibero SoC, lungiselela isicatshulwa file equlethe amagama kunye namaxabiso eRejista, njengoko kuMfanekiso 1-1.
- Ukusuka kwiMemori yoMakhi weSixokelelwano isithuba, cofa uLungiselelo lokuBhalisa ngaphandle.
- Lawula uye kwindawo yokubhaliweyo koLungiselelo loBhaliso file oyilungisileyo kwiNyathelo 1 kwaye ukhethe i file ukungenisa.
Umzobo 1-1 • Bhalisa iDatha yoLungiso – iFomathi yokubhaliweyo
HPMS DDR Ukuqaliswa
Idatha yoLungiselelo yoBhaliso oyingenisayo kwi-HPMS DDR ilayishwe kwi-eNVM kwaye ikhutshelwe kwiirejista zoqwalaselo ze-HPMS DDR ekusetweni ngokutsha kwe-FPGA. Akukho ntshukumo yomsebenzisi ifunekayo ukuze kuqaliswe i-HPMS DDR ngexesha lokusebenza. Oku kuqalwa ngokuzenzekelayo kukwayimodeli yokulinganisa.
