Ukufunyanwa kwempazamo kunye noLungiso kwiiDevices ze-SmartFusion2 usebenzisa i-DDR Memory

Intshayelelo
Kwisiganeko esisodwa sokuphazamiseka (SEU) indawo echaphazelekayo, imemori yokufikelela ngokungahleliwe (RAM) ixhomekeke kwiimpazamo ezidlulayo ezibangelwa ii-ion ezinzima.
Olu xwebhu luchaza izakhono ze-EDAC ze-SoC FPGA, ezisetyenziswa kwizicelo ezineenkumbulo eziqhagamshelwe nge-microcontroller subsystem (MSS) DDR (MDDR).
Abalawuli be-EDAC abaphunyezwe kwii-SmartFusion2 izixhobo zixhasa ukulungiswa kwempazamo enye kunye nokufunyanwa kwephutha eliphindwe kabini (SECDED). Zonke iinkumbulo-eziphuculweyo ze-static random access memory (eSRAM), i-DDR, i-DDR (LPDDR) ephantsi kwamandla-ngaphakathi kwezixhobo ze-SmartFusion2 MSS zikhuselwe yi-SECDED. I-DDR synchronous dynamic access memory (SDRAM) ingaba yiDDR2, DDR3, okanye LPDDR1, ngokuxhomekeke kuqwalaselo lwe-MDDR kunye nezixhobo ze-ECC zehardware.
Inkqubo ephantsi ye-SmartFusion2 MDDR ixhasa ukuxinana kwememori ukuya kuthi ga kwi-4 GB. Kule demo, unokukhetha nayiphi na indawo yememori ye-1 GB kwindawo yedilesi ye-DDR (0xA0000000 ukuya kwi-0xDFFFFFFF).
Xa i-SECDED yenziwe yasebenza:

• Umsebenzi wokubhala ubala kwaye wongeze iibhithi ezisi-8 zekhowudi ye-SECDED (kuzo zonke iibhithi zedatha ezingama-64)
• Umsebenzi wokufunda ufunda kwaye ujonge idatha ngokuchasene nekhowudi egciniweyo SECDED ukuxhasa ukulungiswa kwemposiso ye-1-bit kunye nobhaqo lwemposiso ye-2-bit.

Lo mzekeliso ulandelayo uchaza umzobo webhloko we-SmartFusion2 EDAC kwi-DDR SDRAM.

Umzobo 2 • Uyilo lweDemo olukwiNqanaba eliPhezulu leSakhiwo

Ukuphunyezwa koYilo lweDemo
Inkqubo ephantsi ye-MDDR inomlawuli ozinikeleyo we-EDAC. I-EDAC ibona impazamo ye-1-bit okanye impazamo ye-2-bit xa idatha ifundwa kwimemori. Ukuba i-EDAC ibona impazamo ye-1-bit, umlawuli we-EDAC ulungisa ibit yempazamo. Ukuba i-EDAC yenziwe yasebenza kuzo zonke iimpazamo ze-1-bit kunye ne-2-bit, izixhobo zokubala ezihambelanayo kwiirejista zesistim ziyanyuswa kwaye iziphazamiso ezihambelanayo kunye neempawu zebhasi zempazamo kwilaphu leFPGA ziyenziwa.
Oku kwenzeka ngexesha lokwenyani. Ukubonisa eli nqaku le-SECDED, impazamo yaziswa ngesandla kwaye yabonwa ukubhaqwa kunye nokulungiswa.
Olu yilo lwedemo lubandakanya ukuphunyezwa kwala manyathelo alandelayo:

1. Yenza i-EDAC isebenze
2. Bhala idatha kwi-DDR
3. Funda idatha esuka kwi-DDR
4. Khubaza i-EDAC
5. Urhwaphiliza i-1 okanye i-2 bits
6. Bhala idatha kwi-DDR
7. Yenza i-EDAC isebenze
8. Funda idatha
9. Kwimeko yempazamo ye-1-bit, umlawuli we-EDAC ulungisa impazamo, uhlaziya iirejista zesimo esihambelanayo, kwaye unike idatha ebhalwe kwiNyathelo 2 kumsebenzi wokufunda owenziwe kwiNyathelo lesi-8.
10. Kwimeko yempazamo ye-2-bit, uphazamiseko oluhambelanayo luyenziwa kwaye isicelo kufuneka silungise idatha okanye sithathe isenzo esifanelekileyo kwisibambi sokuphazamiseka. Ezi ndlela zimbini ziboniswa kule demo.

Iimvavanyo ezimbini ziphunyezwe kule demo: uvavanyo lwe-loop kunye novavanyo lwe-manual kwaye lusebenza kuzo zombini iimpazamo ze-1-bit kunye ne-2-bit.

Uvavanyo lweLoop
Uvavanyo lwe-Loop lwenziwa xa izixhobo ze-SmartFusion2 zifumana umyalelo wovavanyo lwe-loop kwi-GUI. Ekuqaleni, zonke izixhobo zokubala zeempazamo kunye neerejista ezinxulumene ne-EDAC zibekwe kwimeko ye-RESET.
La manyathelo alandelayo ayenziwa kuphindaphindo ngalunye.

1. Yenza isilawuli se-EDAC sisebenze
2. Bhala idatha kwindawo ethile yememori ye-DDR
3. Khubaza isilawuli se-EDAC
4. Bhala i-1-bit okanye i-2-bit yedatha yempazamo eyenziwe kwindawo efanayo yememori ye-DDR
5. Yenza isilawuli se-EDAC sisebenze
6. Funda idatha kwindawo efanayo yememori ye-DDR
7. Thumela i-1-bit okanye i-2-bit yokufunyaniswa kwemposiso kunye nedatha ye-1-bit yokulungiswa kwempazamo kwimeko yempazamo ye-1-bit kwi-GUI.

Uvavanyo lwencwadi
Le ndlela ivumela uvavanyo lwe-manual ye-1-bit yokufumanisa impazamo kunye nokulungiswa kunye ne-2-bit yephutha lokubona idilesi yememori ye-DDR (0xA0000000 ukuya kwi-0xDFFFFFFF) ngokuqalisa. Impazamo ye-1-bit/2-bit yaziswa ngesandla kwidilesi yememori ye-DDR ekhethiweyo. Idatha enikiweyo ibhalwa kwindawo yememori ye-DDR ekhethiweyo kunye ne-EDAC evuliwe. I-1-bit okanye i-2-bit yedatha eyonakeleyo ibhalwa kwindawo enye yememori kunye ne-EDAC evaliwe. Ulwazi ngempazamo echongiweyo ye-1-bit okanye i-2-bit ifakwe xa idatha ifundwa kwindawo enye yememori kunye ne-EDAC evuliwe. Umlawuli weDMA osebenza kakhulu
(HPDMA) isetyenziselwa ukufunda idatha kwimemori ye-DDR. Isibambi sokuphazamiseka kwe-bit-bit siphunyeziwe ukuthatha inyathelo elifanelekileyo xa kufunyenwe impazamo ye-2-bit.
Lo mzekeliso ulandelayo uchaza imisebenzi yedemo ye-EDAC.

Umzobo 3 • Ukuhamba koYilo

Phawula: Ngempazamo ye-2-bit, xa iprosesa ye-Cortex-M3 ifunda idatha, ukuphunyezwa kwekhowudi kuya kwi-hard fault handler, njengoko ukuphazamiseka okufunyenweyo kusemva kwexesha ukuba iprosesa iphendule. Ngethuba iphendula ukuphazamisa, inokuba sele idlulile idatha kwaye iqalise ngengozi umyalelo. Ngenxa yoko, i-HRSP iyayeka ukusetyenzwa kwedatha engachanekanga. Ubhaqo lwemposiso ye-2-bit isebenzisa i-HPDMA ukufunda idatha ukusuka kwindawo yedilesi ye-DDR, eyalela umqhubekekisi ukuba ufunda i-data enempazamo ye-2-bit kwaye inkqubo kufuneka ithathe inyathelo elifanelekileyo ukubuyisela (i-ECC iphazamise i-Handler).
