Ukutholwa Kwephutha Nokulungisa Kumadivayisi e-SmartFusion2 asebenzisa i-DDR Memory

Isingeniso
Esimweni esisodwa esicasulayo (SEU) esithintekayo, inkumbulo yokufinyelela okungahleliwe (RAM) ijwayele ukuba namaphutha esikhashana abangelwa ama-ion asindayo.
Lo mbhalo uchaza amandla e-EDAC e-SoC FPGA, asetshenziswa ezinhlelweni ezinezinkumbulo ezixhunywe nge-microcontroller subsystem (MSS) DDR (MDDR).
Izilawuli ze-EDAC ezisetshenziswe kumadivayisi we-SmartFusion2 zisekela ukulungiswa kwephutha elilodwa nokutholwa kwamaphutha aphindwe kabili (SECDED). Zonke izinkumbulo—inkumbulo yokufinyelela engahleliwe ethuthukisiwe (i-eSRAM), i-DDR, i-DDR (LPDDR) yamandla aphansi—ngaphakathi kwemishini ye-SmartFusion2 MSS ivikelwe yi-SECDED. Imemori yokufinyelela engahleliwe ye-DDR evumelanisiwe (i-SDRAM) ingaba i-DDR2, i-DDR3, noma i-LPDDR1, kuye ngokucushwa kwe-MDDR namandla e-ECC.
I-subsystem ye-SmartFusion2 MDDR isekela ukuminyana kwememori kufika ku-4 GB. Kule demo, ungakhetha noma iyiphi indawo yememori engu-1 GB endaweni yekheli le-DDR (0xA0000000 kuya ku-0xDFFFFFFF).
Uma i-SECDED inikwe amandla:

• Umsebenzi wokubhala uhlanganisa futhi wengeze amabhithi angu-8 ekhodi engu-SECDED (kuzo zonke izingcezu ezingama-64 zedatha)
• Umsebenzi wokufunda ufunda futhi uhlole idatha ngokumelene nekhodi egciniwe engu-SECDED ukuze kusekelwe ukulungiswa kwephutha elingu-1-bit kanye nokutholwa kwephutha lama-2-bit.

Umfanekiso olandelayo uchaza umdwebo webhlokhi we-SmartFusion2 EDAC ku-DDR SDRAM.

Umfanekiso 1 • Umdwebo Webhulokhi Wezinga eliphezulu

Idemo Design
Idizayini yedemo files ayatholakala ukuze alandwe kusuka kumzila olandelayo ku-Microsemi webindawo: http://soc.microsemi.com/download/rsc/?f=m2s_dg0618_liberov11p8_df
Idizayini yedemo files zihlanganisa:

• Ukucushwa kwe-DDR File
• DDR_EDAC
• Ukuhlela files
• I-GUI iyasebenza
• Ngifunde file

Umfanekiso olandelayo uchaza ukwakheka kwezinga eliphezulu lomklamo files. Ukuze uthole imininingwane eyengeziwe, bheka i-readme.txt file.

Umfanekiso 2 • Idizayini Yedemo Isakhiwo Sezinga eliphezulu

Ukuqaliswa Kwedizayini Yedemo
Isistimu engaphansi ye-MDDR inesilawuli se-EDAC esizinikele. I-EDAC ithola iphutha le-1-bit noma iphutha le-2-bit lapho idatha ifundwa kumemori. Uma i-EDAC ithola iphutha le-1-bit, isilawuli se-EDAC silungisa ingxenye yephutha. Uma i-EDAC inikwe amandla kuwo wonke amaphutha e-1-bit kanye ne-2-bit, izibali zamaphutha ezihambisanayo kumarejista esistimu ziyandiswa futhi iziphazamiso ezihambisanayo namasiginali webhasi wephutha endwangu ye-FPGA ayakhiqizwa.
Lokhu kwenzeka ngesikhathi sangempela. Ukuze ubonise lesi sici SECDED, iphutha lethulwa mathupha futhi kuqashelwe ukutholwa nokulungiswa.
Lo mklamo wedemo ubandakanya ukuqaliswa kwezinyathelo ezilandelayo:

1. Nika amandla i-EDAC
2. Bhala idatha ku-DDR
3. Funda idatha evela ku-DDR
4. Khubaza i-EDAC
5. Konakele izingcezu ezi-1 noma ezi-2
6. Bhala idatha ku-DDR
7. Nika amandla i-EDAC
8. Funda idatha
9. Esimeni sephutha le-1-bit, isilawuli se-EDAC silungisa iphutha, sibuyekeza amarejista esimo esihambisanayo, futhi sinikeze idatha ebhalwe ku-Isinyathelo sesi-2 emsebenzini wokufunda owenziwe esinyathelweni sesi-8.
10. Esimeni sephutha le-2-bit, ukuphazamiseka okuhambisanayo kukhiqizwa futhi uhlelo lokusebenza kufanele lulungise idatha noma luthathe isinyathelo esifanele kusibambi sokuphazamisa. Lezi zindlela ezimbili ziboniswa kule demo.

Ukuhlola okubili kwenziwa kule demo: ukuhlolwa kweluphu nokuhlola okwenziwa ngesandla futhi kuyasebenza kuwo womabili amaphutha e-1-bit kanye ne-2-bit.

I-Loop Test
Ukuhlolwa kwe-Loop kwenziwa lapho amadivayisi we-SmartFusion2 ethola umyalo wokuhlola iluphu ku-GUI. Ekuqaleni, zonke izibali zamaphutha kanye namarejista ahlobene ne-EDAC abekwe esimweni se-RESET.
Izinyathelo ezilandelayo zenziwa ekuphindaphindweni ngakunye.

1. Nika amandla isilawuli se-EDAC
2. Bhala idatha endaweni ethile yememori ye-DDR
3. Khubaza isilawuli se-EDAC
4. Bhala idatha yephutha elingu-1-bhithi noma elingu-2 endaweni efanayo yenkumbulo ye-DDR
5. Nika amandla isilawuli se-EDAC
6. Funda idatha endaweni efanayo yememori ye-DDR
7. Thumela ukutholwa kwephutha le-1-bit noma i-2-bit kanye nedatha ye-1-bit yokulungisa iphutha uma kwenzeka iphutha le-1-bit ku-GUI

Ukuhlolwa Kwezandla
Le ndlela ivumela ukuhlola mathupha kokutholwa kwephutha le-1-bit nokulungiswa kanye nokutholwa kwephutha le-2-bit kukheli lememori ye-DDR (0xA0000000 kuya ku-0xDFFFFFFF) ngokuqalisa. Iphutha le-1-bit/2-bit lethulwa mathupha ekhelini lememori ye-DDR ekhethiwe. Idatha enikeziwe ibhalelwa endaweni yememori ye-DDR ekhethiwe futhi i-EDAC inikwe amandla. Idatha yephutha engu-1-bit noma engu-2 eyonakele ibhalwa endaweni efanayo yememori lapho i-EDAC ivaliwe. Ulwazi ngephutha elitholiwe le-1-bit noma i-2-bit lilogwa lapho idatha ifundwa endaweni efanayo yememori lapho i-EDAC inikwe amandla. Isilawuli se-DMA esisebenza kahle kakhulu
(HPDMA) isetshenziselwa ukufunda idatha evela kumemori ye-DDR. Isibambi sokuphazamisa sokuthola amabhithi amabili sisetshenziswa ukuze sithathe isinyathelo esifanele uma kutholwa iphutha le-2-bit.
Umfanekiso olandelayo uchaza imisebenzi yedemo ye-EDAC.

Umfanekiso 3 • Ukugeleza Kwedizayini

Qaphela: Ngephutha le-2-bit, lapho iphrosesa ye-Cortex-M3 ifunda idatha, ukwenziwa kwekhodi kungena kusibambi sephutha eliqinile, njengoba ukuphazamiseka okutholiwe sekwephuzile ukuze iphrosesa iphendule. Ngesikhathi iphendula ekuphazamisekeni, kungenzeka ukuthi isivele iyidlulisile idatha futhi yethule umyalo ngephutha. Ngenxa yalokho, i-HRSP iyayeka ukucubungula idatha engalungile. Ukutholwa kwephutha le-2-bit kusebenzisa i-HPDMA ukufunda idatha kusukela kundawo yekheli le-DDR, eyalela iphrosesa ukuthi ifunde idatha inephutha le-2-bit futhi isistimu kufanele ithathe isinyathelo esifanele ukuze ilulame (I-ECC iphazamise Isibambi).
