I-Microsemi SmartDesign MSS eZinziselwe iMemori engaguqukiyo (eNVM)
Intshayelelo
I-MSS Embekelwe kwiMemori eNgenabungozi (eNVM) yenza ukuba wenze imimandla yenkumbulo eyahlukeneyo (abaxumi) abafuna ukucwangciswa kwisixhobo se-eNVM block(s).
Kolu xwebhu sichaza ngokweenkcukacha indlela yokuqwalasela iibhloko ze-eNVM. Ukufumana iinkcukacha ezithe vetshe malunga ne-eNVM, nceda ubhekisele kwiSikhokelo soMsebenzisi we-Actel SmartFusion Microcontroller.
Ulwazi oluBalulekileyo Malunga namaPhepha oMsebenzisi we-eNVM
Umqwalaseli we-MSS usebenzisa inani elithile lamaphepha e-eNVM omsebenzisi ukugcina uqwalaselo lwe-MSS. La maphepha abekwe phezulu kwisithuba sedilesi ye-eNVM. Inani lamaphepha liyaguquguquka ngokusekelwe kuqwalaselo lwakho lwe-MSS (ACE, GPIOs kunye ne-eNVM Init Clients). Ikhowudi yesicelo sakho akufuneki ibhale kula maphepha omsebenzisi njengoko inokubangela ukusilela kwexesha lokusebenza kuyilo lwakho. Qaphela kwakhona ukuba la maphepha onakaliswe ngempazamo, inxalenye ayisayi kuphinda iqale kwaye iyakufuna ukucwangciswa kwakhona.
Idilesi yokuqala 'egciniweyo' ingabalwa ngolu hlobo lulandelayo. Emva kokuba i-MSS yenziwe ngempumelelo, vula i-eNVM configurator kwaye urekhode inani lamaphepha akhoyo aboniswe kwiqela leNkcazo yosetyenziso kwiphepha eliphambili. Idilesi yokuqala egciniweyo ichazwa ngolu hlobo:
first_reserved_address = 0x60000000 + (amaphepha_afumanekayo * 128)
Ukudala kunye nokuQinisekisa abaxhasi
Ukudala abaxhasi
Iphepha eliphambili lomqwalaseli we-eNVM likwenza ukuba wongeze abaxhasi abohlukeneyo kwibhloko yakho ye-eNVM. Kukho iintlobo ezi-2 ezikhoyo zabaxhasi:
- Umxhasi woGcino lweDatha- Sebenzisa ugcino lwedatha ukuchaza ummandla wenkumbulo eqhelekileyo kwibhloko ye-eNVM. Lo mmandla ungasetyenziselwa ukubamba ikhowudi yesicelo sakho okanye nawuphi na omnye umxholo wedatha onokuthi isicelo sakho siwufune.
- Ukuqaliswa komthengi - Sebenzisa umxhasi wokundulula ukuchaza indawo yenkumbulo efuna ukukhutshelwa ngexesha lokuqalisa inkqubo kwindawo ekhankanyiweyo yedilesi yeCortex-M3.
Igridi engundoqo ikwabonisa iimpawu zabo nabaphi na abathengi abamiselweyo. Ezi mpawu zezi:
- Uhlobo loMthengi- Uhlobo lomxhasi olongezwe kwisixokelelwano

Inkumbulo File Iifomathi
Inkumbulo elandelayo file iifomati ziyafumaneka njengegalelo files kwi-eNVM Configurator:
- INTEL-HEX
- MOTOROLA S-irekhodi
- Actel BINARY
- I-ACTEL-HEX
INTEL-HEX
Umgangatho weshishini file. Izandiso zi-HEX kunye ne-IHX. Umzekeloample, file2.hex okanye file3.ihx.
Ifomati eqhelekileyo eyenziwe yi-Intel. Imixholo yememori igcinwe kwi-ASCII files usebenzisa abalinganiswa abanehexadecimal. Ngamnye file iqulathe uthotho lweerekhodi (imigca yokubhaliweyo) ehlulwe ngomgca omtsha, '\n', abasebenzi kunye nerekhodi ngalinye liqala ngophawu ':'. Ngolwazi oluthe kratya malunga nale fomati, bhekisa kuxwebhu lweNgcaciso yeFomathi yeRekhodi ye-Intel-Hex ekhoyo kwi web (khangela i-Intel Hexadecimal Object File ezininzi exampkancinci).
IRekhodi ye-Intel Hex yenziwe ngamacandelo amahlanu kwaye icwangciswe ngolu hlobo lulandelayo:
:llaaaatt[dd...]cc
Apho:
- : yikhowudi yokuqala yerekhodi nganye ye-Intel Hex

Apho u-11 eyi-LSB kunye ne-FF yi-MSB.
MOTOROLA S-irekhodi
Umgangatho weshishini file. File ulwandiso yi S, ezifana file4.s
Le fomati isebenzisa i-ASCII files, abalinganiswa be-hex, kunye neerekhodi zokuchaza umxholo wememori ngendlela efanayo ne-Intel-Hex eyenza ngayo. Jonga kuxwebhu lwenkcazo yerekhodi ye-Motorola ngolwazi oluthe kratya kule fomati (khangela i-Motorola S-record inkcazo kwiiex eziliqelaampkancinci). Umphathi woMxholo we-RAM usebenzisa kuphela i-S1 ngokusebenzisa iintlobo zerekhodi ze-S3; abanye abahoywa.
Umahluko omkhulu phakathi kwe-Intel-Hex kunye ne-Motorola S-rekhoda ziifomathi zerekhodi, kunye nempazamo eyongezelelweyo yokujonga iimpawu ezifakwe kwi-Motorola S.
Kuzo zombini iifomathi, umxholo wememori uxelwa ngokubonelela ngedilesi yokuqala kunye neseti yedatha. Iibhithi eziphezulu zeseti yedatha zilayishwa kwidilesi yokuqala kwaye intsalela iphuphuma kwiidilesi ezikufutshane kude kube yilapho yonke idatha isetyenzisiwe.
I-Motorola S-rekhoda yenziwe ngamabala ayi-6 kwaye icwangciswe ngolu hlobo lulandelayo:
Hlalani[dd...]cc
Apho:
- S yikhowudi yokuqala yerekhodi ngalinye le-Motorola S
- t luhlobo lwerekhodi, ichaza indawo yedatha
- ll lubalo lwe-byte yendawo yedatha
- aaaa yi-16-bit idilesi yesiqalo sendawo yememori yedatha. Idilesi inkulu endian.
- [dd...] lulandelelwano lwe-n bytes yedatha; n ilingana noko kuchaziweyo kumhlaba well
- cc yitshekhisum yokubala, idilesi, kunye nedatha
Example Motorola S-Record:
S10a0000112233445566778899FFFA
Apho u-11 eyi-LSB kunye ne-FF yi-MSB.
Actel Binary
Eyona fomati ilula yememori. Inkumbulo nganye file iqulathe imiqolo emininzi njengoko kukho amagama. Umqolo ngamnye ligama elinye, apho inani lamasuntswana okubini lilingana nobukhulu begama ngamasuntswana. Le fomati inesivakalisi esingqongqo kakhulu. Ubungakanani begama kunye nenani lemiqolo kufuneka lingqinelane ngokuchanekileyo. I file ulwandiso yi-MEM; umzekeloample, file1.mem.
Example: Ubunzulu 6, Ububanzi yi-8
01010011
11111111
01010101
11100010
10101010
11110000
I-Actel HEX
Idilesi elula/ifomati yedatha. Zonke iidilesi ezinomxholo zichaziwe. Iidilesi ezingenasiqulatho sichaziweyo ziya kuqalwa zibe zero. I file ulwandiso yi AHX, njenge filex.ahx. Ifomati yile:
AA:D0D1D2
Apho i-AA iyindawo yedilesi kwi-hex. I-D0 yi-MSB kwaye i-D2 yi-LSB.
Ubungakanani bedatha kufuneka bungqinelane nobukhulu begama. Eksample: Ubunzulu 6, Ububanzi yi-8
00:FF
01:AB
02:CD
03:EF
04:12
05:BB
Zonke ezinye iidilesi ziya kuba zero.
Ukutolika umxholo weMemori
Ngokupheleleyo vs. INtetho enxulumene nesihlobo
KwiNtetho eNxulumeneyo, iidilesi ezikumxholo wememori file khange igqibe ukuba umxhasi ubekwe phi kwinkumbulo. Uchaza indawo yomthengi ngokungenisa idilesi yokuqala. Oku kuba yidilesi ka-0 kumxholo wememori file imbono kwaye umxhasi uhlaliswa ngokufanelekileyo.
Umzekeloample, ukuba sibeka umxhasi kwi-0x80 kunye nomxholo wememori file imi ngolu hlobo lulandelayo:
Idilesi: 0x0000 idatha: 0102030405060708
Address: 0x0008 data: 090A0B0C0D0E0F10
Emva koko isethi yokuqala ye-bytes yale datha ibhaliwe ukujongana ne-0x80 + 0000 kwibhloko ye-eNVM. Isethi yesibini yee-bytes ibhaliwe kwidilesi 0x80 + 0008 = 0x88, njalo njalo.
Ngaloo ndlela iidilesi kumxholo wememori file zinxulumene nomxhasi ngokwakhe. Apho umxhasi ubekwe kwinkumbulo yesibini.
Kwidilesi epheleleyo, umxholo wememori file ixela apho umthengi abekwe khona kwibhloko ye-eNVM. Ke idilesi kumxholo wememori file kuba umxhasi uba ngokupheleleyo kuyo yonke ibhloko ye-eNVM. Nje ukuba wenze ukhetho olupheleleyo lwedilesi, isoftware ikhupha eyona dilesi incinci kumxholo wememori file kwaye isebenzisa loo dilesi njengedilesi yokuqala yomthengi.
