Chitsimikizo
Microsemi sapereka chitsimikizo, choyimira, kapena chitsimikiziro chokhudza zomwe zili pano kapena kuyenerera kwa katundu ndi ntchito zake pazifukwa zinazake, komanso Microsemi sakhala ndi udindo uliwonse chifukwa cha ntchito kapena kugwiritsa ntchito mankhwala kapena dera lililonse. Zogulitsa zomwe zimagulitsidwa apa ndi zina zilizonse zomwe zimagulitsidwa ndi Microsemi zakhala zikuyesedwa pang'ono ndipo siziyenera kugwiritsidwa ntchito limodzi ndi zida zofunikira kwambiri kapena ntchito. Zochita zilizonse zimakhulupirira kuti ndizodalirika koma sizinatsimikizidwe, ndipo Wogula amayenera kuchita ndikumaliza ntchito zonse ndi kuyesa kwina kwazinthuzo, payekha komanso, kapena kuyikamo, zogulitsa zilizonse. Wogula sadzadalira deta iliyonse ndi machitidwe kapena magawo operekedwa ndi Microsemi. Ndiudindo wa Wogula kuti adziyese yekha ngati zogulitsa zilizonse ndi kuyesa ndikutsimikizira zomwezo. Zomwe zimaperekedwa ndi Microsemi pansipa zimaperekedwa "monga momwe zilili, zili kuti" komanso zolakwa zonse, ndipo chiopsezo chonse chokhudzana ndi chidziwitso choterocho chiri kwathunthu ndi Wogula. Microsemi sapereka, momveka bwino kapena momveka bwino, kwa chipani chilichonse ufulu wa patent, malayisensi, kapena ufulu wina uliwonse wa IP, kaya zokhudzana ndi chidziwitsocho kapena chirichonse chofotokozedwa ndi chidziwitso choterocho.

Kuyambitsa ndi Kukonzekera
PolarFire SoC FPGAs amagwiritsa ntchito mabwalo apamwamba opangira mphamvu kuti awonetsetse kuti mphamvu zodalirika zimayatsidwa pakuyatsa ndikukhazikitsanso. Mukayatsa ndikukhazikitsanso, kutsatizana kwa boot-up kwa PolarFire SoC FPGA kumatsatira Power-on reset (POR), boot Device, Design initialization, Microcontroller Subsystem (MSS) pre-boot, ndi MSS user boot. Chikalatachi chikufotokoza za MSS pre-boot ndi MSS User Boot. Kuti mumve zambiri za POR, Boot ya Chipangizo ndi Kuyambitsa Kapangidwe, onani UG0890: PolarFire SoC FPGA Power-Up ndi Reset Guide User.

Njira Yoyambira
Kutsatizana kwa boot-up kumayamba pomwe PolarFire SoC FPGA imayendetsedwa kapena kukonzanso. Zimatha pamene purosesa ili wokonzeka kugwiritsa ntchito pulogalamu. Kuwombera uku kumadutsa m'ma s angapotages isanayambe kuchitidwa kwa mapulogalamu.
Ntchito zingapo zimachitika panthawi ya Boot-up yomwe imaphatikizapo kukhazikitsanso mphamvu kwa hardware, kuyambika kwa peripheral, kuyambitsa kukumbukira, ndi kutsitsa pulogalamu yomwe imatanthauzidwa ndi wogwiritsa ntchito kuchokera ku kukumbukira kosasunthika kupita ku kukumbukira kosasinthika kuti aphedwe.
Chithunzi chotsatira chikuwonetsa magawo osiyanasiyana amayendedwe a Boot-up.

MSS Pre-Boot
Mukamaliza bwino Design Initialization, MSS Pre-boot imayamba kuchita. MSS imatulutsidwa kuchokera pakukonzanso pambuyo pomaliza njira zonse zoyambira. Woyang'anira dongosolo amayang'anira kukonza, kuyambitsa, ndi kukonza zida. MSS Pre-boot sikuchitika ngati chipangizo chokonzedwacho chakonzedwa kuti chiyimitse chowongolera.
Gawo loyambira la MSS loyambira limalumikizidwa ndi firmware yowongolera makina, ngakhale itha kugwiritsa ntchito E51 mu MSS Core Complex kuchita magawo ena a pre-boot sequence.
Zochitika zotsatirazi zimachitika panthawi ya MSS pre-boot stage:
- Kukweza kwa MSS yophatikizidwa Non-Volatile Memory (eNVM)
- Kuyambitsa kukonzanso kwapang'onopang'ono komwe kumalumikizidwa ndi cache ya MSS Core Complex L2
- Kutsimikizika kwa code ya boot ya Wogwiritsa (ngati njira ya Boot Yotetezeka ya Mtumiki yayatsidwa)
- Perekani MSS yogwira ntchito ku Code Boot Code
MSS Core Complex imatha kukhazikitsidwa mu imodzi mwazinthu zinayi. Gome lotsatirali limatchula zosankha za MSS pre-boot, zomwe zingathe kukonzedwa ndikukonzedwa mu sNVM. Njira yoyambira imatanthauzidwa ndi gawo la ogwiritsa U_MSS_BOOTMODE[1:0]. Deta yowonjezera ya kasinthidwe ka jombo imadalira mode ndipo imatanthauzidwa ndi wogwiritsa ntchito U_MSS_BOOTCFG (onani Table 3, tsamba 4 ndi Table 5, tsamba 6).
Gulu 1 • MSS Core Complex Boot Modes

Ngati MSS sinakonzedwe (mwachitsanzoample, chida chopanda kanthu), ndiye MSS Core Complex imapanga pulogalamu ya boot ROM yomwe imagwira mapurosesa onse mopanda malire mpaka chosokoneza chilumikizane ndi chandamale. Zolembera za boot vector zimasunga mtengo wake mpaka chipangizocho chikhazikitsidwenso kapena kusinthidwa kwatsopano kwa boot mode. Pazida zokhazikitsidwa, njirayi imatha kukhazikitsidwa pogwiritsa ntchito ma

Boot yopanda chitetezo
Munjira iyi, MSS Core Complex imagwira kuchokera ku adilesi yodziwika ya eNVM popanda kutsimikizika. Imapereka njira yofulumira kwambiri ya boot, koma palibe kutsimikizika kwa chithunzi cha code. Adilesi ikhoza kufotokozedwa pokhazikitsa U_MSS_BOOTADDR mu Libero Configurator. Njirayi itha kugwiritsidwanso ntchito poyambira kuchokera pamtundu uliwonse wa FPGA Fabric memory kudzera pa FIC. Njira iyi ikugwiritsidwa ntchito pogwiritsa ntchito

Boot Yotetezedwa Yogwiritsa Ntchito
Njirayi imalola wogwiritsa ntchito kukhazikitsa boot yawo yotetezedwa ndipo code code yotetezedwa ya wosuta imayikidwa mu sNVM. sNVM ndi 56 KB kukumbukira kosasunthika komwe kumatha kutetezedwa ndi Physically Unclonable Function (PUF) yomangidwa. Njira yoyambira iyi imawonedwa ngati yotetezedwa chifukwa masamba a sNVM olembedwa kuti ROM ndi osasinthika. Pa mphamvu, woyang'anira dongosolo amakopera wogwiritsa ntchito boot code yotetezedwa kuchokera ku sNVM kupita ku Data Tightly Integrated Memory (DTIM) ya E51 Monitor core. E51 imayamba kugwiritsa ntchito nambala yotetezedwa ya wosuta.
Ngati kukula kwa code ya boot yotetezedwa ndi yoposa kukula kwa DTIM ndiye wogwiritsa ntchito ayenera kugawa code code mu masekondi awiri.tages. sNVM ikhoza kukhala ndi ma stage ya machitidwe a boot osuta, omwe angapangitse kutsimikizika kwa boot yotsatira stage pogwiritsa ntchito kutsimikizika kwa ogwiritsa ntchito / decryption algorithm.
Ngati masamba otsimikizika kapena obisika agwiritsidwa ntchito ndiye kuti kiyi yomweyo ya USK (ndiko kuti,
U_MSS_BOOT_SNVM_USK) iyenera kugwiritsidwa ntchito pamasamba onse ovomerezeka/obisika.
Ngati kutsimikizika sikulephera, MSS Core Complex ikhoza kukhazikitsidwanso ndi BOOT_FAIL t.ampmbendera yake ikhoza kukwezedwa. Njirayi ikugwiritsidwa ntchito pogwiritsa ntchito U_MSS_BOOTMODE=2 boot option.

Factory Secure Boot
Munjira iyi, woyang'anira dongosolo amawerenga Satifiketi Yotetezedwa ya Boot Image (SBIC) kuchokera ku eNVM ndikutsimikizira SBIC. Mukatsimikizira bwino, System Controller imakopera code code yotetezedwa ya fakitale kuchokera kumalo ake achinsinsi, otetezedwa ndikuyiyika mu DTIM ya E51 Monitor core. Boot yotetezedwa yosasinthika imayang'ana siginecha pa chithunzi cha eNVM pogwiritsa ntchito SBIC yomwe imasungidwa mu eNVM. Ngati palibe zolakwika zomwe zanenedwa, kukonzanso kumatulutsidwa ku MSS Core Complex. Ngati zolakwika zanenedwa, MSS Core Complex imayikidwa poyambiranso ndipo BOOT_FAIL tampmbendera yake yakwezedwa. Kenako, woyang'anira dongosolo amatsegula paamper mbendera yomwe imawonetsa chizindikiro ku nsalu ya FPGA kuti agwiritse ntchito. Njirayi ikugwiritsidwa ntchito pogwiritsa ntchito U_MSS_BOOTMODE=3 boot option.
SBIC ili ndi adilesi, kukula, hashi, ndi Elliptic Curve Digital Signature Algorithm (ECDSA) siginecha ya bambala wotetezedwa. ECDSA imapereka mtundu wina wa Digital Signature Algorithm yomwe imagwiritsa ntchito elliptic curve cryptography. Ilinso ndi vekitala yobwezeretsanso pa Hardware iliyonse
