Zonke iziqondiso zabasebenzisi be-IP nezincwadi zezandla zitholakala ku-Libero SoC -> Ikhathalogi.

I-RTG4 μPROM igcina amagama angu-10,400 angu-36-bit (374,400 bits of data). Isekela ukusebenza kokufunda kuphela phakathi nokusebenza okujwayelekile kwedivayisi ngemva kokuhlelwa kocingo. I-MIV_RV32_C0 processor core ihlanganisa iyunithi yokulanda imiyalelo, ipayipi lokuqalisa, kanye nesistimu yememori yedatha. Isistimu yememori yephrosesa ye-MIV_RV32_C0 ihlanganisa inqolobane yemiyalelo nenqolobane yedatha. I-MIV_RV32_C0 core ihlanganisa izixhumanisi ezimbili zangaphandle ze-AHB-i-AHB memory master interface (MEM) kanye ne-AHB Memory Mapped I/O (MMIO) master interface. Isilawuli senqolobane sisebenzisa isixhumi esibonakalayo se-AHB MEM ukuze sigcwalise kabusha imiyalelo nezinqolobane zedatha. Isixhumi esibonakalayo se-AHB MMIO sisetshenziselwa ukufinyelela okungagciniwe kuma-peripherals we-I/O.

Amamephu enkumbulo okuxhumana kwe-AHB MMIO kanye nesixhumi esibonakalayo se-MEM kungu-0x60000000 kuya ku-0X6FFFFFFF kanye no-0x80000000 kuya ku-0x8FFFFFF, ngokulandelanayo. Ikheli le-vector lokusetha kabusha lephrosesa liyalungiseka. Ukusetha kabusha kwe-MIV_RV32_C0 kuyisignali esebenzayo-low, okumele igonywe ekuvunyelanisweni newashi lesistimu ngokuvumelanisa kabusha.

Iphrosesa ye-MIV_RV32_C0 ifinyelela inkumbulo yokusebenzisa uhlelo lokusebenza isebenzisa isixhumi esibonakalayo se-AHB MEM. Isenzakalo sebhasi se-CoreAHBLite_C0_0 silungiselelwe ukuhlinzeka ngezikhala zezigqila ezingu-16, ngasinye sinosayizi ongu-1 MB. Imemori ye-RTG μPROM, namabhulokhi e-RTG4FDDRC ​​axhunywe kuleli bhasi. I-μPROM isetshenziselwa ukugcina uhlelo lwe-bootloader.

Iphrosesa ye-MIV_RV32_C0 iqondisa ukuthengiselana kwedatha phakathi kwamakheli 0x60000000 kanye no-0x6FFFFFFF kusixhumi esibonakalayo se-MMIO. Isixhumi esibonakalayo se-MMIO sixhunywe ebhasini le-CoreAHBLite_C1_0 ukuze lixhumane nama-peripheral axhunywe kuzikhala zalo zezigqila. Isenzakalo sebhasi se-CoreAHBLite_C1_0 silungiselelwe ukuhlinzeka ngezikhala zezigqila ezingu-16, ngayinye inosayizi ongu-256 MB. I-UART, CoreSPI, ne-CoreGPIO peripherals ixhunywe ebhasini le-CoreAHBLite_C1_0 ngebhuloho le-CoreAHBTOAPB3 kanye nebhasi le-CoreAPB3.

I-Microsemi ayenzi iwaranti, isethulo, noma isiqinisekiso mayelana nolwazi oluqukethwe lapha noma ukufaneleka kwemikhiqizo nezinsizakalo zayo nganoma iyiphi inhloso, futhi i-Microsemi ayithathi noma yisiphi isikweletu esivela ngenxa yesicelo noma ukusetshenziswa kwanoma yimuphi umkhiqizo noma isifunda. Imikhiqizo ethengiswa lapha ngezansi kanye nanoma yimiphi eminye imikhiqizo ethengiswa yi-Microsemi ibe ngaphansi kokuhlolwa okulinganiselwe futhi akufanele isetshenziswe ngokuhambisana nemishini ebalulekile yemishini noma izinhlelo zokusebenza. Noma yikuphi ukucaciswa kokusebenza kukholakala ukuthi kunokwethenjelwa kodwa akuqinisekisiwe, futhi Umthengi kufanele enze futhi aqedele konke ukusebenza nokunye ukuhlola kwemikhiqizo, iyodwa kanye, noma efakwe kuyo, noma yimiphi imikhiqizo yokugcina. Umthengi ngeke athembele kunoma iyiphi idatha kanye nokucaciswa kokusebenza noma amapharamitha anikezwe i-Microsemi. Kuyisibopho somthengi ukunquma ngokuzimela ukufaneleka kwanoma imiphi imikhiqizo kanye nokuhlola nokuqinisekisa okufanayo. Ulwazi olunikezwe yi-Microsemi lapha ngezansi lunikezwa "njengoba lukhona, lukuphi" futhi nawo wonke amaphutha, futhi yonke ingozi ehlobene nolwazi olunjalo iphelele kuMthengi. I-Microsemi ayinikezi, ngokusobala noma ngokungagunci, kunoma iyiphi inhlangano noma yimaphi amalungelo obunikazi, amalayisense, nanoma imaphi amanye amalungelo e-IP, kungakhathaliseki ukuthi ngokuphathelene nalolo lwazi ngokwalo noma noma yini echazwe ulwazi olunjalo. Ulwazi olunikezwe kulo mbhalo luphathelene ne-Microsemi, futhi i-Microsemi inelungelo lokwenza noma yiziphi izinguquko kulwazi olukulo mbhalo noma kunoma yimiphi imikhiqizo namasevisi nganoma yisiphi isikhathi ngaphandle kwesaziso.
