Umlawuli we-cache usebenzisa i-AHB MEM interface ukuze azalise kwakhona imiyalelo kunye nee-cache zedatha. Ujongano lwe-AHB MMIO lusetyenziswa kunikezelo olungagcinwanga kwi-I/O peripherals.

Iimephu zememori ze-AHB MMIO interface kunye ne-MEM interface yi-0x60000000 ukuya ku-0X6FFFFFF kunye ne-0x80000000 ukuya kwi-0x8FFFFFF, ngokulandelanayo. Idilesi yevektha yokusetha ngokutsha yomqhubekekisi iyalungiseka. Ukusetha kwakhona kwe-MIV_RV32_C0 luphawu olusebenzayo-ophantsi, ekufuneka lususwe kungqamaniso ngewotshi yenkqubo ngokusetha kwakhona isingqamanisi.

I-MIV_RV32_C0 iprosesa ifikelela kwimemori yokwenziwa kwesicelo isebenzisa ujongano lwe-AHB MEM. I-CoreAHBLite_C0_0 umzekelo webhasi ibumbeke ukuba ibonelele ngeendawo zokubeka amakhoboka ezili-16, nganye inobungakanani obuyi-1 MB. Imemori ye-RTG μPROM, kunye neebhloko ze-RTG4FDDRC ​​ziqhagamshelwe kule bhasi. I-μPROM isetyenziselwa ukugcina usetyenziso lwe-bootloader.

Iprosesa ye-MIV_RV32_C0 ilawula ukuthengiselana kwedatha phakathi kweedilesi 0x60000000 kunye ne-0x6FFFFFF kwi-interface ye-MMIO. Ujongano lweMMIO luqhagamshelwe kwi-CoreAHBLite_C1_0 ibhasi ukunxibelelana neeperipherals eziqhagamshelwe kwiindawo zokubeka amakhoboka. I-CoreAHBLite_C1_0 ibhasi ilungiselelwe ukunika iindawo zokubeka amakhoboka ali-16, indawo nganye inobukhulu obungama-256 MB. I-UART, CoreSPI, kunye ne-CoreGPIO peripherals ziqhagamshelwe kwi-CoreAHBLite_C1_0 ibhasi nge-CoreAHBTOAPB3 ibhulorho kunye ne-CoreAPB3 yebhasi.

Naziphi na iinkcukacha zokusebenza zikholelwa ukuba zithembekile kodwa aziqinisekiswanga, kwaye uMthengi kufuneka aqhube kwaye azalise yonke imisebenzi kunye nolunye uvavanyo lweemveliso, zodwa kunye kunye, okanye zifakwe kuyo, nayiphi na imveliso yokugqibela. Umthengi akayi kuthembela kuyo nayiphi na idatha kunye neenkcukacha zokusebenza okanye iiparitha ezinikezelwe yi-Microsemi. Luxanduva loMthengi ukuzimela ngokuzimeleyo ukufaneleka kwazo naziphi na iimveliso kunye nokuvavanya nokuqinisekisa okufanayo. Ulwazi olunikezwa yi-Microsemi apha ngezantsi lunikezelwa "njengoko lukhona, luphi" kunye nazo zonke iimpazamo, kwaye yonke ingozi ehambelana nolwazi olunjalo luphelele kuMthengi. I-Microsemi ayinikezeli, ngokucacileyo okanye ngokungafihliyo, nakweliphi na iqela naliphi na ilungelo lobunikazi, iilayisenisi, okanye nawaphi na amanye amalungelo e-IP, nokuba ngokubhekiselele kulwazi olunjalo ngokwalo okanye nayiphi na into echazwe ngolo lwazi. Ulwazi olunikezwe kolu xwebhu lunelungelo kwi-Microsemi, kwaye i-Microsemi inelungelo lokwenza naluphi na utshintsho kulwazi olukule ncwadana okanye kuyo nayiphi na imveliso kunye neenkonzo nangaliphi na ixesha ngaphandle kwesaziso.
