SmartFusion Microcontroller Subsystem AHB Bus Matrix ndi yosinthika kwambiri.
Kukonzekera kwa MSS AHB Bus Matrix kumakupatsani mwayi wofotokozera magawo ang'onoang'ono a masanjidwe a mabasi. Zosankha zomwe zafotokozedwa mu configurator zikhoza kukhala zosasunthika pa ntchito yomwe yapatsidwa ndipo - ikayikidwa mu configurator - idzasinthidwa zokha mu chipangizo cha SmartFusion ndi Actel System Boot. Zosankha zina zosinthika monga eNVM ndi eSRAM remapping ndizotheka kukhala masinthidwe anthawi-nthawi ndipo sizipezeka mu kasinthidwe aka.
M'chikalata ichi tikupereka kufotokoza mwachidule za zosankhazi. Kuti mumve zambiri chonde onani za Actel SmartFusion Microcontroller Subsystem User's Guide.

Kuthetsa
Kapolo Arbitration Algorithm. Iliyonse mwa mawonekedwe a akapolo ili ndi arbiter. The arbiter ali ndi njira ziwiri zogwirira ntchito: (woyera) robin yozungulira ndi robin yolemera (monga momwe tawonetsera pa Chithunzi 1). Dongosolo lokhazikika lomwe lasankhidwa limagwiritsidwa ntchito pazolumikizana zonse za akapolo. Zindikirani kuti wogwiritsa ntchitoyo amatha kuwongolera chiwembu chotsutsana mwamphamvu pamakina awo othamanga pa ntchentche.
Chitetezo - Port Access
Aliyense mwa ambuye omwe si a Cortex-M3 olumikizidwa ndi matrix a basi a AHB amatha kutsekedwa kuti asafike pamadoko aliwonse akapolo olumikizidwa ndi matrix a basi. Madoko a Fabric Master, Ethernet MAC ndi Peripheral DMA amatha kutsekedwa poyang'ana bokosi lofananira mu kasinthidwe kameneka. Zindikirani kuti pankhani ya mbuye wa nsalu, mwayi wofikira umayenereranso ndi zosankha zachigawo zoletsedwa zomwe zafotokozedwa pansipa.
Chitetezo - Soft processor Memory Access
Chepetsani Kufikira Kukumbukira
- Kuletsa njirayi kumathandizira purosesa iliyonse yofewa (kapena master master) kuti ipeze malo aliwonse pamapu okumbukira a Cortex-M3.
- Kuthandizira njirayi kumalepheretsa purosesa iliyonse yofewa (kapena master master) kuti ifike pamalo aliwonse pamapu okumbukira a Cortex-M3 ofotokozedwa ndi Restricted Memory Region.
Kukula kwa Dera la Memory - Njira iyi imatanthawuza kukula kwa chigawo choletsedwa cha kukumbukira kwa mbuye wa nsalu.
Adilesi Yachigawo cha Memory Yoletsedwa - Njira iyi imatanthawuza adilesi yoyambira ya memory yoletsedwa. Adilesi iyi iyenera kulumikizidwa ndi kukula kwa dera lomwe lasankhidwa.

Kufotokozera kwa Port
Table 1 • Cortex-M3 Port Description
| Dzina la Port | Mayendedwe | PAD? | Kufotokozera |
| Mtengo wa RXEV | IN | Ayi | Imayambitsa Cortex-M3 kudzuka kuchokera ku malangizo a WFE (kuyembekezera chochitika). Zomwe zachitika, RXEV, zimalembetsedwa ngakhale osadikirira chochitika, ndipo zimakhudza WFE yotsatira. |
| Mtengo wa TXEV | OUT | Ayi | Chochitika chofalitsidwa chifukwa cha malangizo a Cortex-M3 SEV (tumizani chochitika). Uku ndi kugunda kwapang'onopang'ono kofanana ndi nthawi ya 1 FCLK. |
| GONA | OUT | Ayi | Chizindikirochi chimatsimikiziridwa pamene Cortex-M3 ili m'tulo tsopano kapena njira yogona-potuluka, ndikuwonetsa kuti wotchi yopita ku purosesa ikhoza kuyimitsidwa. |
| TULO LOYAMBA | OUT | Ayi | Chizindikirochi chimatsimikiziridwa pamene Cortex-M3 ili m'tulo tsopano kapena njira yogona-potuluka pamene SLEEPDEEP pang'ono pa System Control Register yakhazikitsidwa. |

Gulu la Microsemi SoC Products limathandizira zogulitsa zake ndi ntchito zosiyanasiyana zothandizira kuphatikiza Customer Technical Support Center ndi Non-Technical Customer Service. Zowonjezerazi zili ndi zambiri zokhudzana ndi kulumikizana ndi SoC Products Group ndikugwiritsa ntchito chithandizochi.
Kulumikizana ndi Customer Technical Support Center
Microsemi imagwiritsa ntchito Customer Technical Support Center yokhala ndi mainjiniya aluso omwe angakuthandizeni kuyankha mafunso anu a hardware, mapulogalamu, ndi kapangidwe kake. Customer Technical Support Center imathera nthawi yochuluka kupanga zolemba ndi mayankho ku FAQs. Chifukwa chake, musanalankhule nafe, chonde pitani pazathu zapaintaneti. Ndizotheka kuti tayankha kale mafunso anu.
Othandizira ukadaulo
Makasitomala a Microsemi atha kulandira chithandizo chaukadaulo pazinthu za Microsemi SoC poyimbira Hotline Yothandizira paukadaulo nthawi iliyonse Lolemba mpaka Lachisanu.
