Tlhophiso le Khokahano

SmartFusion Microcontroller Subsystem e u thusa ho holisa AMBA Bus lesela la FPGA ka tlhaho. U ka hlophisa sebopeho sa masela sa AMBA joalo ka APB3 kapa AHBLite ho latela litlhoko tsa moralo oa hau. Sehokelo sa libese tsa master le makhoba se fumaneha ka mokhoa o mong le o mong.
Tokomane ena e fana ka mehato ea bohlokoa ea ho theha sistimi e tsoakiloeng ea lesela la MSS-FPGA AMBA AHBLite/APB3 ho sebelisoa setlhophiso sa MSS se fumanehang ho software ea Libero® IDE.
Lisebelisoa tsa AHBLite li hoketsoe ho MSS ho sebelisoa CoreAHBLite mofuta 3.0.112 kapa ho feta.
Lisebelisoa tsa APB li hoketsoe ho MSS ho sebelisoa CoreAPB3 mofuta oa 3.0.101 kapa ho feta.
CoreAHBLite le CoreAPB3 li-cores li kopanngoa ho sebelisoa CoreAHBtoAPB3 mofuta oa 2.0.114 kapa ho feta.
Bakeng sa lintlha tse ling mabapi le Fabric Interface Controller (FIC), ka kopo sheba Tataiso ea mosebelisi ea Actel SmartFusion Microcontroller Subsystem.

MSS Configuration

Mohato oa 1. Khetha MSS FCLK (GLA0) ho lesela la tekanyo ea oache.
Khetha FAB_CLK karohano ho MSS Clock Management Configurator joalokaha ho bontšitsoe setšoantšo sa 1-1. U tlameha ho etsa tlhahlobo ea nako ea morao-rao ea static ho netefatsa hore moralo o kopana le litlhoko tsa nako tse hlalositsoeng ho Clock Management Configurator. U kanna ua tlameha ho lokisa karolelano ea oache lipakeng tsa MSS le lesela ho fumana moralo o sebetsang.

Mohato oa 2. Khetha mokhoa oa MSS AMBA.
Khetha Mofuta oa AHBLite oa Sebopeho ho MSS Fabric Interface Configurator joalokaha ho bontšitsoe setšoantšong sa 1-2.

Mohato oa 3. Khothalletsa boema-kepe bo ka sehloohong ba Masela a AHBLite Bus Interface (BIF) (joalokaha ho bontšitsoe setšoantšong sa 1-3).

• Numella AHBLite Master Bus Interface (BIF) joalo ka ha ho bonts'itsoe ho Setšoantšo sa 1-2.
• Ho setlhophiso sa MSS, tobetsa ka ho le letona boema-kepe ba Bus Interface (MSS Fabric Interface core) ebe u khetha Promoteto-top. Joale boema-kepe ba BIF bo tla fumaneha boemong bo latelang ba bolaoli (moo katoloso ea masela e lokelang ho kengoa ts'ebetsong).

Mohato oa 4. Khothaletsa FAB_CLK ho e etsa boema-kepe (joalokaha ho bontšitsoe setšoantšong sa 1-3).
Ho configurator ea MSS, tobetsa ka ho le letona ho FAB_CLK (MSS Clock Management core) ebe u khetha Hlakola tšobotsi, ebe u e tobetsa ka ho le letona hape ebe u khetha Ntšetsa-ho-holimo. Boema-kepe ba FAB_CLK bo tla fumaneha boemong bo latelang ba bolaoli (moo katoloso ea lesela e lokelang ho kengoa ts'ebetsong).

Hlokomela: Actel e khothaletsa hore o se fetole FAB_CLK lebitso la boema-kepe ba boemo bo holimo. Sesebelisoa sa SmartDesign auto-connect se sebetsa feela haeba lebitso la boema-kepe la FAB_CLK le so fetoloe.

Mohato oa 5. Phahamisa M2F_RESET_N ho e etsa boema-kepe.
Ho setlhophiso sa MSS, tlanya M2F_RESET_N (MSS Reset Management core) ebe u khetha Hlakileng tšobotsi.
Boema-kepe ba M2F_RESET_N bo tla fumaneha boemong bo latelang ba bolaoli (moo katoloso ea lesela e lokelang ho kengoa ts'ebetsong).

Hlokomela: Actel e khothaletsa hore o se fetole M2F_RESET_N lebitso la boema-kepe ba boemo bo holimo. Sesebelisoa sa "autoconnect" sa SmartDesign se sebetsa feela haeba lebitso la boema-kepe la M2F_RESET_N le so fetoloe.

Theha FPGA Fabric le AMBA Subsystem

The subsystem AMBA ea lesela e entsoe ka karolo e tloaelehileng ea SmartDesign, ebe karolo ea MSS e kenngoa ka har'a karolo eo (joalokaha ho bontšitsoe setšoantšong 1-4).

Mohato oa 1. Kenya le ho lokisa CoreAHBLite.

• Kgetha Mokgwa wa Memori 1 jwaloka ha ho bontshitswe ho Figure 1-4. Mokhoa ona o fana ka 15 64KB slots e ka sebelisoang ho hokahanya makhoba a 15 AHBLite. U ka iphapanyetsa li-slots tsa bareki ba 16 4KB (tse kentsoeng ho Slot 4) le sekotjana se seholo kaha ha li na thuso ho tlhophiso ena ea MSS.
• Lumella libaka tseo u rerang ho li sebelisa molemong oa hau. Numella li-slots ho tsoa ho ENABLE Master1 AHBLite Slave Slots sehlopha joalo ka ha ho bonts'itsoe setšoantšong se ka tlase. Ke li-slots tse 5 ho isa ho tse 15 feela tse ka sebelisoang ha CoreAHBLite e hokahane le karolo ea MSS. Sheba “Khomphutha ea Memori” leqepheng la 13.

Mohato oa 2. Kenya Core AHB ho APB3
Mohato oa 3. Kenya le ho lokisa CoreAPB3

• Khetha mokhoa oa ho bua ka kotloloho.
• Khetha bophara ba libese tsa 32-bit APB tse ka sehloohong tsa libese. Ke bophara ba bophara ba bese ea data ea MSS AMBA.
• Tlosa li-slots tseo u sa rerang ho li sebelisa bakeng sa ts'ebeliso ea hau. Li-slots tsohle lia fumaneha. Sheba "Memory Map Computation" leqepheng la 13 bakeng sa lintlha tse ling mabapi le boholo ba slot le khokahanyo ea makhoba/slot.
• Khetha boholo ba sekotjana sa APB joalo ka 4KB kapa ka tlase joalo ka ha ho bonts'itsoe ho Setšoantšo sa 1-5. Ha re nka hore u khethile 64KB slots sizes for CoreAHBLite, joale boholo ba boholo ba slot ho CoreAPB3 (16 slots) ke 64KB/16 = 4KB ha u feta CoreAHBtoAPB3.

Mohato oa 5. Kenya 'me u hlophise lisebelisoa tsa AMBA AHBLite le APB moralong oa hau.
Mohato oa 6. Kopanya subsystem hammoho. Sena se ka etsoa ka bohona kapa ka letsoho.

Khokahano e Ikemetseng - Sesebelisoa sa SmartDesign auto-connect (e fumanehang ho SmartDesign Menu, toolbar kapa ka ho tobetsa ka ho le letona ho Canvas) e tla hokahanya lioache tsa tsamaiso ea tsamaiso le ho li hlophisa bocha ebe li u hlahisa ka mohlophisi oa 'mapa oa memori moo o ka abelang makhoba a AHBLite le APB liaterese tse nepahetseng. Hlokomela hore karolo ea Auto-Connect e etsa oache le ho seta likhokahano bocha ha feela mabitso a boema-kepe a FAB_CLK le M2F_RESET_N a so fetoloe karolong ea MSS.

Tlhophiso le Khokahano

Khokahano ka letsoho- Hokela subsystem ka tsela e latelang:

• Hokela CoreAHBLite seipone-master BIF M0 kapa M1 ho MSS Master BIF (joalokaha ho bontšitsoe setšoantšong 1-8). Sebelisa M1 haeba u rera ho theha tsamaiso e nyenyane ea li-multi-master moo u nang le mong'a lesela le hlokang tšobotsi ea remap 'me kahoo e hloka ho hokahanngoa le M0.
• Hokela BIF ea lekhoba la CoreAHBtoAPB3 le BIF ea seipone ea lekhoba la CoreAHBLite.
• Hokela CoreAPB3 e nang le seipone-master BIF ho MSS master BIF.
• Hokela makhoba a APB le AHBLite libakeng tse loketseng ho latela lintlha tsa 'mapa oa memori.
• Hokela FAB_CLK ho HCLK/PCLK ea lisebelisoa tsohle tsa AHBLite/APB moralong oa hau.
• Hokela M2F_RESET_N ho HRESET/PRESET ea lisebelisoa tsohle tsa AHBLite/APB moralong oa hau.

Memori Map Computation

Foromo e Akaretsang
Bakeng sa AHBLite, boholo ba slot bo lula bo le 64KB slots = 65536 slots (0x10000).

Bakeng sa sebaka se seng le se seng sa AHBLite sa 5 ho isa ho 15 (slots 0 ho isa ho 4 e thibetsoe ho latela 'mapa oa memori oa CortexM3), aterese ea peripheral ea moreki ke:
0x40000000 + (nomoro ea slot ea AHBLite * 0x10000).

Bakeng sa sebaka se seng le se seng sa APB3 (lits'oants'o tsohle li teng), aterese ea peripheral ea moreki ke:
0x40000000 + (nomoro ea sekotjana sa AHBLite * 0x10000) + (nomoro ea sekotjana sa APB3 * boholo ba sekotjana sa APB3).

Hlokomela: Aterese ea motheo ea lesela e tsitsitse ho 0x4005000, empa ho nolofatsa 'mapa oa memori re bonts'a aterese ea motheo e le 0x40000000.

'Mapa oa memori View
U ka bona 'mapa oa memori ea sistimi ka ho sebelisa Sets'oants'o sa Memori ea SmartDesign / Data Sheet (ho tsoa ho menu ea SmartDesign ho Libero IDE Project Manager). Bakeng sa mohlalaample, Setšoantšo sa 2-1 ke 'mapa oa memori o hlahisitsoeng bakeng sa tsamaiso e nyenyane e bontšitsoeng ho Figure 1-8 leqepheng la 11.
