Microsemi IGLOO2 HPMS DDR Controller Configuration
Selelekela
IGLOO2 HPMS e na le molaoli oa DDR o kentsoeng (HPMS DDR). Taolo ena ea DDR e reretsoe ho laola memori ea off-chip DDR. Selaoli sa HPMS DDR se ka fumaneha ho tsoa ho HPMS (ho sebelisa HPDMA) hammoho le lesela la FPGA.
Ha o sebelisa System Builder ho aha block block e kenyelletsang HPMS DDR, System Builder e u etsetsa molaoli oa HPMS DDR ho latela likenyo le likhetho tsa hau.
Ha ho tlhophiso e arohaneng ea HPMS DDR ke mosebelisi e hlokahalang. Ho fumana lintlha, ka kopo sheba Tataiso ea Mosebelisi ea Sehahi sa Sisteme ea IGLOO2.

- Leqepheng la Likarolo tsa Sesebelisoa sa Sehahi sa Tsamaiso, sheba HPMS External DDR Memory (HPMS DDR).
- Ho "Memory" tab, khetha mofuta oa memori ea DDR:
- DDR2
- DDR3
- LPDDR
- Khetha Bophara ba DDR Memori: 8, 16 kapa 32
- Sheba ECC haeba u batla ho ba le ECC bakeng sa DDR.
- Kenya nako ea ho seta memori ea DDR. Ena ke nako eo memori ea DDR e hlokang ho qala.
- Tobetsa Setlhophiso sa Ngoliso ea kantle ho naha ho kenya boleng ba Ngoliso bakeng sa FDDR ho tsoa mongolong o teng file e nang le boleng ba rejisetara. Sheba Lethathamo la 1 bakeng sa tlhophiso ea ngoliso file syntax.
Libero e boloka data ena ea tlhophiso ka bo eona ho eNVM. Ha FPGA e seta bocha, data ena ea tlhophiso e tla kopitsoa ka bo eona ho HPMS DDR.

HPMS DDR Controller Configuration
Ha o sebelisa HPMS DDR Controller ho fihlella DDR Memory e kantle, DDR Controller e tlameha ho qalisoa ka nako ea ts'ebetso. Sena se etsoa ka ho ngola lintlha tsa tlhophiso ho lirejistara tse inehetseng tsa DDR controller. Ho IGLOO2, eNVM e boloka data ea tlhophiso ea ngoliso mme kamora hore FPGA e hlophisoe bocha, data ea tlhophiso e kopitsoa ho tloha ho eNVM ho ea ho lirejisetara tse inehetseng tsa HPMS DDR bakeng sa ho qala.

HPMS DDR Controller e na le lethathamo la lirejistara tse hlokang ho hlophisoa ka nako ea ts'ebetso. Maemo a tlhophiso a lirekoto tsena a emela liparamente tse fapaneng, joalo ka DDR mode, bophara ba PHY, mokhoa oa ho phatloha, le ECC. Bakeng sa lintlha tse felletseng mabapi le lirejistara tsa tlhophiso ea taolo ea DDR ka kopo sheba Tataiso ea mosebelisi ea Microsemi IGLOO2
HPMS MDDR Tlhophiso ea Ngoliso
Ho hlakisa boleng ba Ngoliso ea DDR:
- Sebelisa mohlophisi oa mongolo kantle ho Libero SoC, lokisetsa mongolo file e nang le mabitso a Ngoliso le litekanyetso, joalo ka setšoantšong sa 1-1.
- Ho tsoa ho tab ea Memori ea Sehahi sa Sistimi, tlanya Tokiso ea Registering ea ho Kenya.
- Tsamaea sebakeng sa mongolo oa Tlhophiso ea Ngoliso file u se lokiselitse ho Mohato oa 1 ebe u khetha file ho kenya.
