Ibhuloho le-HPMS DDR yibhuloho ledatha eliphakathi kwabaphathi bamabhasi abane be-AHB kanye nesigqila sebhasi ye-AXI eyodwa. Iqoqa i-AHB ibhala ekubhaleni okuhlanganisa amabhafa ngaphambi kokuqhuma kumemori ye-DDR yangaphandle. Kuhlanganisa futhi ukufunda okuhlanganisa amabhafa, okuvumela izingcweti ze-AHB ukuthi zifunde kahle idatha evela kumemori yangaphandle ye-DDR evela kusigcinalwazi sasendaweni. Ibhuloho le-DDR lilungiselela ukufunda nokubhala kusuka kumakhosi amaningi kuya kumemori eyodwa ye-DDR yangaphandle. Imithetho yokuhambisana kwedatha phakathi kwezingcweti ezine kanye nenkumbulo ye-DDR yangaphandle isetshenziswa kuhadiwe.
Ibhuloho le-DDR liqukethe amabhafa amathathu okubhala / afundwayo kanye nebhafa eyodwa yokufunda. Wonke amabhafa angaphakathi kwebhuloho le-DDR asetshenziswa ngamaletshi futhi awekho ngaphansi kokuphazamiseka komcimbi owodwa (ama-SEU) aboniswa yi-SRAM. Ukuze uthole imininingwane ephelele sicela ubheke Umhlahlandlela Womsebenzisi we-Microsemi IGLOO2.

Bhala ibhafa Isikhathi Sokuphuma Kwekhawunta

Lesi isixhumi esibonakalayo se-10-bit timer esisetshenziselwa ukulungisa irejista yesikhathi sokuvala kumojuli yebhafa yokubhala (Umfanekiso 1). Uma isibali sikhathi sifinyelela inani lesikhathi sokuvala, isicelo sokuguquguquka senziwa isilawuli se-flush futhi uma impendulo yamukelwe ngesicelo sokubhala sangaphambilini esivela kumxazululi wokubhala, lesi sicelo sithunyelwa kumxazululi wokubhala. Le rejista ijwayelekile kuwo wonke amabhafa.

• Usayizi Wesifunda Ongabhubhisi - Sebenzisa le nketho ukuze usethe usayizi wesifunda sekheli elingabhufa.
• Ikheli Lesifunda Elingapheki (Amabhithi ayi-16 aphezulu)- Sebenzisa le nketho ukuze usethe ikheli eliyisisekelo lendawo yekheli elingagcineki kubhafa. Amabhithi [15:(N – 1)] ale siginali aqhathaniswa nekheli le-AHB [31:(N + 15)] ukuze kuhlolwe ukuthi ingabe ikheli lisesifundeni esingabhafa. Inani lika-N lincike kusayizi wesifunda ongashintsheki, ngakho-ke ikheli lesisekelo lichazwa ngokuvumelana nerejista ye-DDRB_NB_SZ ephethe inani lesifunda elingashintshiseki elichazwe kulesi silungisi.
• Nika amandla ukubhala okuhlanganisa ibhafa - Sebenzisa lezi zinketho ukuze unike amandla ama-Write Combining Buffers we-HPDMA kanye ne-AHB Bus (SWITCH) Masters.
• DDR Burst Usayizi Wokufunda/Bhala Amabhafa - Sebenzisa lokhu ukuze ulungiselele isigcinalwazi sokubhala futhi ufunde usayizi webhafa njengosayizi wokuqhuma kwe-DDR. Amabhafa angalungiselelwa abe ngusayizi we-16-byte noma 32-byte.

Ukwesekwa Komkhiqizo

I-Microsemi SoC Products Group isekela imikhiqizo yayo ngezinsizakalo ezehlukene zokusekela, okuhlanganisa Isevisi Yamakhasimende, Isikhungo Sokusekela Ubuchwepheshe Bamakhasimende, a webindawo, i-imeyili, kanye namahhovisi okuthengisa emhlabeni wonke. Lesi sithasiselo siqukethe ulwazi mayelana nokuxhumana ne-Microsemi SoC Products Group nokusebenzisa lezi zinsizakalo zokusekela.

Insizakalo yekhasimende

Xhumana Nesevisi Yekhasimende ukuze uthole ukwesekwa kwemikhiqizo okungeyona eyobuchwepheshe, njengentengo yomkhiqizo, ukuthuthukiswa komkhiqizo, ulwazi lokubuyekeza, isimo soku-oda, nokugunyazwa.
