Ibhulorho ye-HPMS DDR yibhulorho yedatha phakathi kweenkosi ezine ze-AHB zebhasi kunye nekhoboka elinye lebhasi ye-AXI. Iqokelela i-AHB ibhala ngokudibanisa ii-buffers phambi kokugqabhuka kwimemori yangaphandle ye-DDR. Kukwabandakanya ukufunda ukudibanisa ii-buffers, ukwenza iinkosi ze-AHB ukuba zifunde ngokufanelekileyo idatha evela kwimemori yangaphandle ye-DDR evela kwi-buffer yendawo. Ibhulorho ye-DDR ikhulisa ukufunda nokubhala ukusuka kwiinkosi ezininzi ukuya kwimemori yangaphandle ye-DDR. Imithetho yokubambisana kwedatha phakathi kweenkosi ezine kunye nememori yangaphandle ye-DDR iphunyezwa kwi-hardware.
Ibhulorho ye-DDR iqulethe ukudibanisa okuthathu kokubhala / Funda ii-buffers kunye ne-buffer yokufunda enye. Zonke izithinteli ngaphakathi kwebhulorho ye-DDR ziphunyezwa ngeentambo kwaye azikho phantsi kokuphazamiseka kwesiganeko esinye (se-SEU) esiboniswa yi-SRAM. Ukufumana iinkcukacha ezipheleleyo nceda ubhekisele kwiSikhokelo soMsebenzisi weMicrosemi IGLOO2.

Bhala isithinteli Ixesha lokuphuma kwikhawuntara

Olu lujongano lwe-10-bit timer olusetyenziselwa ukuqwalasela irejista yexesha lokuphuma kwimodyuli yesithinteli sokubhala (Umfanekiso 1). Nje ukuba isibali-xesha sifikelele kwixabiso lexesha lokuvala, isicelo sokugungxulwa senziwa ngumlawuli wokugungxula kwaye ukuba impendulo ifunyenwe kwisicelo sokubhala sangaphambili esivela kumlamli wokubhala, esi sicelo sithunyelwa kwi-arbiter yokubhala. Le rejista iqhelekile kuzo zonke izithinteli.

• Ubungakanani boMmandla obungaBufferable - Sebenzisa olu khetho ukuseta ubungakanani bommandla weedilesi ongena-bufferable.
• Idilesi yoMmandla eNgasetyenziswayo (amasuntswana ali-16)- Sebenzisa olu khetho ukuseta idilesi yesiseko yommandla wedilesi ongagungqiyo. Amasuntswana [15:(N – 1)] alo mqondiso athelekiswa nedilesi ye-AHB [31:(N + 15)] ukujonga ukuba ingaba idilesi ikwingingqi engena-bufferable. Ixabiso lika-N lixhomekeke kubungakanani bommandla obunga-bufferable, ngoko ke idilesi yesiseko ichazwa ngokwe-DDRB_NB_SZ irejista ebambe ubungakanani bommandla obunga-bufferable obuchazwe kulo configurator.
• Yenza uBhalo oluDibanisa i-Buffer -Sebenzisa ezi zikhetho ukwenza ukuba uBhala ngokudibanisa iiBuffers zeHPDMA kunye ne-AHB Bus (SWITCH) Masters.
• DDR Burst Ubungakanani bokufunda/Bhala izithinteli -Sebenzisa oku ukuqwalasela isithinteli sokubhala kwaye ufunde ubungakanani be-buffer ngokwesayizi ye-DDR. Izithinteli zinokumiselwa ukuba zibe yi-16-byte okanye i-32-byte ubukhulu.
