Mlatho wa HPMS DDR ndi mlatho wa data pakati pa ambuye anayi a mabasi a AHB ndi kapolo mmodzi wa basi ya AXI. Imaunjikira AHB kuti ilembe ndikuphatikiza ma buffers isanadutse kukumbukira kwa DDR. Zimaphatikizansopo kuwerenga kuphatikiza ma buffers, kupangitsa masters a AHB kuti awerenge bwino deta kuchokera kumakumbukiro akunja a DDR kuchokera ku buffer yakomweko. Mlatho wa DDR umakulitsa kuwerenga ndikulemba kuchokera ku masters angapo kupita ku memory imodzi yakunja ya DDR. Malamulo ogwirizana ndi data pakati pa ambuye anayi ndi kukumbukira kwakunja kwa DDR amayendetsedwa mu hardware.
Mlatho wa DDR uli ndi zolemba zitatu zophatikiza / Werengani ma buffers ndi buffer imodzi yowerengera. Zosungira zonse zomwe zili mkati mwa mlatho wa DDR zimayikidwa ndi zingwe ndipo sizimakhudzidwa ndi zochitika zapagulu (SEU's) zomwe SRAM imawonetsa. Kuti mudziwe zambiri, chonde onani Maupangiri Ogwiritsa Ntchito a Microsemi IGLOO2.

Lembani Buffer Time Out Counter

Uwu ndi mawonekedwe a 10-bit timer omwe amagwiritsidwa ntchito kukonza zolembera zanthawi yomaliza mu gawo lolemba la buffer (Chithunzi 1). Nthawi yowerengera ikafika pamtengo wanthawi yake, pempho la flush limapangidwa ndi wowongolera ndipo ngati yankho lalandilidwa pa pempho lolemba kale kuchokera kwa wolemba arbiter, pempholi limatumizidwa kwa wolemba arbiter. Regista iyi ndi yofala pama buffer onse.

• Kukula kwa Dera Losatheka - Gwiritsani ntchito njirayi kuti muyike kukula kwa ma adilesi omwe sangasungidwe.
• Adilesi Yachigawo Yosasinthika (Pamwamba pa 16 bits)- Gwiritsani ntchito njirayi kuti mukhazikitse ma adilesi oyambira omwe sangasungidwe mabanki. Bits [15:(N – 1)] ya siginoyi imayerekezedwa ndi adilesi ya AHB [31:(N + 15)] kuti muwone ngati adilesi ili mdera lomwe silingathe kusinthidwa. Mtengo wa N umadalira kukula kwa chigawo chosasinthika, kotero adilesi yoyambira imatanthauzidwa molingana ndi regista ya DDRB_NB_SZ yomwe imakhala ndi mtengo wachigawo wosasunthika womwe umafotokozedwa mu kasinthidwe.
• Yambitsani Kulemba Kuphatikiza Buffer - Gwiritsani ntchito izi kuti muthe Kulemba Kuphatikiza Ma Buffers a HPDMA ndi AHB Bus (SWITCH) Masters.
• DDR Burst Kukula Kwa Kuwerenga / Kulemba Ma Buffers - Gwiritsani ntchito izi kukonza buffer ndikuwerenga kukula kwa buffer malinga ndi kukula kwa DDR. Ma buffers amatha kusinthidwa kukhala 16-byte kapena 32-byte kukula.

Customer Technical Support Center

Gulu la Microsemi SoC Products Group limagwiritsa ntchito Customer Technical Support Center yokhala ndi mainjiniya aluso kwambiri omwe angakuthandizeni kuyankha ma hardware anu, mapulogalamu, ndi mafunso apangidwe okhudza Microsemi SoC Products. Customer Technical Support Center imathera nthawi yochuluka kupanga zolemba zofunsira, mayankho ku mafunso wamba ozungulira, zolemba zankhani zodziwika, ndi ma FAQ osiyanasiyana. Chifukwa chake, musanalankhule nafe, chonde pitani pazathu zapaintaneti. Ndizotheka kuti tayankha kale mafunso anu.
