Nezve Erasure Decoder Reference Dhizaini

• Iyo Erasure Decoder ndiyo imwe mhando yeReed-Solomon decoder inoshandisa isiribinary, cyclic, linear block kukanganisa kodhi kodhi.
• MuReed-Solomon decoder ine erasure decoding capability, nhamba yezvikanganiso (E) uye erasures (E’) yaunogona kugadzirisa ndeiyi: n – k = 2E + E’
• Iko n ndiko kureba kweblock uye k ndiko kureba kwemeseji (n-k inoenzana nenhamba yezviratidzo zveparity).
• Iyo Erasure Decoder inongotarisa erasures, saka kugona kugadzirisa kunogona kusvika pakakwirira yakapihwa nan-k. Iyo decoder inogamuchira sekuisa nzvimbo dzekudzima, dzinowanzo kupihwa nedemodulator mukati meiyo coding system, iyo inogona kuratidza mamwe akagamuchirwa macode zviratidzo seasina kuvimbika. Iyo dhizaini haifanire kudarika erasure kugadzirisa kugona. Dhizaini inobata zviratidzo izvo zvinoratidza sekudzima sezero kukosha.

Erasure Decoder Inoshanda Tsananguro

• Iyo Erasure Decoder haigadzirise zvikanganiso, inodzima chete. Iyo inodzivirira kuoma kwekutsvaga nzvimbo dzekukanganisa, izvo zvinoda Reed-Solomon decoding.
• Iyo dhizaini algorithm uye zvivakwa zvakasiyana neReed-Solomon decoder. Erasure decoding imhando ye encoding. Inoedza kuzadza iyo inopinza ne p=n-k zviratidzo kuti igadzire codeword inoshanda, nekuzadzisa iwo equations. Iyo parity matrix uye jenareta matrix inotsanangura parity equations.
• Iyo dhizaini inoshanda chete nediki Reed-Solomon macode, akadai seRS(14,10), RS(16,12), RS(12,8) kana RS(10,6). Kune nhamba shoma yezviratidzo zveparity (p k-p), unofanira kushandisa jenareta matrix.
• Iyo erasure pateni (inomiririrwa ne-n-bits wide in_era input) inotarisa ROM uko dhizaini inochengeta parity submatrices. Dhizaini ine n p = n! k! n − k ! maitiro ekudzima anokwanisika. Naizvozvo, dhizaini inoshandisa kero yekumanikidza module.
• Dhizaini inoisa kero nenhamba yekero idiki pane kero uye ine chaiyo p bits set.
• Iyo Erasure Decoder inogamuchira pakupinza kwayo chero mwero wezviratidzo zvinopinda, kusvika kune yakazara block urefu n per cycle kune yakanyanya kubuditsa. Iwe unogona kugadzirisa parallelism uye nhamba yezviteshi, kuitira kuti dhizaini iwande zviratidzo zvinouya nenhamba yematanho anoenderana neakaenzana codewords anosvika panguva imwe chete.
• Iyo erasure decoder inogadzira iyo yakazara decoded codeword, kusanganisira cheki zviratidzo, mune imwe kutenderera (anoverengeka macodewords ematanho akati wandei).

Bhafa yekupinda inobvumidza iwe kuve nenhamba yezviratidzo zvakafanana pachiteshi zvishoma pane iyo yakazara block urefu (n). Intel inokurudzira kuti ushandise bandwidth yekupinza, kunze kwekunge kufanana kunoenderana nezvinodiwa zvekushandisa.

Erasure Decoder Interface uye Zviratidzo

• Iyo Avalon-ST interface inotsigira backpressure, inova nzira yekudzora kuyerera, uko kunyura kunogona kuratidza kune sosi kumisa kutumira data.
• Iyo yakagadzirira latency pane iyo Avalon-ST yekuisa interface ndeye 0; nhamba yezviratidzo pabhiti yakamisikidzwa ku1.
• Iyo wachi uye reset interfaces inotyaira kana kugamuchira wachi uye reset chiratidzo kuwiriranisa iyo Avalon-ST interfaces.

Avalon-ST Interfaces muDSP IP Cores

• Avalon-ST interfaces inotsanangura yakajairwa, inochinjika, uye modular protocol yekufambisa data kubva kune sosi interface kuenda kune sink interface.
• Iyo yekupinza interface ndeye Avalon-ST kunyura uye inobuda interface ndeye Avalon-ST sosi. Iyo Avalon-ST interface inotsigira kuchinjirwa kwepaketi nemapaketi akabatanidzwa mumatanho akawanda.
• Masaini eAvalon-ST anogona kutsanangura ma interfaces ekutamba echinyakare anotsigira asinKuyerera kwedata pasina ruzivo rwemigero kana miganhu yemapaketi. Ma interface akadaro anowanzo kuve nedata, masaini akagadzirira, uye anoshanda. Ma interface eAvalon-ST anogonawo kutsigira maprotocol akaomarara ekuputika uye kutamiswa kwemapaketi nemapaketi akapindirana mumachaneli akawanda. Iyo Avalon-ST interface inosanganisa magadzirirwo emachaneli akawanda, izvo zvinokutendera kuti uwane mashandisirwo anoshanda, ane nguva yakawanda pasina kushandisa complex control logic.
• Avalon-ST interfaces inotsigira backpressure, inova nzira yekudzora kuyerera uko singi inogona kuratidza kune sosi kuti irege kutumira data. Iyo sink inowanzo shandisa backpressure kumisa kuyerera kwedata kana mafifo ayo mabhafa azara kana kana aine congestion pakubuda kwayo.

• Chiratidzo chakanzi in_valid chinoratidza data chaiyo.
• Imwe neimwe codeword inogona kusvika pamusoro akati wandei, zvichienderana neparallelism parameter. Iyo dhizaini inoteedzera chimiro chekuisa, saka haidi miganhu yepakiti pane iyo interface. Iyo dhizaini Nhamba yezviteshi mune zvakafanana inowedzera throughput nekudzokorora mayuniti anoshanda kune ese machaneli anowirirana. Iyi dhizaini haishandise Avalon-ST interface yakawanda chiteshi rutsigiro.
• Kana iyo decoder ikataura iyo yekunze_valid chiratidzo, inopa iyo inoshanda data pane out_data.
• Iyo inoburitsa C codewords kutenderera, uko C ndiyo nhamba yematanho anoenderana. Iyo IP musimboti inotaura kunze_kukanganisa chiratidzo kana ichinge yagamuchira isina-yakagadziriswa codeword, kureva: kana iyo IP musimboti ichipfuura erasure kugadzirisa kugona.
