VHDLwhiz Binary File Maphukusi Olemba Owerenga

Chikalatachi chikufotokoza momwe mungagwiritsire ntchito binary ya VHDLwhiz file owerenga ndi wolemba VHDL zoyeserera zomwe zimagwira ma vector autali uliwonse.

Chilolezo

Layisensi ya MIT imakhudza zofunikira za kukopera kwa gwero ndi momwe mungagwiritsire ntchito.

Zosinthazi zikulozera ku polojekiti files, ndipo chikalatachi chikusinthidwa moyenera.

Kufotokozera

Pulojekitiyi ili ndi mapaketi awiri a VHDL owerengera kuchokera kapena kulemba binary kupita files mu kayeseleledwe.

Mitundu yatsopano yotetezedwa ya phukusi (makalasi a VHDL) imapereka mawonekedwe owongoka kwambiri file kupeza kuposa phukusi wamba la TEXTIO la VHDL. Kuphatikiza apo, imalola kuwerenga ndi kulemba kosavuta kwa magawo a data okhala ndi utali wokhazikika.

Ndizothandiza pamabenchi oyesera omwe akugwira ntchito pa binary files komwe magawo azidziwitso sakukwanira malire a byte, mwachitsanzoample, chithunzi files kapena mapaketi a netiweki.

Exampndikugwiritsa ntchito

Ndemanga pamwamba pa njira prototype code mu VHDL files akufotokoza momwe njira ndi ntchito zamitundu yotetezedwa zimagwirira ntchito.

Phunzirani testbench ya VHDL kuti muwone yemwe akugwira ntchitoample yomwe imalemba ndikuwerenganso deta kuchokera ku binary files, ndi review examples pansipa kuti muwone momwe ma vector olembera aatali osiyanasiyana amakhudzira ma byte osungidwa files.

Kulemba ma vector aatali osiyanasiyana

Kumbali inayi, kulemba ma vectors osiyanasiyana kutalika kwa file ndizovuta ndi TEXTIO, koma sizosiyana ndi kulemba ma byte okhala ndi mapaketi a VHDLwhiz.

Mu exampM'munsimu, timalemba kaye vekitala ya 12-bit, kenako pang'ono, ndipo pomaliza, vekitala ya 12-bit kachiwiri file. Chithunzi chomwe chili pansipa chikuwonetsa momwe chidziwitsocho chimasungidwira pazotulutsa file.

Dziwani kuti byte yomaliza ili ndi zero-padded chifukwa zolembazo sizinadzaze.

Kuwerenga ndikosiyana kwenikweni komwe kumamanganso deta ndikutaya zotchingira zilizonse.

Kutengera kapangidwe kake

Pali testbench yodziyesa yokha mu Zip file (testbench.vhd). VHDL testbench iyenera kugwira ntchito mu sewero lililonse la VHDL lothandizira kukonzanso kwathunthu kwa 2008 VHDL, koma run.do script imagwira ntchito mu ModelSim/Questa. Kuti muyendetse testbench, tsegulani ModelSim/Questa ndikulemba choyimira choyeserera:

kuchita /run.do runtb

Nkhani Zodziwika

Endianness ikhoza kusiyana pakati pa machitidwe opangira, simulators, ndi zida zogwiritsira ntchito. Komabe, phukusi la owerenga liyenera kukonzanso zomwe zidapangidwa ndi phukusi la wolemba pamakonzedwe omwewo.
Phukusili ndi losasunthika ndipo limangogwiritsidwa ntchito mu testbenches/simulation.
