Bu yaz\u0131da verilog ile SRAM denetimi konusuna de\u011finece\u011fiz. Asl\u0131nda yap\u0131lmas\u0131 gereken \u00e7ok fazla bir\u015fey yok, SRAM<\/em>lerin aray\u00fczleri ve kullan\u0131mlar\u0131 gayet basit.<\/p>\n

2-SRAM Nedir, Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/strong><\/p>\n

Bu konuda Vikipedi\u2019de \u00e7ok g\u00fczel bir yaz\u0131 var. Tavsiye ederim:<\/p>\n

http:\/\/tr.wikipedia.org\/wiki\/SRAM <\/a><\/p>\n

Bu uygulamada yapmak istedi\u011fimiz belle\u011fin 0 – 5000 adresleri aras\u0131na 8 bitlik artan veri yazmak ve ard\u0131ndan da saniyede bir kere ilk adresten ba\u015flayarak yazd\u0131\u011f\u0131m\u0131z veriyi bellekten okumak.<\/p>\n

SRAM fiziki olarak deneme kart\u0131n\u0131zda bulunmasa bile SRAM\u2019i FPGA i\u00e7inde olu\u015fturup kullanabilirsiniz. Xilinx\u2019de bu Block RAM olarak ge\u00e7iyor. Altera\u2019da ise direk olarak RAM ad\u0131 verilmi\u015f. Ben de bu yaz\u0131da Spartan 3E500 Starter Kit kart\u0131m\u0131 kulland\u0131\u011f\u0131mdan fiziki SRAM yerine Block RAM kullanaca\u011f\u0131m. Block RAM\u2019in nas\u0131l olu\u015fturuldu\u011funa Xilinx Core Generator ile Block RAM olu\u015fturmak<\/a> adl\u0131 yaz\u0131mdan bakabilirsiniz.<\/p>\n

      \u00c7ok g\u00fczel evet BRAM denetledi\u011finizi sand\u0131n\u0131z ama\u2026 acaba cidden denetlediniz mi? Hay\u0131r! Block RAM\u2019i ISE ka\u00e7\u0131rd\u0131 \ud83d\ude00<\/p>\n

      Xilinx ISE otomatik olarak yapt\u0131klar\u0131n\u0131z\u0131 sildi ve saya\u00e7lar yerle\u015ftirdi -\u00e7\u00fcnk\u00fc mant\u0131kl\u0131 olan bu, ama bazen mant\u0131ks\u0131z olarak da silebiliyor, dikkat edin-. Yani Block RAM kullan\u0131lmad\u0131. Hmm\u2026 peki bunu nas\u0131l m\u0131 anlar\u0131z? Bir s\u00fcredir ISE kullan\u0131yorsan\u0131z zaten yeterince \u015f\u00fcphecisinizdir ama de\u011filseniz RTL \u015femas\u0131na bakman\u0131z yeterli:<\/p>\n
