** systemVerilog UART-16550 [#p4730cd9]
RS-232Cでおなじみのシリアル通信モジュールです。
systemVerilog-IEEE1800-2009で書いてあります。
これでSVの勉強してね。
altera cyclone3
800cellちょうど -> fifoをalt_fifoにすれば450cellぐらいかな
>100MHz
””LGPL条件””で公開します。。バグレポート歓迎。。汗)
このページの末尾に置いておきます。
** DMAC回路 [#p4730cd9]
CPUを介さずにメモリー間のデータ転送を行う回路。
1チャネルで単に転送するだけの回路ですがアップしておきます。
#ref (dmac.v)
** 調停回路 [#p4730cd9]
一つしかない物を多人数で使用するときは調停をする必要が有ります。
代表的な方法に優先権と順番によるものが有ります。
たとえば1本しかない電話を社長が最優先で使用するとか、優先権による調停ですね。
でも知り合いの社長とフィリピンバーのねーちゃんの話だったりして。
回路でも同様に調停回路と言う物が必要なときがありそれぞれ目的に応じて作られています。
ここでは、優先権と順番を切り替えることの出来る3bitの調停回路を公開します。
> たいした物では無いけど、検証とかLSI設計ページの構成上置いておきます。
