現在開発中のNANDのみを用いたCPUのプロジェクトです．
現在以下のバリエーションが存在します
- NLP-16
- NLP-16A
NLP-16は本プロジェクトの最初の成果物です．2019年(私が高校2年)の冬に設計を開始し，そこから３年ほどかけ製作しました．
動作(Twitter)
単独での動作に成功しましたがいくつかの改善点が見つかったため，NLP-16によって得られた知見を基に改良版としてNLP-16Aを現在は開発中です．
また，NLP-16Aではキット化を目標に設計，製作しています．

Questions
How big is the Alu c PCB?
It measures 209.5 × 154.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alu c use?
174 parts, built around the CD74HC00M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Alu c KiCad files?
From the cherry-takuan/nlp repository on GitHub, at the commit this page was made from: the board is nlp-16a/Hardware/alu_c/alu_c.kicad_pcb and its schematic nlp-16a/Hardware/A_BUS_Ctrl/A_BUS_Ctrl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alu c design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
