Overlay GHC - Tutorial 1

   Circuit Fellow.

This is a tutorial by which you can learn about Overlay GHC and concurrent programming through development of a 4bit CPU simulator "G4"¹.

The material is under development, but the 4bit CPU simulator itself is ready. It is a software version of TD4 (Toriaezu Dosa surudakeno 4bit CPU; just barely working 4bit CPU), being designed in the book "How to Make a CPU" (Mainichi Communications) by Kaoru Tonami. The book is in Japanese, but if you can read it, perhaps you can enjoy this software, too.

>>How to Use

Exit wija, and copy the following files in the folder expanded from the downloaded file to plugins folder of wija.

org.media_art_online.circ.Circ.jar
org.media_art_online.circ.Circ.jar.sig

Then, restart wija.

The following files are 4bit CPU simulator programs written in Overlay GHC.

• g4-circ.ghc
  • "Ramen Timer" is inside the ROM.
• g4-led-circ.ghc
  • "LED Movement" is inside the ROM.
• g4-io-test-circ.ghc
  • A program to copy input to output is inside the ROM.
