Js.Emu Decoder Library

This library includes structured raw data of ISA related specs.

The data will be needed to either generate runtime core of JEMU (cpu emulator) or to auto-generate a wiki site.

Contributors wanted!

We are looking for coordinators for this project. Any amount and any form of contributions are welcomed.

Please take a look at contribution guide to get started.

Project Structure

• /arch

  The core directory containing the definitions of all instructions. See instruction definition and instruction documentation format.

• /lib

  Common utilities and dependencies.

• /scripts

  Scripts used to build the decoder and parser.

• /targets

  Manifests declaring which instruction(s) to be included for a specific build.

• /web

  A magical sub-project converting the build results into a handy manual. The decoder and parser we built in the parent project will be embedded into its runtime core, enabling search and decode of binary instructions.

Build the decoder

# Run at project root
jemu-decoder > npm run build

If you made changes to the content of /arch and want to get it reflected in the webpages, you have to run this command.

Build for web

1. Build the decoder

   # Run at project root
   jemu-decoder > npm run build

   If you made any change to the content of /arch and want to get it reflected in the webpages, you have to run this command.

2. Preview webpages

   # Run at web folder
   jemu-decoder/web > npm run dev

   This command will launch a local server showing live updates of the web contents. vite is used under the hood.

   When dev server is running, you can modify the code under /arch, and then manually build the decoder to see live updates.

3. Build and deploy (only available for YSYX stuff with certain privileges)

   To build for web only (without deploying)

   # Run at web folder (build)
   jemu-decoder/web > npm run build

   To build and deploy (with privileged account)

   # Run at web folder
   jemu-decoder/web > npm run deploy
