DEPRECATION WARNING: NaCL and PNaCL have been deprecated, so this project may no longer function in a modern version of Chrome. The project remains here for posterity, as an example of how NaCl and PNaCL were used.
Version: 0.1.0
An experimental port of the JavaScript OpenRISC 1000 emulator to C++ using Chrome's NaCl/PNaCl libraries, allowing it to be run in the Chrome browser or Chrome OS (not Chrome for Android/iOS).
A demo is available. This
provides a basic Linux build with a few fun terminal programs in /usr/bin.
Compared to the JavaScript emulator, this emulator currently has a few prominent limitations:
- The Ethernet device is not emulated.
- The Touchscreen device is not emulated.
In terms of differences in emulated hardware, this emulator has 128MB of RAM by default, a 200MB hard disk image and a 120 x 40 terminal window (1680x1050 or higher screen resolution recommended).
- Pepper SDK (tested with Canary)
- BZip2 library (in the NaClPorts repository)
- Python (tested with 2.7.3, but should work with 2+)
A suitable version of the Pepper SDK tools must be installed. Consult the Pepper SDK download page for details.
The environment variables NACL_ARCH and NACL_SDK_ROOT should be set
appropriately (the former indicating the target architecture, e.g. pnacl;
the latter indicating the path to the Pepper SDK).
The BZip2 library must be present in the Pepper SDK area. For information on how to build and install this library, please consult the NaClPorts repository.
To make the development build and place the result under ./dist/:
make
To remove all build files:
