PLX 1.1

Architecture

• PLX 1.1 ISA Reference
• PLX 1.1 ISA Encoding

Toolset

• Installation and usage guide for the PLX toolset (which includes the assembler, compiler, simulator, and the VHDL model for a PLX processor).
• README and INSTALL files for the PLX compiler.
• This guide for the PLX backend for the Lcc compiler was written by Wei Qin as a class project. It details what changes were made to the original Lcc code to make it generate PLX code, how intrinsics are used and added, how predication is supported, etc. A companion presentation is here.
• This README file contains a brief introduction to the VHDL model and some warnings.
• The full documentation of the VHDL model and a companion PowerPoint presentation.

Download Toolset

PLX Developers can login and access the download page for the PLX 1.1 toolset.

The downloaded file can be extracted with the command 'tar -xzvf PLX-1.1.tgz'. Under the PLX-1.1 directory, there will be 8 subdirectories:

• assembler - contains the asm script, which is the PLX assembler
• benchmarks - contains the PLX benchmarks written in PLX assembly and C
• build - initially empty, this is where the binary executable for the simulator is built
• compiler - source code for the PLX compiler (see the README and INSTALL files in this directory for how to install the compiler)
• scripts - Perl scripts used to automate the build process
• simulator - source code for the PLX simulator
• ISA - contains the PLX architecture definition
• vhdl - contains the VHDL model for a PLX processor

For more detailed installation and usage instructions, see the Documentation page.

Notice: Some users have reported problems with the build process. This is almost always due to the fact that the PLX code does not use portability tools (e.g. autoconf, automake, etc.) at this time. Future releases of the code will come in a more properly-structured GNU-like format. If you run into any persistent problems in building or using the tools, contact dav@princeton.edu.

Architecture

• PLX 1.0 ISA Reference
• PLX 1.0 ISA Encoding

Toolset

PLX 1.0 was released as an ISA specification only and had no accompanying software tools.
