Ghidra-Rare

Ghidra processor modules (SLEIGH) for uncommon CPU, DSP and GPU architectures. Target: Ghidra 12.1.4.

This project brings to Ghidra the set of architectures covered by Mr-wolf-is-me/IDA-Processor-Modules, a collection of IDA Pro processor modules. Each module here is the Ghidra counterpart of one of the IDA modules listed there.

Modules

Module	Architecture	Language IDs	Original IDA module
PRU	TI PRU / PRU-ICSS, core revisions V0–V4	PRU:LE:32:v0 … PRU:LE:32:v4	pru-ida
MicroBlaze	AMD/Xilinx MicroBlaze, 32/64-bit, BE/LE	MicroBlaze:{BE,LE}:{32,64}:default	microblaze-ida
xCORE	XMOS xCORE XS1, XS2 (xCORE-200), XS3 (xcore.ai)	xCORE:LE:32:XS1, XS2, XS3	xcore-ida
C7x	TI C7000 DSP (C7100, C7120, C7504, C7524)	C7x:LE:64:C7100, C7120, C7504, C7524	c7x-ida
SASS	NVIDIA GPU SASS, Kepler through Blackwell	SASS:LE:64:SM35, SM52, SM60, SM70, SM75, SM80, SM86, SM89, SM90, SM100, SM120	sass-ida

Each module's README lists its language variants, how closely it matches the reference disassembler, what the p-code models, known gaps and how to run its tests. STATUS.md tracks what works and what doesn't across all modules, plus lessons learned.

Relationship to the IDA modules

The IDA modules are distributed as release zips under terms that forbid derivative works; the repositories themselves hold only READMEs, licenses and screenshots. This project is an independent, clean-room implementation, not a port of that code:

• No IDA module binaries, source or release archives were downloaded, unpacked, disassembled or otherwise used. Only the public README files were read, as a list of architectures and features to cover.
• Instruction encodings and semantics come from vendor documentation (TI, AMD/Xilinx, XMOS) and published research. Each module was checked against vendor or open-source reference disassemblers (TI dispru/dis7x, GNU binutils, LLVM, NVIDIA nvdisasm).

Credit for the idea and for choosing these architectures goes to the author of IDA-Processor-Modules.

Installing

Each module directory is a standard Ghidra extension.

Prebuilt zips: the Release builds workflow builds every module for the three newest Ghidra releases. Each v* tag publishes the zips on the Releases page; other pushes keep them as workflow artifacts. A zip only installs into the Ghidra version in its name.

Build the extension zips yourself:

tools/build-release.sh /opt/ghidra_12.1.4_PUBLIC dist   # one zip per module in dist/

The script compiles the SLEIGH specs with that Ghidra's compiler and builds each module with the Gradle wrapper Ghidra ships in support/gradle. PRU, MicroBlaze and SASS include Java code (ELF loader extensions), so the build needs a full JDK with javac (a JRE-only package is not enough): JDK 21 or newer for Ghidra 12.1, JDK 25 for Ghidra 12.2. Point JAVA_HOME at it.

Install the zip via File → Install Extensions in Ghidra, then restart Ghidra.

For development, symlink every module into a Ghidra install and compile the SLEIGH specs:

export GHIDRA_INSTALL_DIR=/opt/ghidra_12.1.4_PUBLIC
tools/link-modules.sh
for d in */data/languages; do "$GHIDRA_INSTALL_DIR/support/sleigh" -a "$d"; done

tools/ghidra-dis.sh <language-id> <raw.bin> prints a headless linear-sweep disassembly of a raw binary, which is useful for quick checks.
