Scripting a Processor Module

Introduced in IDA 5.7, the capability to create processor modules using one of IDA’s scripting languages somewhat simplifies the creation of processor modules. If nothing else, it completely eliminates the build phase of module creation. Elias Bachaalany of Hex-Rays introduced scripted processor modules in a post on Hex Blog^[139] and IDA’s EFI bytecode processor module is implemented as a Python script (see <IDADIR>/procs/ebc.py). Note that while the Hex Blog post serves as useful background, the actual API used for scripting processor modules seems to have evolved. The best place for you to start development of your own processor module script is with the template module that ships with the SDK (see <SDKDIR>/module/script/proctemplate.py ...
