Ghidra processor description module for NEC/Renesas v810 and v830 families

These modules were made by taking the v850 modules that come with Ghidra as a template and rewriting them to work with v810 and v830 family instructions.

2. V830 description based on User’s Manual: V830 Architecture (link)

Installation

1. Compile the SLEIGH CPU descriptions with:

$(GHIDRA_HOME)\support\sleigh.bat data\languages\V810.slaspec

$(GHIDRA_HOME)\support\sleigh.bat data\languages\V830.slaspec

2. Copy the V800 folder to: $(GHIDRA_HOME)\Ghidra\Processors\

Hardware Documentation

Some CPUs, such as the v831, come with built-in peripherals (i.e. DMA controller, UART, CSI, Timers, etc.). Therefore, if hardware documentation for a CPU in these families is available (with or without peripherals), they will be listed below:
