\section{Architecture Identifier String (\texttt{ArchID})}
The best way to understand the multifaceted parameterizablity of the HARP ISAs is to study the architecture identifier strings used to uniquely identify a single HARP instruction set architecture.
We'll start by breaking down Harptool's default \texttt{ArchID}: \texttt{8w32/32/8}:

All ArchIDs have a similar format, although the SIMD lanes field can be omitted, as object files are still fully compatible even if the number of lanes changes.
All ArchIDs have a similar format, although the final two fields can be omitted, as object files are still fully compatible even if the dimensions of the core change.

The assembler/linker/emulator/disassembler program for HARP is called HarpTool.
