 # HERACLES Code Generation Framework (Reference Implementation)
 
-The tools in this directory are the reference implementation of and Assembler codegenerator that takes a pre-generated Polynomial Instruction Set Architecture (P-ISA) program containing instructions that use an abstract, flat memory model for polynomial operations, such as those applied in homomorphic encryption (HE), and maps them to a corresponding set of instructions compatible with the HERACLES architecture, accounting for hardware restrictions, including memory management for the HERACLES memory model.
