Ditty: Directory-based Cache Coherence for Multicore Safety-critical Systems

• aws: useful scripts for linking the hls designs and RTL interconnect within the AWS server
• intc_analysis: the analysis for calculating interconnect latency
• hls: the implementation of the private caches and the LLC, the main designs are in private_cache.cpp and llc.cpp
• hoplite-rt: the RTL design of the HopliteRT interconnect
• integration: the integration of the design with the interconnect, where the caches/interconnects/LLCs are treated as blackboxes in SpinalHDL
