 XS-GEM5 is enhanced with
 - Xiangshan RVGCpt: a cross-platform full-system checkpoint for RISC-V.
 - Xiangshan online Difftest: an API to check execution results online.
-- Frontend microarchitecture calibrated with Xiangshan V2 (Nanhu): Decoupled frontend, TAGESC, and ITTAGE,
-which performance better than LTAGE and TAGE-SCL shipped in official version on SPECCPU.
-- Instruction latency calibrated with Nanhu
-- Cache hierarchy, latency, and prefetchers calibrated with Nanhu.
-- A fixed Multi-Prefetcher framework with VA-PA translation support
-- A fixed BOP prefetcher
-- Parallel RV PTW (Page Table Walker) and walking state coalescing
