In case of any discrepancies or ambiguities, the original Chinese version shall prevail. Current AMD Zen-series CPUs (e.g., EPYC 9004 series) have begun integrating RISC-V coprocessors for specific acceleration tasks. The microcode of AMD Zen-series processors enables modification of low-level CPU instruction execution behavior through software-level firmware patches, making it suitable for optimizing instruction execution and altering specific instruction behaviors. Zentool, developed by Google's Security Research team, is a toolkit for analyzing, modifying, and generating microcode patches for AMD Zen-series processors. Microcode Patch: Complete microcode modifications for Zen-series CPUs to enable direct execution of RISC-V binary programs. If direct ex ... Read full article.
