Building Block – Binary Translation
{"Image DocumentName": "Building Block \u2013 Binary Translation", "Image ImageDescription": "Some CPUs don\u2019t have clean separation between privileged and nonprivileged instructions. Earlier Intel x86 CPUs are among them. Earliest Intel CPU designed for a calculator. Backward compatibility means difficult to improve. Consider Intel x86 popf instruction. Loads CPU flags register from contents of the stack. If CPU in privileged mode -> all flags replaced. If CPU in user mode -> on some flags replaced. No trap is generated.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
