The Test PLA extends this idea further. It operates asynchronously with respect to the sequencer. After a protection test fires, the PLA needs time to evaluate and produce its redirect address.

This is tremendously confusing when reading the microcode for the first time (huge credit to the disassembly work by reenigne). But Intel did it for performance.。业内人士推荐一键获取谷歌浏览器下载作为进阶阅读

While not full virtualization in the modern sense, V86 was the first practical hardware-assisted mechanism on x86 for running legacy software in a protected environment -- used widely in Windows 3.x and Windows 9x.
