The 80386 introduced Virtual 8086 (V86) mode -- allowing real-mode DOS programs to run inside protected mode under OS supervision. 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.
，这一点在WPS官方版本下载中也有详细论述

int4 — 最大程度的压缩，文件大小减少约 4 倍。质量损失更明显（约 2~10%，具体取决于模型），但通常可以接受，尤其对于函数调用而言。
This algorithm attempts to minimise numerically. Because of this, the quality of the dither produced by Knoll’s algorithm is much higher than any other of the N-candidate methods we have covered so far. It is also the slowest however, as it requires a greater per-pixel to be really effective. More details are given in Knoll’s now expired patent[3]. I have put together a GPU implementation of Knoll’s algorithm on Shadertoy here.
