I'm building an 80386-compatible core in SystemVerilog and blogging the process. In the previous post, we looked at how the 386 reuses one barrel shifter for all shift and rotate instructions. This time we move from real mode to protected and talk about protection.
不过，这些原则并非不可更改。每一代人都应重新审视它们，并在必要时修改、补充。把它们当作你工作的心理指南。

更值得警惕的是，民德电子历史募投项目的失速表现，为本次扩产蒙上阴影。2022年公司曾完成5亿元定增，投向碳化硅功率器件研发产业化、高端沟槽型肖特基二极管产能提升两大项目，最终均未达到预期效益。
The performance characteristics are attractive with incredibly fast cold starts and minimal memory overhead. But the practical limitation is language support. You cannot run arbitrary Python scripts in WASM today without compiling the Python interpreter itself to WASM along with all its C extensions. For sandboxing arbitrary code in arbitrary languages, WASM is not yet viable. For sandboxing code you control the toolchain for, it is excellent. I am, however, quite curious if there is a future for WASM in general-purpose sandboxing. Browsers have spent decades solving a similar problem of executing untrusted code safely, and porting those architectural learnings to backend infrastructure feels like a natural evolution.
