The article summarizes the development of an FPGA-based 80386 core that runs DOS and games at 75 MHz, then shifts focus to analyzing the processor's memory pipeline. It explains that while the 80386's…
The article discusses the 80386 processor's improved protection model, which added paging, a flat 32-bit address space, and Virtual 8086 mode to make protected mode usable after the 80286's unpopular …
The article describes the author's project to build an 80386-compatible processor core in SystemVerilog using original Intel microcode, with real mode operational and over 10,000 test cases passing. I…
The Intel 80386, released in 1985, was the first 32-bit x86 processor, introducing a flat 4GB address space, virtual memory with paging, and an effective protected mode. It significantly improved arit…
