OpenSOC86
Open implementation of the x86 architecture
OpenSOC86 is an open implementation of the x86 architecture in Verilog. The current version only implements the 16-bit part (real mode). The processor is a pipelined architecture clocked at 100 MHz in a Cyclone II speed grade -6. Therefore it can be seen as similar to a 486 in real mode.
Several peripherals are also implemented in a somewhat minimalistic way, but enough to be able to boot an IBM PCXT compatible bios and MSDOS 6.22. The current implementation is only proven to boot the bios...
