  • microwatt

    A tiny Open POWER ISA softcore written in VHDL 2008

    Why dismiss POWER or SPARC ? :-)

  • I'd say beyond availability, the primary advantage for embedded use it the adaptability of the ISA. If you just need a small microcontroller, the core can be very small; if you need some specific performance point, you can use a bigger core, some extensions (or part thereof) could help, and you can always roll your own instructions in the 'custom' opcode space to reach your goals.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • vISA

    Well, the simplest ISA is six lines of Verilog and it's called Bit-Bit-Jump

  • ao486_MiSTer

    ao486 port for MiSTer
