OpenCores design and publish core designs

Subsidiary objectives

  • Develop standards for open source cores and platforms
  • Create tools and methods for development of open source cores and platforms
  • Develop open source cores and platforms
  • Provide documentation for these cores and platforms

These tools and methods should allow large, widespread, even international, teams to develop hardware in an open way.

 

UART to / from fiber optic

This core is well tested. They is two versions: -Fixed baudrate (0 to 2.5Mbit/s) – a full set of 2 transmitter and 2 receiver fit in a single XC9572XL CPLD -variable baudrate 50Mhz/n*p where n between 20 to 100 fiber optic baudrate and p>=1 baudrate divider.
