MCOC115-TD

This is Moscovium series MCU projects for Sipeed Lichee Tang Primer FPGA board.

• Anlogic TD IDE project
• Development on this FPGA board (Primer) has been frozen.
  • Development is progressing on another FPGA board (Cmod A7).
  • See MCOC115-VD repository.
• MCOC: Moscovium (Mc) On Chip
  • 115 is the atomic number of Mc (Moscovium).
  • 117 for Ts (Tennessine), 113 for Nh (Nihonium).

Moscovium series

Moscovium is an original 16 bit CPU core.

More options for the Moscovium series here:

1. Tennessine
   • 8 bit data path
2. Moscovium
   • 16 bit data path
3. Moscovium-SS
   • 16 bit data path x2
   • Super Scalar
4. Nihonium
   • 32 bit data path
5. Nihonium-SS
   • 32 bit data path x2
   • Super Scalar

Moscovium series CPU cores are scalable from 8 ~ 32 bit data paths.

• The order listed above is roughly a trade-off between performance and size (LUTs).
  • Lower performance takes smaller size.
  • Higher performance takes larger size.
