About

• SpinalHDL design which compiles to Verilog or VHDL of a PowerPC 3.0B processor that implements just enough instructions to run micropython.
• Fmax of ~50Mhz on ECP5 if I remember correctly.
• Uses custom branch of SpinalHDL.
• At this point, I don't plan to complete this processor, but rather, plan to do a new implementation in BlueSpec. This paper demonstrates the power of bluespec for out-of-order processor design.
