EP4CE6 Resources

• Cyclone IV lowest end part
• Logic Elements (LEs) = 6276
• Embedded Memory (1Kx9 blocks) = 30

Advantages to the Spartan as a target

• Spartan FPGA boards are inexpensive and widely available.
• There's enough BlockRAM in a Spartan FPGA to have separate Instruction, Data and Stack Memory spaces.
• This makes CPU design much simpler since there's very little need for multiplexing of address/data for common busses.
  • Produces significant bandwidth improvements
• See the Architecture document(s) for details.

Porting to other FPGAs

• Porting R32V2020 to other FPGAs.

Ownership

• We all stand on the shoulders of giants.
• The concepts in this RISC design are found in any Computer Architecture Design textbook.

Warning

• Use at your own risk.
  • If you brick your part or it melt to a puddle, it's on you not me.
