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

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.
