  1. MIPS Pipeline and Branch Prediction Implementation Shuai Chang

  2. Project Overview • ECE 369 Project Single Cycle Datapath • Easy to implement • Poor performance • Performance Consideration • Resource utilization • Pipeline implementation • Pipeline + Branch prediction

  3. Original Design

  4. Methodology • Implemented in Verilog HDL • Simulation • Xilinx ISE 13.2 • Hardware • Xilinx Spartan 3E FPGA Devlopment Board

  5. Methodology • Implementation • Pipeline • Branch prediction

  6. Methodology • Inputs • 2 files: Assembly Program and Data file 16 * 16 Window 32 * 32 Frame X = 0, Y = 8, SAD (Sum of Absolute Difference) = 0 is expected to be returned

  7. Assembly Program Executed

  8. Methodology • Outputs • Returned X, Y • SAD • Execution Time = CycleCount * CriticalPathDelay

  9. Results

  10. Start Earlier? • Support more instructions • Optimize logic • Cache implementation

  11. Questions?
