Presentation Transcript

  1. TEAM SMASH The Pipelined Megacessor

  2. Architectural View • Top Level Design • Pipeline Stages • Instruction Fetch • Instruction Decode • Execution • Data Memory • Register Write-back

  3. Top-Level View

  4. Instruction Fetch Stage

  5. Instruction Decode Stage

  6. Execution Stage

  7. Memory Stage

  8. Write Back Stage

  9. High-Level Components • Talk about connection between high level components • Highlight our idea of the pipeline, branch predictor and memory hierarchy

  10. Debug Components • Seven Segment Display • LCD Display • Pipeline value switch • Clock Divider

  11. LCD Display

  12. Significance of Pipeline • Increase instruction throughput

  13. Branch Predictor • Explain the hardware involved

  14. Significance of Branch Predictor • Predict what the next PC address will be. • Keeps the pipeline flowing • Our implementation – Always not taken • As suggested by Instructors • Simple approach but similar idea to more complex solution

  15. Significance of Memory Hierarchy • Registers • only 32 but very fast • Cache • stores data from most frequently used main memory • Memory

  16. Assembler • PYTHON!!!! • The dictionary data structure • regDict – register encoding • dataAddyDict – Data Label  Address • branchAddyDict – Branch Label  Address

  17. Assembler • readData() • 2 Passes • Create dictionary of label-address mappings • Encode all data and output to mif • readText() • 2 Passes • Create BranchAddyDict • Encode all instructions using dictionaries

  18. Assembly Code • Matrix Multiplier! • Snake it the size and two matrices • Multiply! • Wam bam output the diagonal

  19. Teamwork

  20. What we learned • From course, project and other people

  21. ALSO WE ARE FREE TO TALK ABOUT WHATEVER WE WANT!!! • I say we discuss the renegades of funk and how they contributed to our success!
