  2. Reminder - Project goals • Goal: Extending and analyzing RISC Processor using Bluespec • Part A: • Studying the working environment, BSV language and the basic processor implementation. • Logical design of processor modifications • Theoretical analysis of performance

  3. Work flow & progress • Learning Bluespec • Setting up the environment* • Study the simple RISC processor implementation • Assessing modification options. • Logical design of modifications. • Performance analysis and assessing of functional changes (theoretically). • Implementing and testing*.

  4. Modifications • Extend the basic RISC processor: • 1st phase: Extend the pipe. • 2nd phase: Add functional capabilities.

  5. The working environment • Will use platform by Shai and Dani. • Allowing us to focus on the processor. • The platform enables: • Synthesis of design to FPGA via Direct PC. • Cycle level control using COP. • Reading and writing to memories via JTAG.

  6. Pipe expansion • Goal: 5-stage pipeline • Pipe stages: Fetch, Decode, Execute, Memory, WriteBack • Including Data forwarding, Hazard detection.

  7. Other capability expansions • Branch prediction • 1-bit / 2-bit saturated counter • History bits • BTB • Cache • Replacement policies (LRU…) • Read/write policies • Indexing

  8. Performance analysis • Assess the processor’s capabilities • Instructions per cycle • Throughput • Latency • Miss rates • More
