🛠️ Optimization Task: Improve findNext() in BtreeSF.java

Please help by optimizing the findNext() method in BtreeSF.java.

---

🎯 Goal

Refactor the findNext() method to use parallelStart() — similar to how it's used in the find() method.
This marks code regions that can be executed in parallel by the underlying bit machine, enabling better instruction scheduling.

---

✅ Tasks

• Review how find() uses parallelStart().
• Apply a similar structure to findNext().
• Ensure parallelizable instructions are grouped appropriately.
• Keep the logic correct — functional behavior must remain unchanged.
• Add/maintain inline comments for clarity.

---

📈 Performance Testing

You can verify your optimization with the following steps:

1. Run BtreeSF.java method with the call to test_first_last uncommented:

   • This will show the number of clock cycles used by findNext().
   • ✅ A successful optimization will reduce the number of clock cycles.

2. (Optional, for the brave): Run the generated Silicon Compiler output:

   • Make sure the optimized version still places and routes correctly.
   • This step ensures your changes are compatible with the hardware flow.
