2. Important Persons Client –Dr. Aaron Collins Technical Advisor –Dr. John Reece Project Manager –Dr. Phillip Olivier

3. Overview PDR Review Delivered Design –Hardware –Software DemonstrationBudgetConclusionRecommendations

4. Client Requirements Update ECE 424 and ECE 426 Use state of the art technology Prepare for new industry trends Deliver teaching device Deliver lab manual

5. Feasibility Criteria Low budget ($300 maximum) Compatible with Win98 or WinXP Applicable to ECE 424 and ECE 426

6. PDR Design Alternatives SOPC with RTOS SOPC without RTOS Microcontroller with RTOS Microcontroller without RTOS VHDL

7. Design Selected - PDR Phase Selected SOPC with RTOS Design NIOS II Evaluation Edition –MicroC/OS-II feature disabled Design Change –SOPC without RTOS Design Addition –Implemented VHDL Design

8. Why SOPC? One chip –Simplified design –Less hardware Supports VHDL & current curriculum Nios II Soft-core Processor –C/C++ –Assembly Expedite upgrades
