Transcript

  • 1. Digilent &Open-Open-Source Hardware By Steve WANG CTO of Digilent Inc., China Office steven.wang@digilentinc.com
  • 2. Agenda• Ideas and Goals of Digilent – Applied skills are learned through practice• ChipKit for Arduino Community – chipKit Uno32 & chipKit Max32• Open Source IP Cores for FPGA – Opencores.org & Openhw.org – Digilent Contests & Openhw Contests
  • 3. Clint Cole Gene Apperson Feng Zhao
  • 4. Digilent• Founded in 1999 in Pullman, Washington – Two senior systems engineers (from HP and Microsoft) who joined the faculty at Washington State University• Vision: – Students need applied engineering skills – Bring leading technologies into the classroom • CAD, programmable devices, design practices and methods – Build long-term stable solutions (“institutionalize” products) – Target student needs; design for student ownership – Robust hardware to survive in challenging environments – Create and freely post teaching and reference materials
  • 5. Pullman, WA Main Office Clint Cole, President Engineering Design & Management Digilent Romania Digilent Taiwan 上海德致伦 Mircea Dabacan, Ph.D. Ben Liu, MSEE Digilent China Frank Zhao, Ph.D.Hardware/software design Manufacturing, ME design Support and marketing
  • 6. Engineering is an applied skill Applied skills are learned through practiceTo learn engineering… …students must do engineering Imagine learning to ride a bicycle just by reading about it! Step 1: Swing leg Step 3: Important! over bike and place Maintain balance feet on peddles while riding. Falling without falling. may lead to injuries. Step 2: Push Step 4: Always forward and start practice riding before peddling. Enjoy getting on bicycle for Good Luck! feeling of gliding first time to avoid down roadway. falling off.

  • 10. ChipKit for Arduino Community
  • 11. Introduction to two chipKits • First 32-bit, Arduino™ compatible platforms • Introduces unprecedented performance, memory and advanced peripherals to this community • Lower price-point than existing solutions Part # TDGL003Part # TDGL002 Compatible Footprint with Arduino Mega2560Compatible Footprint with Arduino UNO • Featuring the PIC32MX795F512L MCU• Featuring the PIC32MX320F128H MCU • Adds advanced comms and memory
  • 12. Introduction to two chipKits• Arduino™ compatible – Code compatibility with Arduino IDE and resources • Existing code will work on chipKIT™ platforms – Pin-out compatibility with many existing expansion shields that can operate at 3.3V – Complements existing solutions• Meeting the need for 32-bit solution requested by: – The hobbyist community – Academia (i.e. K thru PhD) – The embedded engineering community

  • 15. Same IDE
  • 16. Open-source Hardware is not just schematic & layoutOpen Source Hardware (OSHW) Statement of Principles 1.0 Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design.
  • 17. Open-source Hardware is not just schematic & layoutWiki - Open-source Hardware: Since the rise of reconfigurable programmable logic devices, sharing of logic designs has been a form of open source hardware. Instead of the schematics, hardware description language (HDL) code is shared. HDL modules, when distributed, are called semiconductor intellectual property cores, -- IP cores.
  • 18. Actual computation• AMD Opteron 64-bit processor • Full Custom ASIC – 1MB L2 Cache – 4x4 SVD Decomposition• 193 mm sq • 3.5 mm sq – 0.18 micron CMOS – 90nm CMOS• 89W @ 1.8GHz • 34mW @ 100 MHz clock• ~3 Op / cycle (int op) • 70 GOPS = 700 Op / cycle
