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

Clint Cole Gene Apperson Feng Zhao

• 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

Engineering is an applied skillApplied skills are learned through practice

Imagine learning to ride a bicycle just by reading about it!Step 1: Swing leg over bike and place feet on peddles without falling.

Step 2: Push forward and start peddling. Enjoy feeling of gliding down roadway.

Step 3: Important! Maintain balance while riding. Falling may lead to injuries.

Step 4: Always practice riding before getting on bicycle for first time to avoid falling off. Good Luck!

To learn engineering……students must do engineering

ChipKit for Arduino Community

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 # TDGL003Compatible Footprint with Arduino Mega2560• Featuring the PIC32MX795F512L MCU• Adds advanced comms and memory

Part # TDGL002Compatible Footprint with Arduino UNO• Featuring the PIC32MX320F128H MCU

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

Open-source Hardware is not just schematic & layout

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.

Open Source Hardware (OSHW) Statement of Principles 1.0

Open-source Hardware is not just schematic & layout

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.

Wiki - Open-source Hardware:

• AMD Opteron 64-bit processor– 1MB L2 Cache

• 193 mm sq– 0.18 micron CMOS

• 89W @ 1.8GHz• ~3 Op / cycle (int op)

• Full Custom ASIC– 4x4 SVD Decomposition

• 3.5 mm sq– 90nm CMOS

• 34mW @ 100 MHz clock• 70 GOPS = 700 Op / cycle

Actual computation

Open Source IP Cores• I/O Controllers• Soft Cores of Microcontrollers

– MIPS– freeARM, etc.– 8086– Microblaze

• Signal Processing Units– FFT & iFFT– IIR/FIR filters, etc.

A large community is working on it

• Websites– Digilentinc.com– Xilinx.wikidot.com– Opencores.org– Openhw.org

• Contests– Digilent Design Contest– Open Hardware Contest

– Sampling of projects• Tetris• Hexapod Spy Robot• Point-to-Point Robotic Car
