OpenCores design and publish core designs

"Our main objective is to design and publish core designs under a license for hardware modelled on the Lesser General Public License (LGPL) for software. We are committed to the ideal of freely available, freely usable and re-usable open source hardware. OpenCores.org"

OpenCores design and publish core designs

Subsidiary objectives
  • Develop standards for open source cores and platforms
  • Create tools and methods for development of open source cores and platforms
  • Develop open source cores and platforms
  • Provide documentation for these cores and platforms
These tools and methods should allow large, widespread, even international, teams to develop hardware in an open way.

Embedded Systems Made Easy - StickOS

StickOS BASIC is intended to make embedded systems technology and advanced microcontroller functionality quickly and easily accessible to High School students, hobbyists, and researchers, etc., with minimal investment of time, education, and money.

Embedded Systems Made Easy - StickOS

Interfacing with digital circuitry, analog circuitry, serial circuitry (UART and SPI), servo motors, and buzzers, etc., all become trivial single-line, single-minute tasks in StickOS BASIC, so the user can concentrate on achieving the control task at hand, rather than the detailed mechanics of control.

StickOS Examples - A simple embedded system, like a toaster oven temperature profile controller, can be brought online in record time!

- Rich Testardi (mail)

Embedded Systems Made Easy – StickOS

"StickOS BASIC is an entirely MCU-resident interactive programming environment, which includes an easy-to-use editor, transparent line-by-line compiler, interactive debugger, performance profiler, and flash filesystem, all controlled thru an interactive command-line user interface….

CPUStick is a 1″x4″ very low cost standalone USB embedded computer based on the Freescale MCF52252 ColdFire MCU and MC13201 ZigFlea Wireless Transceiver,…"

QuickLogic - Flexible Semiconductor Platforms

Products for the hand-held mobile device market. Platforms include ArcticLink for Customer Specific Standard Product (CSSP) solution in the display and connectivity subsystems of Smartphones, Smartbooks, Netbooks, Mobile Internet Devices. PolarPro for the interconnect and system logic requirements of power sensitive and portable applications.

QuickLogic - Flexible Semiconductor Platforms

Along with the hard logic blocks, the CSSP offers a programmable fabric. Based on QuickLogic’s patented ViaLink technology, this fabric provides a highly compact, low-power resource that can
implement virtually any logic function the development team requires. The fabric is non-volatile, so once programmed it does not need any external memory-based boot source nor does it suffer any start-up delay.
