Propeller Chip General Information
by deepgeek at 10:23 am EDT, Apr 26, 2009

This amazed me, now microcontrollers boast eight 32 bit cores!
If you visit their site, check out the audio of four part harmony (each part having it's own core, I believe.)

...Its eight processors cogs can operate simultaneously, either independently or cooperatively, sharing common resources through a central hub. The developer has full control over how and when each cog is employed; there is no compiler-driven or operating system-driven splitting of tasks among multiple cogs.
...Two programming languages are available: the easy-to-learn high-level Spin, and Propeller Assembly which can execute at up to 160 MIPS 20 MIPS per cog .
Who uses the Propeller?
Due to its diversity, the Propeller Chip may be used for many types of applications. Most users appreciate the overall processing power and I/O capabilities. Hobbyists like the powerful yet easy language while robot builders and process control engineers appreciate the parallel processing capabilities. Many find the on-board video generation and easy connection to popular PC peripherals reduces the need for additional support components.

Where is the Propeller used?
The Propeller is used in many industries including manufacturing, process control, robotics, automotive and communications. Hobbyists and Engineers alike are finding new uses for this powerful microcontroller every day.

This came to my attention listening to a podcast on embedded linux. The thing that interested the podcasters was that this chip was designed without circuitry for interrupts. The company says that during the design, the engineers saw interrupts as a band-aid for not having enough cores, so they killed the interrupts, and put in eight cores. Other features are on-board video generation. All on one chip. Far out!
