Propeller

The Propeller chip is a multicore microcontroller that is programmable in high-level languages (Spin™ and C) as well as a low-level (Propeller assembly) language.  Application development is simplified by using the set of pre-built objects for video (NTSC/PAL/VGA), mice, keyboards, LCDs, stepper motors and sensors.

The Propeller is designed with an emphasis on general-purpose use, with powerful capabilities that are great for customized high-speed embedded processing, while maintaining low power, low current consumption and a small physical footprint.  The Propeller's processors are all identical, each with its own separate memory, and each with an identical interface to all 32 I/O pins and internal shared memory.  The architecture is built for swift processing of asynchronous events, equal access to internal and external resources, and dynamic speed and power when it's needed.
