The Propeller chip (See PARALLAX) makes it easy to rapidly develop embedded applications. 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. A shared system clock keeps each cog on the same time reference, allowing for true deterministic timing and synchronization. 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).
The Propeller chip is designed to provide high-speed processing for embedded systems while maintaining low current consumption and a small physical footprint. In addition to being fast, the Propeller chip provides flexibility and power through its eight processors, called cogs, that can perform simultaneous tasks independently or cooperatively, all while maintaining a relatively simple architecture that is easy to learn and utilize. Two programming languages are available: Spin (a high-level object-based language) and Propeller Assembly. Both include custom commands to easily manage the Propeller chip’s unique features.
