Parallax P8X32A-Q44

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.

• True parallel processing with eight symmetric 32-bit processors (cogs) in one microcontroller
• Multi-cog run-time management (run/wait/stop) easily solves event-handling problems and eliminates the need for interrupts
• 20 MIPS per cog, 160 MIPS total with all cogs running
• Solves mixed-bandwidth needs common to embedded applications
• Multi-purpose design lowers part count while increasing system capabilities
• Developer-driven cog assignments bring flexible response and deterministic timing to embedded applications
• Flexible Clock Modes: Two internal, one external, plus optional 1x - 16x PLL; up to 80 MHz system clock
• Switchable in code at run-time; low frequency for low-power periods, high frequency for high-bandwidth moments
• Shared System Clock facilitates synchronization between cogs
• WAIT Instructions: Deliver powerful synchronous/asynchronous event management; Set dedicated event cogs to an "always ready," very low power state
• Spin (object-based, high-level) and Assembly (PASM; low-level) used together for thorough development
