Micro-controller
utilizing an architecture that, in many aspects, is different from other commercially available micro-controllers, Parallax released the Propeller, based on a completely symmetrical arrangement of eight RISC processors (Cogs) that work autonomously processing controller tasks either individually or in co-operative groups.
Each Cog is clocked at up to 80 MHz, delivering a maximum of 20 RISC MIPS (4 cycles per instruction). In addition, there’s a sophisticated clock management system, which allos for standy operation at less than 10µA at 3.3 V supplies.
Besides 32 Kbyte global RAM and 32 Kbyte ROM containing character sets, sine wave and log/antilog tables, each Cogowns 2 Kbytes local RAM. Moreover, there is not prioritization among the Cogs and each Cog can carry out tasks individually.
