That’s not what the datasheet says. It says: ”... its eight processors, called cogs, that can perform simultaneous tasks independently or cooperatively...” ” True parallel processing with eight symmetric 32-bit processors (cogs) in one microcontroller” ”20 MIPS per cog, 160 MIPS total with all cogs running” ”All eight cogs are driven from the System Clock; they each maintain the same time reference and all active cogs execute instructions simultaneously.” https://www.parallax.com/sites/default/files/downloads/P8X32A-Propeller-Datasheet-v1.4.0_0.pdf https://www.parallax.com/sites/default/files/downloads/P8X32... The shared hub memory is only accessible to one core at once and which one has access is switched between in round robin fashion, each core getting a turn to access it once every 16 clock cycles. Perhaps that’s what you were thinking of?
