1: Introducing the Propeller Chip
Cog and Hub interaction is critical to the Propeller chip. The Hub controls which cog can
access mutually-exclusive resources, such as Main RAM/ROM, configuration registers, etc.
The Hub gives exclusive access to every cog one at a time in a “round robin” fashion,
regardless of how many cogs are running, in order to keep timing deterministic.
