CE-653 - Introduction and
Fundamentals
34
}Reduced Electromagnetic Noise
}No global clock
}Frequency spread out much more
}Co-locate with sensitive analog
}Less noise - does not effect analog circuitry
}Others argue not critical
}Analog circuitry can be designed to be insensitive to clock
noise
}Ease of modular composition
}Supports GALS design for multi-frequency
disparate SoC designs
}Handshaking offers plug-and-play IP
}Adjusts to operating conditions/process
variations
}Supports easy voltage scaling (no need
to pair voltage/frequency)
}Immediate start-up (no need to wait for
clock to stabilize)
}Go quiet
}Run fast
}Go quiet again
