"The LVDC was capable of executing 12190 instructions per second."

People often over estimate how much performance is needed to run LV's and their engines in steady state, with limited monitoring

OTOH if you're doing turbine monitoring using FFT's of the vibration spectrum of the drive turbines to decide if you need to shut down rather than get away with a throttle down (developed, but not AFAIK flown, for the Shuttle) and do fault diagnosis on the sensors (to decide if you can trust their readings) you need something with a bit more "oomph" (In Shuttles a whole separate processor board in the box).
