Exam question 1.3 (fwd)

Show all headers | View raw

Is the Shake interface supposed to be a one-shot interface, i.e.
"Shake(0b101)" shakes tiles 0 and 2 once; or is it supposed to be a
stateful interface, i.e. "Shake(0b101)" turns on shaking for tiles 0 and 2,
turning it off for other tiles, with the intent of sending "Shake(0)"
later; or is it something else?

If it's the former, for how long do you need to assert the output?

The interface is not stateful. It is one-shot triggered by a rising
edge on its input. You do need to turn it off to shake again in the
future, but you don't have to turn it off immediately.

Thanks, Bill
