A data driven machine is one that executes an instruction if the needed data is available. The physical ordering of the code listing does not dictate the course of execution. Consider the following pseudo-code: Multiply $E$ by $0.5$ to get $F$ Add $A$ and $B$ to get $E$ Add $B$ with $0.5$ to get ... sequence of execution is valid? B, C, D, A, E C, B, E, A, D A, B, C, D, E E, D, C, B, A

In the diagram above, the inverter (NOT gate) and the AND-gates labeled $1$ and $2$ have delays of $9, 10$ and $12$ nanoseconds (ns), respectively. Wire delays are negligible. For certain values $a$ and $c$, together with certain transition of $b$, a glitch (spurious output) is ... correct value. The duration of glitch is: $7\;\text{ns}$ $9\;\text{ns}$ $11\;\text{ns}$ $13\;\text{ns}$
