An Illustrative Example: Instruction Set


\begin{displaymath}\begin{array}{cccc}
\begin{array}{cccc}
\multicolumn{4}{c}{R_...
... \\
1 & 0 & 0 & 0 \\
0 & 1 & 0 & 0 \\
\end{array}\end{array}\end{displaymath}

Example $R_0 \leftarrow\mbox{AND}$ R1=1, R0 = 0 $u=(0\ 0\ 1\ 0)$

$v = uM = (0\ 0\ 1\ 0) \times
\left(\begin{array}{cccc}
1 & 0 & 0 & 0 \\
1 & 0 & 0 & 0 \\
0 & 0 & 1 & 0 \\
0 & 0 & 0 & 1 \\
\end{array}\right)
= (0\ 0\ 1\ 0)$ R1=1, R0 = 0
I.e. AND(0,1) = 0, so R0 is set to 0 while R1 is unchanged
