我想将重复路径代码(-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25)移出作用域环境。我可以命名此路径，然后在作用域块内引用它吗？
\begin{scope} [mem/.style={upper left=gray!40, very thin}]
\node[draw, black, thick, minimum width =4cm,
minimum height=6cm, fill=teal!15] (rambox) at (-1.5,0) {};
\node[black,scale=1.0] at (-1.5,2.7) {\textsf{MEMORY}};
\node[blue,scale=0.8] at (-1.5,-2.7) {$2^{32}$ bytes $\approx 4.29$ GB};
\node [matrix] (ram) at (-1.5,0)
{
\node[blue] {Address} ;& \node[blue] {Content}; & \\
\node { \memcellsize \texttt{0xffffffff}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) -- cycle ; & \\
\node { \memcellsize \texttt{0xfffffffe}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) -- cycle ; & \\
\node { \memcellsize \texttt{0xfffffffd}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) -- cycle ; & \\
\node {$\ddots$} ;& \node{$\ddots$}; & \\
\node { \memcellsize \texttt{0x00000003}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) --cycle ; & \\
\node { \memcellsize \texttt{0x00000002}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) --cycle ; & \\
\node { \memcellsize \texttt{0x00000001}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25); & \\
\node { \memcellsize \texttt{0x00000000}} ;& \shadedraw [mem] (-0.5,.25) -- (-0.5,-.25) -- (0.5,-.25) -- (0.5,.25) ; & \\
};
\end{scope}
同样，我想将Stealth{}下面给出的选项移动到 tikz 环境的开头。
\draw[{Stealth[length=2mm, width=2mm]}-{Stealth[length=2mm, width=2mm]},thick] (iocntrl) -- (storage1);
\draw[{Stealth[length=2mm, width=2mm]}-{Stealth[length=2mm, width=2mm]},thick] (iocntrl) |- (rambox) node [near end, fill=white, text width = 1.5cm] {\footnotesize{Load/Store}};
\draw[{Stealth[length=2mm, width=2mm]}-{Stealth[length=2mm, width=2mm]},thick] (iocntrl) |- (regbox) node [near start, fill=white] {\footnotesize{syscall}};
\draw[{Stealth[length=2mm, width=2mm]}-{Stealth[length=2mm, width=2mm]},thick] (iocntrl) -- (userio);
