+<h2>Interconnect Performance Counters View</h2>
+
+<p>Use the <strong>Interconnect Performance Counters</strong> view to monitor
+Processor Sub-System (PSS) bus (VIA) accesses. By default, the Interconnect
+Performance Counters view opens up as minimised on the PIAnalyzer main view. To
+view the graphs, click the restore button <img
+src="images/minimize_restore_graph.png" width="16" height="16"> or the maximize
+button <img src="images/maximize_graph.png" width="16" height="16"> on the
+Title bar.</p>
+
+<p>The graph portion of the Performance Counters view displays graphs of the
+selected traces. From all the IPC counters five different values are collected:
+cycle, read, write, wait and idle counts. Those are shown on separate lines in
+the graphs view, and the legend table. To select a trace for the graphs view,
+click the check box next to the trace name in the legend table.</p>
+
+<p>In the top left-hand corner of each graph line, the following information
+displayed:</p>
+<ul>
+ <li>Type of the trace</li>
+ <li>Sampling interval</li>
+</ul>
+
+<p>Note that the scaling of the graphs changes according to the maximum values
+for each graph. You can see the vertical axis values for each graph on the left
+side of the graph.</p>
+
+<p>You can move the mouse pointer on top of the graph lines to see the values
+as a tooltip, as shown below in Figure 1.</p>

+
+<p>A legend table is displayed below the graphs. </p>
+
+<p>Description of the table columns: </p>
+<ul>
+ <li>The <b>Char</b> column contains an identifier for each trace.</li>
+ <li>The <b>Name</b> column contains the type of performance counter that was
+ traced.</li>
+ <li>The <b>Average (1/ms)</b> column contains the average occurrence of the
+ event that was traced, within the selected timeframe.</li>
+ <li>The <b>Sum</b> column contains the total number of event occurrences
+ within the selected timeframe.</li>
+ <li>The <b>Min (1/ms)</b> column contains the minimum occurrence of the event
+ that was traced, within the selected timeframe.</li>
+ <li>The <b>Max (1/ms)</b> column contains the maximum occurrence of the event
+ that was traced, within the selected timeframe.</li>
+</ul>
+
+<p>Check the boxes at the left side of the table to select the traces for the
+graphs view.</p>
+
+<p>Columns may be reordered, resized, and sorted by clicking or dragging column
+headers.</p>
+
+<p>You can right-click on the table to open a context menu, where you can
+select to copy either selected lines or the entire table to clipboard; or to
+save the table to CSV format. </p>
