<h1>Memory view</h1>
<p>The <b>Memory</b> view of the Debug
perspective lets you monitor and modify your process memory. The process memory
is presented as a list of so called <b>memory monitors</b>. Each monitor represents
a section of memory specified by it's location called <b>base address</b>. Each
memory monitor can be displayed in different predefined data formats -- <b>memory
renderings</b>. The debugger supports five rendering types -- <b>hexadecimal</b>
(default), <b>ascii</b>, <b>signed integer</b> and <b>unsigned integer</b>. The
default rendering is displayed automatically on the monitor creation.</p>
<p><img src="../images/view_memory.png" width="718" height="235"></p>
<p>The Memory view contains two
panes -- the <b>Memory Monitors</b> pane and the <b>Memory Renderings</b> pane. The
Memory Monitors pane displays the list of memory monitors added to the debug
session currently selected in the Debug view. The content of the Memory
Renderings pane is controlled by the selection in the Memory Monitors pane and
consists of the tabs that display renderings. The Memory Renderings pane can be
configured to display two renderings simultaneously.</p>
