<strong>Tornado</strong> 2.0<br />

User’s Guide<br />

Show box<br />

A text entry box where you can request display of system objects. See 6.6 Object<br />

Browsers, p.213.<br />

6.4 Browser Menus and Buttons<br />

The browser’s menu bar offers the standard <strong>Tornado</strong> menu entries: you can<br />

abandon the browser session by selecting File>Quit, query the <strong>Tornado</strong> version<br />

from the About menu, and peruse the <strong>Tornado</strong> Online Manuals from the Help menu.<br />

The row of buttons immediately below the menu bar provides browser-specific<br />

controls, with the following meanings:<br />

Immediate-update<br />

Periodic-update<br />

Stack-check<br />

Interrupt Vectors<br />

Spy<br />

Use this button to update all browser displays<br />

immediately. This button causes an immediate<br />

update even if a periodic update is running.<br />

This button is a toggle: press it to request or cancel<br />

regular updates of all browser displays. When<br />

periodic updates are on, the browser reflects this by<br />

displaying the word Update in its state indicator,<br />

below the button bar.<br />

This button produces a stack-usage histogram for<br />

all tasks in the target system (see 6.10 The Stack-<br />

Check Window, p.226).<br />

This button produces an interrupt vector table for<br />

all possible interrupt vectors. It appears only for<br />

those targets which support the interrupt vector<br />

table.<br />

This button is a toggle: press it to bring up a<br />

histogram displaying CPU utilization by all<br />

running tasks (see 6.9 The Spy Window, p.224). Press<br />

the button a second time to stop data sampling for<br />

the histogram.<br />
