so IRQ's themselves have no priority attached to them, but when handled by the PIC, they are prioritized by the PIC?Tony The Lion– Tony The Lion2010-01-02 11:57:45 +00:00Commented Jan 2, 2010 at 11:57

Oh, we're talking about PIC processors. You tagged the question 'windows'. I don't know about PICs, but it seems to me that if handling the IRQs is handled by software, anything is possible. Sorry, I can't be more specific because I don't know what the software does.pavium– pavium2010-01-02 12:31:26 +00:00Commented Jan 2, 2010 at 12:31

1I looked in Wikipedia, and found you meant Programmable Interrupt Controller. There was no mention of 'priority' in the article, so I must conclude that any prioritizing is indeed done by software. You can do anything with software, you know ;-Dpavium– pavium2010-01-02 12:39:35 +00:00Commented Jan 2, 2010 at 12:39

IRQ in the general PC sense means "interrupt request line". different IRQs meant different addresses, and allowed multiple devices to interrupt the processor without sharing an interrupt line. had nothing to do with priority.quack quixote– quack quixote2010-01-02 13:19:49 +00:00Commented Jan 2, 2010 at 13:19

How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
