Re: DSP memorymap problem

Silly question

160x120 = 19,200.

The DSP only has 32k words of space doesn't it? So 16k words each for X and Y memory?

Will your 19,200 size buffer be overlapping high memory where debugger code lives?
Logically your buffer in X memory will be from x:$200 to x:$4d00.

I think x:$3f00 maps to p:$7f00 and this is the debugger code area, and your buffer might trash that code.

(Forgive me, I'm very rusty on DSP stuff. I might be *totally* wrong)

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
