Delay RAM - 14-bit Compress
Posted: Thu Aug 16, 2007 4:28 pm
I have alot of experience with high end DSPs (TI C6713 for example) but have been looking for a device such as this one for a tiny application.
I do have one question about the Delay RAM. I read in the knowledge base that the ADC is 24-bit but the Delay RAM is a 14-bit floating point format.
Now, when a code is put into delay RAM, is it quantized or compressed? If I were to put in any random code on one cycle into the delay ram and then pull it out on the next, would I get the same code?
No matter which way you cut it, a 24-bit binary number can be used to represent 2^24 entities. Fixed point, floating point, Super Monkey Bananna point, all the representations still revolve around the fact that an n bit binary number can represent 2^24 things, not matter what those things are.
I would be a little concerned if my codes were truncated. Do you use some sort of fully reversable compression?
Also, how can I get my hands on a development board and how much are they (in the US)?
Thanks,
Eli Hughes
