Hi,
I am interested in an IP core for 2D wavelet compression and decompression. If someone has something that can be synthetized in an fpga it would be great.
Can you u/l it in the 20-day section. Super thanks!

DSPs and fpgas are utterly different devices, but they can both do digital signal processing.
A DSP is a microprocessor optimized for efficient multiply-accumulate loops. You write a program that executes your signal processing (or other) algorithm.

I have never really worked on compression. However, I would like to comment on your second question.

First off, no one fpga supplier's part is going to be better for your application than the others out there. While one supplier part may have some resources that another does not does not mean that its the better choice.
Before you choose a fpga supplier you need to check into the level of support you will recieive from them. I say this because

Hi Dave_LP,
I would also go for the digilent one. The price is great and you get a HUGE fpga for a very low cost.
Don't worry about the OpenSparc, this is just what they support which means the fpga has enough resources to handle the Sparc Soft Core integration.

RAM requirement will depend on number of frames to be stores, its dimension and so on...
Because fpga fabric has very limited RAM, particularly Spartan 3E, you must consider storing frames on external flash ROM.

Just a couple of semi-random thoughts...
Optimize design to best fit the resources of your target fpga. When designing for spartan-3 (LUT4) you might do things a bit different than for spartan-6 (LUT6).
Use best practices that avoid code that makes your HDL synthesize to something that is larger/slower than necessary. Case in point the [url=h

the entire discussion only makes sense if you have built in something in the fpga to handle IO.
I'm guessing you don't have any of that, in which case any attempts at using rs232 will be a one-way street -- from PC to an fpga that has no defined way to listen.
