hi
i am doing image compression using discrete wavelet transformation. it is a hard ware implementation . i am using spartanII fpga kit. but i dont i know how to send image information in to fpga kit.
does any one know tell me.
thank you

How is the image formed or stored before it gets to the FPGA? Is it
in a RAM chip? Maybe it is a stream?

Without knowning that, it is impossible to say how to import it.

I am also doing a a somewhat similar project.

I am using the camera C3088 http://instruct1.cit.cornell.edu/Courses/ee476/FinalProjects/s2006/jzs3_da65/jzs3_da65/C3088.pdf
which is used by AVRCAM and CMUCAM.

It has 8 data pins which transfer each pixels data.

The FPGA that I am using is up3 Altera Edu Kit which has

Flash Memory Chip - 2MB - TC58FVB106AFT-70
SRAM Memory Chip - 128K bytes - IS61C6416
SDRAM Memory Chip - 8MB - IS42S16400B

How do i transfer the image technically from c3088 camera module to the FPGA supposingly I conenct the 8 data pins directly to the FPGA parallel port and FIFO in the RAM of the FPGA.

Regards,
Sim

You can use ANY input interface that your FPGA kit provides. As we do not

know which these are, we can't help you.

The only thing that your board is guaranteed to have is a JTAG port, and

indeed, this is not the worst solution to download the image to the board.

You say you are using a RAM chip to store the image. Are you aware, that

there are many, many different RAM interfaces out there?

I guess we also can't help you there without further information.

Please learn to ask real questions that acutally can be answered.

For example you could add a link to a description of the FPGA board you are

using to your post.
