Sending Array serially

Here's what I need to do, I have an array 16x16, and want to send one by one element to an output. I made an code, but when I put one line, the FPGA use wich was 10% becomes very higher and do not...

A 16 x 16 x 8-bit array requires 2048-bits to implement. Your coding style likely causes the synthesizer to use logic elements to implement these bits.

If you are using an FPGA (not a MAX II CPLD), then the device has RAM blocks of varying sizes. One of those RAMs can be used to store your data, i.e., a 256 x 8-bit RAM block.

Read the handbook for the device you are using, and then use the MegaWizard to generate a RAM block.

Cheers,
