converting RAW to RGB

Without going in to your code in detail I can offer the following advice.

http://www.asic-world.com/verilog/

Contains a lot of info on Verilog coding which may be of interest.

The code fragment you posted is a bit out of context, the code following is important to.

always@(posedge iCLK or negedge iRST_n)

begin

if (!iRST_n)

begin

rRed<=0;

rGreen<=0;

rBlue<=0;

end

else if ({mirror_sw,iY_Cont[0],iX_Cont[0]} == 3'b011)

begin

if (iY_Cont == 12'd1)

begin

rRed<=wData1_d1;

Basically this means that the code following the always is executed on a rising edge of iClk (This is the clock) or a falling edge of iRst_n (This is a reset).

The first if(iRST_n) is executed when when iRST_n = 0;

The else part is executed when iClk is rising. This is the synchronous part of the process and controls the inputs to flip flops.

These are just a few pointers and I really suggest that you read a good tutorial on Verilog programming.

Good luck

oh yeah i know how to read verilog, sorry if i didnt make it clear. but my problem is how what the concept is in behind converting raw data into rgb data using verilog. Like for instance if the code goes through alignment of rgb data.

Thanks!

raw is apparently related to the data frame of the camera module. You should consult the respective datasheet, to understand what is converted to RGB video here.

To my opinion, the informative substance of Terasic demonstration code is mostly converging to zero, also in this case.

thanks for the help :)

does anyone know what line_buffer is for?

Line_Buffer L1 (

.clken(iDval),

.clock(iCLK),

.shiftin(iData),

.shiftout(),

.taps2x(wData0),

.taps1x(wData1),

.taps0x(wData2),

);
