Help me write a code for wavelet transform in VHDL

[navicv]

hello,
i am a little new to vhdl and need some help. i have written c code for haar wavelet transform, i want to implement it in vhdl, to port it onto xilinx fpga board, can anyone guide me as to how to do it. i need this for my M.Tech project.
i tried to consider the matrix as an array of array of integer.
i.e
package mat is
type row is array(o to 7) of integer;
type matrix is array(0 to 7) of row;
end mat;

then i tried to assign values to this matrix, by first writing to a row then putting it into the matrix, but the assignment is not proper.
please help

Re: wavelet transform

Use MATLAB for your implementation it will be better

hi please help me in writing in code.........

Implementing Discrete wavelet transform should be easy, since its plain convolution. So having variable arrays and with some loops , its should be easy.

Ya porting from a matlab code is a good option, but not always an optimized solutions, since xilinx has some constraints.

hi.. im doing image compression by using haar wavelet.. i did it block by block like in the 1st pic. then i conver it into 1Dhaar block and cascade it to form 2D haar.. it is possible to produce compressed image? as i dont have any idea how to insert image to the input

can you be specific as to where you want help in VHDL....if you are doing a convolution...you need to have image row buffers and shift registers to do the convolution process by streaming the pixels to the filter used in the convolution.
