dear all;
I am working on an object tracking algorithm to simulate in xilinx ISE .I need to store at least 5 image frame with the size of (256*256) for R,G and B which I obtained its bmp file in matlab. the data amount seems too large. what kind of memory should I use in xilinx. should I use BRAM?
thanks
 

For that amount of data storage, you will need external ram.
 

you can try storing the images in a text file and read them in you VHDL code if its just needed to simulate your algorithm in xilinx ISE.

if you are planning to do an implementation on a FPGA you need other memory and your BRAM memory is not sufficient to store a single channel of a single image.
 

for a real implementation, you would stream the data through the FPGA, and store it somewhere else (like on a PC).
