Dear all,
Currently I'm working with Cyclone III for grabbing image from digital output CCD and store the array inside the DDR SDRAM. This is the basic idea of what I'm doing now.
CCD-->data grabber(custom VHDL code)-->SGDMA(??)-->HP DDR SDRAM controller. :rolleyes:
I managed to capture data stream from the CCD. The question is:
1. Do we really need the SGDMA as an interface? I'm quite confuse about the memory descriptor. I know that it provide a continuous packet data transfer. When we set all the SGDMA parameter such as bytes data transfer and the initial memory location, is it this will automatically put the data stream inside the DDR memory according to SGDMA setting?:confused:
