Hello i m just writing on my Exams (Diplomwork) and got a Hughe Problem i can t solve by myself. I m working on an Altera FPGA, especially on the NiosII Evaluation Board(NEEK) . I use a part of the MTDB_LCD_TV Project that is delivert and can be downloaded from the Altera Page with the NEEK Board. There is a Function that instanciates the SSRAM and reading all Adresses from their. I need to Read ONE SPECIAL ADRESS and than the next SPECIAL ADRESS for Object recognizing. The Memory contains a Snapshot from a Camera that is saved linewise, so the Coordinates X 100 and Y100 is at Adress 100*100 = 10000 now my Problem is in need to find the Contour of an Object the Coordinates around that Pixel. e.g. Koordinate X99 Y99 is at Adress 99*99 = 9801 and so on... PLEASE HELP ME CAN T GET THAT ONE PIXEL out of the SSRAM :/
Where exactly do you have problems? If the SSRAM is memory mapped as it almost certainly is you can access it from your processor using load and store instructions. Just pay attention to caches that might be present in your system.
The Problem is that i can t access a single Adresse dunno why :/
