Array address translation for SDRAM-based video processing applications

To increase memory bandwidth of Synchronous DRAM (SDRAM) that is commonly employed as external memory in video applications, a memory address translation method is proposed for minimizing the number of overhead cycles needed for row-activations and precharges. The features of SDRAM and memory access patterns of video processing applications are considered to find a suitable address translation. Experimental results show that the proposed method increases the memory bandwidth by 42% over that of the conventional linear translation.
