Topic: Accelerated Access To Visual Data In Multimedia Applications

Resume: Recent multimedia algorithms require huge amounts of data to be transferred and processed in real-time. Examples are the motion estimation algorithms in MPEG, which require whole blocks of visual data to be accessed randomly and processed as fast as possible. While various designs of processing units, capable of handling arrays of visual data, have been proposed, feeding these units with data is still a substantial performance bottleneck. Traditionally, visual data is stored in scan-line manner in linearly addressable memories. However, in MPEG this data is processed per blocks, which are not aligned according the scan-line scheme. Hence, data reordering is required, which is a time-consuming (i.e., performance restricting) process in conventional memory organizations. To meet the MPEG requirements for high data throughput, new data memory organizations are required.

Keywords: Linear addressing, memory modules, module assignment function, rectangular block addressing, memory buffer, MPEG, VHDL, FPGA.
