Design provides single-port-to-dual-port SDRAM converter

摘要

In multimedia and video applications, DRAM buffers large frames in the image coding and decoding between an image-sensing device and an image-display device (references 1 and 2). It also plays a key role in image-frame-rate converters by matching the displaying format of the monitor (Reference 3). Accessing dual-port SDRAM is a complex task, especially when two data read or write operations are occurring simultaneously into a single-port SDRAM during high-speed operation.
