DSPs for image and video processing

摘要

As communications get digital there is an increased use of image and video processing in embedded multimedia applications. Digital signal processors (DSPs) provide excellent computing platforms for these applications not only due to their superior signal processing performance compared to other processor architectures, but also because of the high levels of integration and very low-power consumption. This paper presents an overview of DSP architectures and their advantages for embedded applications. The specific signal processing demands of image and video processing algorithms in these applications and their mapping to DSPs are described. Recent results of successful implementation of two major embedded image and video applications -- digital still cameras and video phones -- on Tl's TMS320C54x DSP series conclude the paper.
