This talk gives a survey of conventional and modern digital signal processors (DSPs). We will describe the architecture of the following conventional DSP families: We compare conventional DSPs with RISC and with the Texas Instruments TMS320C6x processor family, which is a modern DSP with a very long instruction word architecture. We also compare the TMS320C62x fixed-point processor with the Pentium MMX processor for signal processing applications. We end the talk with several signal and image processing kernels implemented on the C5x and C62x digital signal processors.


Brian L. Evans is an Assistant Professor in the Department of Electrical and Computer Engineering at The University of Texas at Austin, and the Director of the Embedded Signal Processing Laboratory within the Center for Vision and Image Sciences. His research interests include real-time embedded systems; signal, image and video processing systems; system-level design; symbolic computation; and filter design. Dr. Evans has published over 50 refereed conference and journal papers in these fields. He developed and currently teaches EE381K Multidimensional Digital Signal Processing, EE382C Embedded Software Systems, and EE379K Real-Time Digital Signal Processing Laboratory. His B.S.E.E.C.S. (1987) degree is from the Rose-Hulman Institute of Technology, and his M.S.E.E. (1988) and Ph.D.E.E. (1993) degrees are from the Georgia Institute of Technology. From 1993 to 1996, he was a post-doctoral researcher at the University of California at Berkeley with the Ptolemy Project. Ptolemy is a research project and software environment focused on design methodology for signal processing, communications, and controls systems. In addition to Ptolemy, he has played a key role in the development and release of six other computer-aided design frameworks, including the Signals and Systems Pack for Mathematica, which has been on the market since the Fall of 1995. He is an Associate Editor of the IEEE Transactions on Image Processing, a Senior Member of the IEEE, and the recipient of a 1997 National Science Foundation CAREER Award.
