This talk gives a survey of conventional and modern digital signal
We will describe the architecture of the following conventional DSP
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.
- Texas Instruments: TMS320C3x, TMS320C5x, and TMS320C54x
- Motorola: 56000

From 1993 to 1996, he was a post-doctoral researcher at the
University of California at
Berkeley with the
Ptolemy is a
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
a Senior Member of the IEEE,
and the recipient of a 1997
Science Foundation CAREER Award.
