VLSI Signal Processing Research at Rice University |
The VLSI Signal Processing for Communications Group is presently involved in a number of projects to improve the real-time performance of parallel algorithms for wireless communication systems. The results of these projects are important for the development of the next generation of cellular mobile telephones. Support for this work has been provided by the National Science Foundation, the State of Texas, National Instruments, Texas Instruments, and Nokia Corporation.
Previous work in the group has been in the area of special-purpose architectures for matrix factorizations, including the Singular Value Decomposition (SVD). Computer arithmetic algorithms and their VLSI realizations, especially the CORDIC (Coordinate Rotation Digital Computer) algorithms, have been applied to the SVD. Applications of these architectures have included the inverse kinematics problem for the control of redundant robot manipulators.
