Algebraic Signal Processing and Transforms

There are two main projects: SPIRAL and SMART.

SPIRAL is an interdisciplinary project involving a large multi University interdisciplinary team of experts in signal processing, compilers, computer architecture, and artificial intelligence. SPIRAL develops fast implementations of digital signal processing (DSP) algorithms, for example, C or Fortran code, that is optimized for the specific platform of interest. The code that SPIRAL generates automatically is highly competitive. In fact it can be better than the code provided by vendor hand-tuned libraries (follow the link below to SPIRAL and see some of the papers and presentations on SPIRAL).

Major support to SPIRAL has been provided by the DARPA ACMP OPAL Initiative through an ARMY research grant and by an NSF ITR medium size grant.

SMART develops an Algebraic Approach to Digital Signal Processing. While SPIRAL uses the existing fast algorithms developed by researchers through their ingenuity and intuition and then automatically develops implementations for signal processing algorithms, SMART researches ways to automatically "invent" these fast algorithms, in this goal, it is like a "meta"-SPIRAL. Follow the link below for additional information and papers on SMART.

SMART has been supported by two grants from NSF, CISE Division, CCR Program.
