SPIRAL Program Generator for Transforms

What is it?

We provide a web interface to the SPIRAL program generator for linear transforms. You can select the platform, transform, transform size, and several other parameters, and SPIRAL will generate the C code for you, or retrieve it from the database if it was requested before. You can also browse the database below.

The interface is a beta version. This means minor bugs and reduced functionality. Soon, we will include the generation of vector code and parallel code (see the papers below).

You can download an earlier version of the program generator below.

We also provide interfaces to other generators (e.g., Verilog for transforms). See the list "Online Generators" on our main page.

We have made great progress since this paper was published including extensions to parallel platforms, software and hardware.
