The Warp was designed by H.T. Kung and his colleagues at Carnegie Mellon University. The Warp is being built and marketed by General Electric and costs about $350K. The Warp has a peak performance of 100 MFLOPS (single precision) and about 40 MFLOPS average. This is about the speed of a Cray 1S. The hardware organization of the Warp is that of a ten cell systolic pipeline. Each cell can execute a different program, so the Warp is a MIMD machine, although it can be used like an SIMD machine if the user desires. Unlike most high speed parallel processors, the Warp comes with an excellent software suite that supports software development and debugging. This includes a compiler for a high level language named W2. Also included is Dr. Jon Webb's image processing library (known as the WEB library) and his Apply language for image processing. The WEB library includes several FFT routines for image processing. Some signal processing operations, like adaptive beam forming, have also been done on the Warp. For more information on the Warp see "The Warp Computer: Architecture, Implementation, and Performance", Marco Annaratone et al, IEEE Trans. on Computers, Dec. 1987, pgs 1523-1538. Ian L.
