Philips PIRAMID System

Philips PIRAMID system is an integrated environment that uses IMEC s CATHEDRAL-II system as a synthesis engine, along with a floorplanner and a module generator (grapMG). See also IMEC s CATHEDRAL-II System.

IMEC s CATHEDRAL-II system is a design-style-specific system for the synthesis of digital signal processing (DSP) chips. CATHEDRAL-II includes transformations, data path synthesis, scheduling, and controller design. See also IMEC s CATHEDRAL-2nd System, IMEC s CATHEDRAL-III System, and Philip s PIRAMID System, which uses the CATHEDRAL-II system as its synthesis engine.
