Gabriel, a second-generation digital signal-processing (DSP) design environment, is described. The Gabriel experimental signal-processing software performs non-real-time algorithm simulations and code synthesis for real-time hardware based on programmable DSPs. Gabriel eases code development for architectures that are not easy targets for conventional compilers. The model of compilation used by Gabriel is discussed at length. Modification of the model to run in real time, target architectures, and scheduling are examined.
