GRAPE-II: a tool for the rapid prototyping of multi-rate asynchronous DSP applications on heterogeneous multiprocessors

The second version of the graphical programming environment (GRAPE) is described. It is intended as a tool for the rapid prototyping of digital signal processing (DSP) application-specific integrated circuits (ASICs) on a multiprocessor. GRAPE-II fully supports multirate and asynchronous DSP applications and heterogeneous target multiprocessors. The extensions that are required to the programming model and the intermediate specification language to support multirate and asynchronous operation are described. The programming model is clarified by an example. The global structure of GRAPE-II is presented. The status of the project is indicated.<
