Fine grain code synthesis within a block diagram oriented code generation environment

Code generation for a system specified by a block diagram facilitates the fast and efficient evaluation of the design space. As a drawback, automatically generated code includes a certain amount of data management overhead compared to handwritten code, especially When the block diagram includes fine granular structures. The authors present a strategy how to overcome certain types of overhead by introducing a novel code generation approach. While traditional tools are based on a one-to-one correspondence between a block on the block diagram level and a functional kernel on the code synthesis level, one new functional kernel for a group of blocks is generated automatically. Doing so, a maximum of dataflow information available from the block diagram level is employed to organize the kernel in an efficient way, having a regard to the designer's criterion. As a result, reduction in memory consumption and an increased throughput can be achieved jointly.
