The task of programming concurrent systems is substantially more difficult than the task of programming sequential systems with respect to both correctness and efficiency. The tendency in development of embedded, DSP systems and processors are shifting to multi core and multiprocessor setups as well. The problem of easy concurrency and algorithm development is an important for embedded and DSP systems as well. The goal of this paper is to define and present a high level language that allows description and development of signal processing algorithms. With the usage of a domain specific language, we can create compact and easy to understand definition of algorithms. In the paper the authors present the advantages granted by DSL for DSP applications. The created definitions are hardware independent can be executed and functionally verified. Efficient code can be generated for various targets without porting. The design of the presented DSL allows code generation for multi-core targets in case of computing-intensive algorithms, code generation for multiple streams, threads. Code reuse is supported by merging, re-grouping, and splitting of algorithms and groups of algorithms. |
