Goals
The goal of the project is to define a high level language that allows description of signal processing algorithms and has the following characteristics:

Allows compact and easy to understand definition of algorithms.
Allows execution and functional verification.
Is HW platform independent.
Allows efficient code generation for various targets (at least DSPs and FPGAs).
Enables future extensions for code generation for multi-core targets in case of computing-intensive algorithms.
Supports code generation for multiple streams.
Supports specification of external interfaces as C functions, and supports inclusion of existing components.
Supports merging, re-grouping, splitting of algorithms and groups of algorithms.
Supports expression of control information handling.

We have developed a prototype compiler that supports C code generation from programs written in this high level language to ANSI C, and we plan to target to a real DSP HW.
