Scilab for Embedded

 Scilab is an open-source mathematical package similar to Matlab. These applications are commonly used in embedded development to prototype DSP or control algorithms on a PC before porting them to the target hardware. There are several embedded projects using scilab.
"hArtes aims to lay the foundation for a new holistic (end-to-end) approach for complex real-time embedded system design, with the latest algorithm exploration tools and reconfigurable hardware technologies."
The Evidence Scilab/Scicos code generator uses a graphical interface to program a Microchip dsPIC DSC micro-controller board.
