But Codasip offers another option. This is an architecture license – and more – delivered as a source code in the CodAL processor description language.
Many of our customers buy a standard Codasip processor IP product delivered as CodAL source and then use Codasip Studio which enables them to modify it freely. We provide the flexibility to modify both the microarchitecture and the ISA, precisely what one needs to design for differentiation. Customization at the ISA level brings higher performance and optimization. What is more, the power and elegance of the Codasip Studio toolset makes this very easy.
