Premium IP Cores
IOb-Versat: similar to the free version but under a commercial license with IP rights warranted, technical support and customization options. IOb-Versat can be included as a submodule of IOb-SoC to build a software application with acceleration hardware. Being a template accelerator it is less likely to suffer from implementation or timing issues. See on Github. Get a quote.
