Product Development Kit

Our Product Development Kits (PDK) are development environments that enable you to independently integrate your applications into our many technology products, including the BACH module. PDK’s may be composed of:

  • SDK = software development kit, to enable you to program your applications to run on our embedded media operating system (emOS), which is a customized Linux kernel
  • FDK = FPGA development kit, to enable you to integrate custom FPGA logic alongside the COVELOZ FPGA subsystem
  • Hardware reference design, optionally available for you to manufacture your own hardware based on our hardware reference design, complete with specifications, schematics, and layout files
  • Direct customer support
  • Hardware development platform, such as the BACH Development Kit
