  • SPI
  • Register Map
  • ...

• Networking
  • Ethernet
  • PCIe
  • RS232
  • ...

• Communication

The common and networking sub-libraries contain blocks that are required for using various features of the hardware, like the Ethernet, PCIe interfaces to connect to the host computer or other OCRP nodes, and SPI to configure the ADC/DAC and RF cards. Communication and DSP sub-libraries contain blocks that can be used in baseband processing algorithms. Along with these blocks, the OCRP library also contains a framework (OCRP framework)- a set of building blocks interconnected to form a complete radio system, which makes performing experiments on the boards much quicker and easier. The framework specific sub-library consists this OCRP framework, and those blocks that perform specific control functions in the framework.
