1.5. Intel® FPGA Basic Building Blocks
Intel® FPGA Basic Building Blocks (BBBs) are Intel-provided IPs that users can instantiate in their AFU. There are two types of BBBs: software-visible (exposes a register interface and requires software interaction) and software-invisible (does not require software interaction). In both cases, if you are the AFU developer, it is your responsibility to integrate the hardware and software into your AFU.
For more information about BBBs, refer to the " Intel® FPGA Basic Building Blocks (BBB)" web page.
