  • DPRIO for embedded hard IP
    Patent number: 7268582
    Abstract: An I/O interface for configuring hard IP embedded in a FPGA includes a register load signal, a CSR initialization signal, and a register data signal. After programming the DPRIO registers, the register data controls the operation of the hard IP block. The interface supports both CSR load mode and the MDIO interface. The user-friendly I/O interface eliminates all requirements on the end-user and is virtually transparent to the end-user.
