When the Wishbone interface is enabled, the FPGA can operate as an accelerator for the RISC-V processor.
|
||||
:numref:`fig_fpga_io_map_wishbone_mode` illustrates the detailed I/O arrangement for the FPGA, where the wishbone bus signals are connected to fixed FPGA I/O locations.
|
||||
|
||||
.. note:: Not all the 115 internal I/Os are used by the Wishbone interface. Especially, the I/O[21:30] are not connected.

.. note:: Not all the 115 internal I/Os are used by the Wishbone interface. Especially, the I/O[21:29] are not connected.
|

|

.. warning:: The FPGA does not contain a Wishbone slave IP. Users have to implement a soft Wishbone slave when use the FPGA as an accelerator.
