3.4.1. Functional Description for the Programmed Input/Output (PIO) Design Example
The Programmed Input/Output (PIO) design example performs memory transfers from a host processor to a target device. In this design example, the host processor performs Memory Read (MemRd) and Memory Write (MemWr) Transaction Layer Packets (TLPs). Note that this design example does not support back-to-back transactions from the host processor since the design is intended to showcase single-dword transactions.
The PIO design example automatically creates the files necessary to simulate and compile in the Quartus® Prime software. The design example covers a wide range of parameters. However, it does not cover all possible parameterizations of the AXI Streaming IP for PCI Express.
This design example supports the following configurations:
