1.8. Performance and Resource Utilization

Because the PCIe protocol stack is implemented in hardened logic, it uses less than 1% of device resources.

The Avalon-MM bridge is implemented in soft logic and functions as a front end to the hardened protocol stack. The following table shows the typical device resource utilization for selected configurations using the current version of the Quartus® Prime software. With the exception of M10K memory blocks, the numbers of ALMs and logic registers in the following tables are rounded up to the nearest 50.

Note: Soft calibration of the transceiver module requires additional logic. The amount of logic required depends on the configuration.
