- Number of channels
- Determines the number of parallel DFE FFT channels that are provided by this instance of the IP core. The default value is 1. The maximum value supported is 8.
- Default maximum point size
- Determines the initial setting for the maximum point size control. This must be a power of two. The default value is 4096, which is the largest supported value. The minimum supported value is 256.
- Support downstream backpressure
- When set to TRUE, the data output can be stalled by the downstream logic
using the
TREADY
signal on the output AXI4-Stream interface. The latency is increased by two clock cycles. When set to FALSE, data output cannot be stalled.
