From 930fa39c601d1601884ca6ead9f44841f0348f18 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Wed, 26 Jan 2022 10:12:38 +0100 Subject: rfnoc: Update the MTU forwarding property for some blocks Note that the default MTU forwarding policy is ONE_TO_ONE, therefore, it is only strictly necessary to modify the MTU forwarding policy for blocks that route data in a different manner. However, it may be nice to explicitly state the forwarding policy for the benefit of the reader. The following blocks had their policies updated: - addsub: ONE_TO_FAN - duc: ONE_TO_ONE - dmafifo: ONE_TO_ONE - null block: DROP - replay block: DROP - split stream: ONE_TO_FAN - switchboard: ONE_TO_FAN --- host/lib/rfnoc/duc_block_control.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'host/lib/rfnoc/duc_block_control.cpp') diff --git a/host/lib/rfnoc/duc_block_control.cpp b/host/lib/rfnoc/duc_block_control.cpp index 487e4b8ff..95ab9fa71 100644 --- a/host/lib/rfnoc/duc_block_control.cpp +++ b/host/lib/rfnoc/duc_block_control.cpp @@ -72,6 +72,10 @@ public: << " halfbands and " "max CIC interpolation " << _cic_max_interp); + // This line is not strictly necessary, as ONE_TO_ONE is the default. + // We set it make it explicit how this block works.
