From ad1b3d7518429e2d16a2695d9b0bbf81b6565ac9 Mon Sep 17 00:00:00 2001 From: Teresa Charlin Date: Tue, 14 Mar 2023 12:10:28 +0000 Subject: IVGCVSW-7555 Restructure Delegate * New folders created: * common is for common code where TfLite API is not used * classic is for existing delegate implementations * opaque is for new opaque delegate implementation, * tests is for shared between existing Delegate and Opaque Delegate which have test utils to work which delegate to use. * Existing delegate is built to libarmnnDelegate.so and opaque delegate is built as libarmnnOpaqueDelegate.so * Opaque structure is introduced but no API is added yet. * CmakeList.txt and delegate/CMakeList.txt have been modified and 2 new CmakeList.txt added * Rename BUILD_ARMNN_TFLITE_DELEGATE as BUILD_CLASSIC_DELEGATE * Rename BUILD_ARMNN_TFLITE_OPAQUE_DELEGATE as BUILD_OPAQUE_DELEGATE Signed-off-by: Teresa Charlin Change-Id: Ib682b9ad0ac8d8acdc4ec6d9099bb0008a9fe8ed --- delegate/classic/src/SpaceDepth.hpp | 152 ++++++++++++++++++++++++++++++++++++ 1 file changed, 152 insertions(+) create mode 100644 delegate/classic/src/SpaceDepth.hpp (limited to 'delegate/classic/src/SpaceDepth.hpp') diff --git a/delegate/classic/src/SpaceDepth.hpp b/delegate/classic/src/SpaceDepth.hpp new file mode 100644 index 0000000000..cc7f03413d --- /dev/null +++ b/delegate/classic/src/SpaceDepth.hpp @@ -0,0 +1,152 @@ +// +// Copyright © 2022-2023 Arm Ltd and Contributors.
