From 3f26ef4f9a2d447adb324dd69aec7c49cf7905fc Mon Sep 17 00:00:00 2001 From: Georgios Pinitas Date: Tue, 23 Feb 2021 10:01:33 +0000 Subject: Add tensor related data structures for the new API Adds the following: - TensorDescriptor: which is responsible for holding the information needed to represent a tensor (e.g. shape, dimensions, etc) - Tensor: an aggreate object of a descriptor and a backing memory - TensorPack: A map of tensor that can be passed to operators as inputs/outputs Signed-off-by: Georgios Pinitas Change-Id: I02734ac6ad85700d91d6e73217b4637adbf5d177 Reviewed-on: https://review.mlplatform.org/c/ml/ComputeLibrary/+/5260 Tested-by: Arm Jenkins Comments-Addressed: Arm Jenkins --- src/common/utils/LegacySupport.cpp | 66 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 src/common/utils/LegacySupport.cpp (limited to 'src/common/utils/LegacySupport.cpp') diff --git a/src/common/utils/LegacySupport.cpp b/src/common/utils/LegacySupport.cpp new file mode 100644 index 0000000000..5981c657bd --- /dev/null +++ b/src/common/utils/LegacySupport.cpp @@ -0,0 +1,66 @@ +/* + * Copyright (c) 2021 Arm Limited. + * + * SPDX-License-Identifier: MIT + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to + * deal in the Software without restriction, including without limitation the + * rights to use, copy, modify, merge, publish, distribute, sublicense, and/or + * sell copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
