From 05288a2b871ef99f544771621c3bba409b2f70df Mon Sep 17 00:00:00 2001 From: Gian Marco Date: Tue, 21 Nov 2017 10:57:50 +0000 Subject: COMPMID-697 - Rework GEMMLowp interface on OpenCL Reworked the interface of GemmLowp in order to make easy the integration in Android NN - Added support for different output stage - Added validation for both matrix multiplication and output stage - Added bounded relu support in the output stage - Added in32_t bias support - Added optimized path for vector by matrix case This rework is required for: - Convolution quantized - Fully connected quantized Change-Id: I512283d406099cf8c614dd89d0a97ed411143afc Reviewed-on: https://eu-gerrit-1.euhpc.arm.com/110625 Reviewed-by: Georgios Pinitas Tested-by: BSG Visual Compute Jenkins server to access repositories on http://mpd-gerrit.cambridge.arm.com --- .../core/CL/kernels/CLGEMMLowpReductionKernel.h | 99 ++++++++++++++++++++++ 1 file changed, 99 insertions(+) create mode 100644 arm_compute/core/CL/kernels/CLGEMMLowpReductionKernel.h (limited to 'arm_compute/core/CL/kernels/CLGEMMLowpReductionKernel.h') diff --git a/arm_compute/core/CL/kernels/CLGEMMLowpReductionKernel.h b/arm_compute/core/CL/kernels/CLGEMMLowpReductionKernel.h new file mode 100644 index 0000000000..aa0583fe81 --- /dev/null +++ b/arm_compute/core/CL/kernels/CLGEMMLowpReductionKernel.h @@ -0,0 +1,99 @@ +/* + * Copyright (c) 2017 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.
