2021-12-16MLBEDSW-5554: Place MEAN op exceeding max height with axis==1 on CPURickard Bolin
Signed-off-by: Rickard Bolin <rickard.bolin@arm.com> Change-Id: I87dc5963972a7ef91db467b2ff8e0261e9899372
2021-11-05MLBEDSW-5209 Vela: output diff depthwise with non-zero zero pointsFredrik Svedberg
Fixed by adjusting zero points for ops with int8 IFM and asymmetric weights since the reference does not support asymmetric weights for int8 IFM and ignores the zero points. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I2a206a01a471a53aa864a6a3616aa23d2a5a23c8
2021-10-28MLBEDSW-5440 MLCE: Vela crashing due to mismatch in padding shape in OFMJames Ward
Change convert_pad optimiser to use op.ifm_shapes attribute in place of the fickle op.ifm.shape (which in this case had changed due to the optimised-out reshape) Signed-off-by: James Ward <james.ward@arm.com> Change-Id: I13fbd846ac8d3342afd7844d1041cfa15aaae124
2021-10-13MLBEDSW-5315 MLCE: Vela to handle skip TensorFredrik Svedberg
Removed graph optimizations no longer needed that caused problems with FullyConnected operators running on CPU being consumed by elementwise operators in Vela. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: Ic7e66141ccd5e9aa8f0022c5ab9e7fd1ba3f6786
2021-09-15TOSA: Support for TABLE operator (int8)Patrik Gustavsson
Added support to map TABLE operator to LUT. Limitations: -Only supported for int8 -TABLE input must be constant This also adds the support for TFLite legalisation of Tanh/Sigmoid (int8/uint8).

2021-09-15MLBEDSW-5102 Update removal of memory only operatorsJonas Ohlsson
Memory only operators such as Reshape, Squeeze and ExpandDims are removed in the graph optimiser step. - Added semantic check that memory only operators have same quantisation parameters on ifm/ofm. - Added support for the ExpandDims operator. - Addition and cleanup of related unit tests. - Removed TOSA from the generated SUPPORTED_OPS.md documentation.

Fixed scaling for RELUs with different IFM/OFM scaling. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I0ac96326b3960c0fb025b885e06a259d24b2e684
2021-09-07TOSA: Added RESHAPE, SLICE and CONCATPatrik Gustavsson
Added support for Data layout ops RESHAPE, SLICE and CONCAT. -No support for bool_t -Support limited to Rank <= 4 and N = 1 Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I487ac494b6506a2a6ba947ee758aa193194dd796
2021-09-03TOSA: Added Depthwise supportPatrik Gustavsson
This is mainly to add support for depthwise conv2d with dephmultiplier = 1. (But there are no testcases suited, all I have sourced has depth_multiplier set to 2, which is not supported.) -Added support for depthwise conv2d. -Added support for removing Transpose of constant data -Added support for removing reshape Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I143e6246becfa78fd9f7510af0bf0d6b3fbbf2c7
2021-09-03MLBEDSW-5056 Output diff wav2letter (int16)Fredrik Svedberg
Fixed output diff for wav2letter int16 by correcting the scaling used for LeakyRelu. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I8be1e14c25d223dc6e42c4ec498ff4d3d9de65d7
2021-09-03TOSA: Support for AVGPOOL, MAXPOOL and CONV2DPatrik Gustavsson
Added support for -AVGPOOL and CONV2D with TFLite correspondence -MAXPOOL -additional support for replacing RESCALE ops with avgpool. No support for breaking down tensors over the size supported by NPU. Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I1d2aa50ac30a26283b3e6f1fe88cba1544b7c189
2021-08-25Handle sg input and output for Squeeze operator3.1.0.rc2Jonas Ohlsson
Update to handle the case when the Squeeze Op ifm/ofm are the subgraph ifm/ofm, to facilitate the removal of the Squeeze Op. Adding NOP to maintain the original tensors. Updated pytests for squeeze operator. Signed-off-by: Jonas Ohlsson <jonas.ohlsson@arm.com> Change-Id: I623cae05e696fb16ccf29dedc42fd822601e9fd9
2021-08-23MLBEDSW-4913 Fix inception_v1/v3 output diffJonas Ohlsson
Fix inception_v1/v3 output diffs. Removing the Squeeze operator in the graph optimisation step. The squeeze operator removes dimensions of size 1 from tensor shape. The memory layout is preserved.

2021-07-26MLBEDSW-4892: Fix crash affecting biases without quantization.James Peet
Remove quant_values attribute from Tensor class. It only needs a single values attribute, holding either quantized or unquantized values as appropriate. Change-Id: Ie96f80ac58061b6077e0f7048dc60209fdfbcafa Signed-off-by: James Peet <james.peet@arm.com>
2021-07-08MLBEDSW-4838 Added basic TOSA support.Patrik Gustavsson
Added basic TOSA support, enabling Vela to read and compile a .tosa file corresponding to CONV2D + Rescale + Clamp, and writing it to an optimized .tflite file. The optimized .tflite file, will in this case, hold a commandstream where the Rescale and Clamp has been fused into the CONV2D. The optimized tflite file is not output from Vela. -Added support to read .tosa file into Vela internal structure. - Added tosa_reader.py, tosa_mapper.py and helper files stored under tosa/ - Support for this limited to ~10 ops -Added reader_util.py for functions common for TOSA and TFLite -Added tosa_graph_optimiser.py -Added support to fuse Rescale into convolution -Modified handling for padding -Added support to fuse Clamp to previous op -Added graph_optimiser_util.py -Moved functions common for TOSA/TFLite graph optimization to this file. -Renamed graph_optimiser.py to tflite_graph_optmiser.py -Added separate tosa_supported_operators.py -Added supported_operator_util.py -For functions in common for TOSA/TFLite Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: Ic3c540504ec8c5eb4771397fdc6882050ecf33ab
