2020-09-21MLBEDSW-2816: Fix assert in schedulerDiqing Zhong
- Use non local memory as the base sram usage for a subgraph - Make avoid_for_spilling more generic for all mem configs Change-Id: I99cd30fe6a8ba075d5a70dc2138aa0635afaadb3 Signed-off-by: Diqing Zhong <diqing.zhong@arm.com>
2020-09-17MLBEDSW-2809: Redo the Tensor addressingJacob Bohlin
Added a static class TensorAddressMap that stores all Tensor addresses based on their equivalence_id. Made the "address" field into a property which getter and setter looks up/sets the tensor's address in TensorAddressMap. This makes the references to cpu_tensor/npu_tensor obsolete and they have been removed. Addition to scheduler: avoid SRAM spilling if an op has consumers in other subgraphs. Minor rework in LUTState; it will now assign a unique equivalence_id to the SHRAM lut tensor to avoid issues with addressing. The equivalent checks in LUTState now compares the values of the LUT instead of the the equivalence_id. Updated LUT unit tests accordingly.

2020-08-28MLBEDSW-2889: NHCWB16 format issue at end of subgraphTim Hall
- Processing reshapes at the end of NPU subgraphs selected NHCWB16 tensor format before handing over to the CPU. This commit detects end-of-subgraph during the reshape-consumers compatibility check and chooses NHWC format instead.

2020-08-27[MLBEDSW-2846] Do not use NHCWB16 for reduce_sum int32Fredrik Svedberg
Added checks for not using NHCWB16 for reduce_sum int32 which makes int8/uint8 softmax work. Also enabled softmax graph rewrite by default and fixed a saturation problem. Change-Id: Ic01bd9ece7e5c3edb2900b7915cc747efe9e5760 Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com>
2020-08-26MLBEDSW-2686: Use NPU tensor format for noop reshapes.1.2.0.rc2Tim Hall
- Reshapes that merely add/remove dimensions, rather than re-layout the data need not fall back to NHWC. This commit allows reshapes betweeen NPU operators to use NHCWB16. Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: Ieb7745e586bf324e92e741a04b74caf7285f4b8b

2020-08-14MLBEDSW-2570 Avoid usage of NHCWB16 for some casesPatrik Gustavsson
Avoid usage of NHCWB16 when Stack/Pack/Concat is performed in axis 3, and the "concat start" of each slice to be combined is not a multiple of 16. Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: If3f7b4a3424be3c86fc2dc48e8649ce4c4f49485

2020-06-18Add pre-commit support for sanity checksDiego Russo
Use pre-commit framework [1] to run black and flake8 before the commit. black and flake8 are managed by the pre-commit framework and they can be run manually by the user using `pre-commit run` command. Fix the code base with the help of black and flake8. Fix import statements according to PEP8 guidelines [1] Both tools have the following settings (specified in the pre-commit configuration file): * line length: 120 characters * directory to exclude: ethosu/vela/tflite/ and ethosu/vela/ethos_u55_regs Updated README.md on how to install pre-commit and how to run sanity checks. Pipenv files have been updated including new dependencies for pre-commit.
