2021-07-09MLBEDSW-4839: Fix issues with Elementwise IFM/OFM overlapTim Hall
- Fixed typo with not using ifm.mem_type - Fixed bug with using ifm1 properties when only ifm2 is a potential match - Removed restriction on not considering SHL and SHR for overlap - Removed some dead reshape code Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: Id9bcc3c2b3ee9ac7b6276187d3e2f513b4acd4b5
2021-06-22MLBEDSW-4807 Elementwise IFM/OFM overlapJacob Bohlin
Reinstated allowing the IFM and OFM tensor to overlap for Elementwise operations. Signed-off-by: Jacob Bohlin <jacob.bohlin@arm.com> Change-Id: Ide6db7781f3ca7a36c8ff9e3efdc7943a7bf6d7f
2021-06-08MLBEDSW-4602: Fix Deepspeech scale & bias reuse issue.Tim Hall
- Deepspeech reuses identical weights and biases throughout the network. Since biases are now interleaved with weights there is a scaling issue when the ifm scales differ between operations using the same weight and scale tensor. - This commit uses interleaved weights/scales on their first use but separates scales to source memory on subsequent use (if the ifm scale is different).

2020-10-08MLBEDSW-3148: Refactor OperationLouis Verhaard
- op.type is now an enum instead of a string - Removed unused operator codes - Refactored some attributes like npu_block_type, fused_activation_function - Refactored operator index calculation - Refactored a number of operator sets Change-Id: I641f65ee375794b7aec42abc0664251ae37d78e8 Signed-off-by: Louis Verhaard <louis.verhaard@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.

2020-06-18Add 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.
