2022-03-30MLBEDSW-6263: Use separate tensors for double bufferingLouis Verhaard
Uses separate tensors for the individual weight buffers in case of weight double buffering. Each weight buffer tensor gets its own individual live range. Change-Id: I724a8c61a7045615fbd2ed9535663076ac8edd13 Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2022-02-08MLBEDSW-5839: Port of improved spilling behaviourerik.andersson@arm.com
Ported the improved spilling behaviour from Regor into Vela. This replaces use_fast_storage_for_feature_maps with allocate_feature_maps and introduces the class called FastStorageComponentAllocator.

2022-02-07MLBEDSW-6148: Allow overwrite of subgraph inputJohan Alfvén
This change will allow the subgraph's input tensor to be reused/overwritten by the output from an elementwise op if there is only one consumer attached to the input tensor. Signed-off-by: Johan Alfven <johan.alfven@arm.com> Change-Id: I317188af11a5470614770e18dc8973462fd5f21c
2021-10-27MLBEDSW-5450 MLCE: Vela to handle skip TensorFredrik Svedberg
Added checks to avoid merging elementwise op live ranges for subgraph inputs and outputs, which sometimes caused problems when parts of the network run on CPU. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: Id07ab277a205b8550d19a276559f8904b9a4b4be

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).

2021-03-30Performance improvement in tensor allocationLouis Verhaard

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.
