2021-02-16Make HillClimb allocation reproducibleFredrik Svedberg
Made HillClimb allocation results reproducible between runs. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I0535947e9cd9c6e0cf896e81b127d93cab54ebc8
2021-02-12MLBEDSW-3808: Ported search allocator to python2.1.0.rc1Louis Verhaard
- Straight port of the C++ implementation to python. - Renamed the allocator from "Search" to "HillClimb" Change-Id: I50797d541f326d0264daf79bf7866aef32350a60 Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>

2020-12-14MLBEDSW-2066 Improve Exception messagesMichael McGeagh
Minor refactoring to use fstrings. Improve Error classes to correctly inherit the base class. Use existing exception classes instead of plain exceptions where it makes sense. Signed-off-by: Michael McGeagh <michael.mcgeagh@arm.com> Change-Id: I0941c04e91010da1db77299517a8e2d896371e77
2020-12-11MLBEDSW-1373: Added search based allocatorLouis Verhaard
Added a new tensor allocator that is based on searching, implemented in C++ (C++11 compatible). Change-Id: Ie96e9fcfc8e6c58d1fa53911f37de290eeba88cf Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2020-11-20vela: Remove and change CLI optionsTim Hall
- Removed unused --show-minimum-possible-allocation - Change --allocation-alignment to --cpu-tensor-alignment Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: I00e367c3190aeea08a3f136332711e9accc85ba3
2020-11-06MLBEDSW-3212 Remove CLI opt ifm-ofm-overlapPatrik Gustavsson
Removed the CLI opt ifm-ofm-overlap Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I23faa0d10c3e71972c543e22e8155086fce73556
2020-10-28MLBEDSW-3212 Enable overlap of elementwise input/outputPatrik Gustavsson
Enable overlap of elementwise input/output Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I6e6f11953319c843c8203bf038f96778df194332
2020-09-25MLBEDSW-2337: Intermediate feature maps in fast storageLouis Verhaard
Attempts to use fast storage for feature maps used in between cascaded passes. This is only relevant for system configurations where feature maps are by default not placed in SRAM, but there is SRAM for fast storage. Change-Id: I207b7cf32cfcb5bea3e6b93c2da1161c4af5221d Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2020-09-17MLBEDSW-2377: Greedy allocator improvementLouis Verhaard
Allocate live ranges with longer life time first. On average this gives better memory usage. Change-Id: Id89e9e36a944169a2f10ce7f6e869397ef0abaf0 Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2020-09-03MLBEDSW-2567: CLI option to specify allocation alignmentJacob Bohlin
Added the CLI option. Only applies to CPU tensors. Added an AllocationError which is raised when Allocation fails. Signed-off-by: Jacob Bohlin <jacob.bohlin@arm.com> Change-Id: I89164dea3ac7b7add7bc40aec2ce8fe50600105d
2020-08-17MLBEDSW-2688: Improved LUT supportLouis Verhaard
- Support for more than one 256-byte LUT in SHRAM - No DMA is performed for a LUT that is already located in SHRAM - Added MemArea.Shram, used for LUT, to avoid false address collision asserts during SRAM tensor allocation - Added read access to LUT in memory access calculation Change-Id: If4d1eded5ed029d253f4f5efb2d80495fc3eac99 Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2020-06-25MLBEDSW-2306 Added more supported mem-cfgsPatrik Gustavsson
Additional supported memory configurations: -Permanent_storage = DRAM -Tensor arena either in DRAM or SRAM Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: I20beb7151e306bfdba540e7c0b2a7b478b4d94e1
2020-06-18MLBEDSW-1941: Bug fix shared weightsLouis Verhaard
If same weight tensor was used with different block configs, errors would occur. Fixed by always cloning weight tensors, using a global weight compression cache and modifying the linear allocator to detect multiple usage of same weight compression. Change-Id: I91ca59176e1c59c66e0ac7a4227f2b5f0b47053f Signed-off-by: Louis Verhaard <louis.verhaard@arm.com>
2020-06-18Add reorder-python-import pre-commit hookDiego Russo
Also updated README.md Change-Id: I118309c61f4d00e8508d6b888c606995490fba39 Signed-off-by: Diego Russo <diego.russo@arm.com>
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.
