2022-09-21MLBEDSW-4338 Randomized int16 PAD output diffFredrik Svedberg
The issue was that the AveragePool in these test cases were translated to DepthwiseConv2DBias and int16 convolutions always runs with reduced scale. Fixed so that reduced scale is not used in this case. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: Ice956eabbb37c8aa1991464870006971c6ecec43

2022-09-01MLBEDSW-5029: Output diff for Mean opJohan Alfvén
Fixed three test cases causing output diff compared to the reference kernel for the Mean operator. - If there is a possibility that the accumulator could saturate the Mean op must run CPU - Use correct rounding for the bias term - If a Reshape op is followed by a Mean op, push the Reshape op to the CPU since this cannot be handled by the NPU Signed-off-by: Johan Alfven <johan.alfven@arm.com> Change-Id: I734465730372105821a5e2f73a6a125b9eb7d7f4

2022-08-17MLBEDSW-6645: MLCE: Optimize SRAM usageJohan Alfvén
- When compiling for shared SRAM the old scheduler has an option so that it produces less SRAM than what the new scheduler manages to produce. The old scheduler was able to creates more/longer cascades. In order to improve the new scheduler, the following has been implemented: - Take persistent IFM's into account when creating the min schedule. - Choose longer cascades when it is possible to reduce the total SRAM usage compared to using shorter cascades. - Updated calculation for estimated SRAM usage for elementwise ops.

2022-08-17MLBEDSW-6830: MLCE: Fix assert on concat opJohan Alfvén
- The compiler will assert when compiling a faulty concat op. In the reported use case, there were 3 inputs with shape 1x1x2 but the output shape was 1x1x2 (expected to be 1x1x6) - The solution is to add constraints to the concat operator.

2022-07-23MLBEDSW-6616: ResizeBilinear align corners is incorrectTim Hall
- Fixed align corners support when converting in to upscale and average pool. The problem was due to the wrong ratio ifm to ofm size, causing an scaling factor that was not 2x/4x/8x.

2022-06-27MLBEDSW-6639: Bug fix for evicted FMS in the fast storage allocatorJohan Alfvén
- The fast storage allocator is supposed to add all feature maps that does not fit in SRAM to an evicted list.

2022-06-20MLBEDSW-6347: Improved fast storage allocatorJohan Alfvén
- The fast storage allocator only looked at tensor size, giving priority to larger tensors. The problem with this method is that it does not consider the actual read/write access of the tensor. So, a smaller tensor size can cause higher memory transactions than a bigger one. - The solution is to calculate the read/write access of the tensor and add that score to the decision when deciding where to place the tensors.

2022-05-24MLBEDSW-6593: Issue with finding some config filesRickard Bolin
The argument to the lstrip function is a list of all characters that should be stripped from the beginning of the string, in any order. To remove the actual prefix, check if the string starts with the string instead and then remove that amount of characters.
