2022-02-02MLBEDSW-3623: Diff on semantic_segmentationRickard Bolin
The root cause of this diff is precision errors caused by rounding several times when performing a resize bilinear upscaling to more than twice the initial size. This is solved by rewriting the algorithm to perform nearest neighbour upscaling to the correct size and then applying one larger average pool instead of several 2x2 pools. Avgpool with padding is limited to kernel size 8x8, which constraints the largest possible bilinear upscaling to 8 times the input size.

This information is otherwise lost in the case when parts of a concatenation are placed in different custom operators resulting in mismatch bewteen NHWC and NHCWB16.

2022-01-24MLBEDSW-5582: MLCE: memory corruption with zero concatTim Hall
- This bug was due to an interaction between multiple Ethos-U custom operators and concatenation of constant tensors - It resulted in different parts of the concatenation being placed in different custom operators - The fix involves places all parts of the concatenation into the same custom operator by switching to a breadth first search in pass packing Signed-off-by: Johan Alfven <johan.alfven@arm.com> Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: Ic47613cfd7bf675b4674dc91d6f9765849ba3130

By not comparing items that have already been compared with each other, the number of iterations for the loop is reduced.

2022-01-12MLBEDSW-5534: Enet_640_640_int8 output diffRickard Bolin
The output diff is caused by not including the kernel dilation when calculating the bottom padding to be used on the last h_stripe. This only shows up when using dedicated_sram since shared_sram does not split into multiple h_stripes and thus uses the padding specified by the skirt instead.

2021-12-20MLBEDSW-5844: Inconsistent calculation of read shapesTim Hall
- This bug causes a regression in the use of unpack and split operators - The bug is due to the read_shapes attribute being an absolute calculation for slice and strided_slice, but a relative one for unpack and split - The fix is to consistently treat the attribute as a shape relative to the read_offset Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: I4504b161be507ea22ca6ee40fbe7808bfe049405
