2023-08-07Allow bias tensors to be broadcastDominic Symes
Bias tensors often have the same value for each channel. To allow for this the number of bias channels, BC, is permitted to be 1 or the output channel size. If BC == 1 then the bias is broadcast.

2023-03-20Check the output shape of broadcast operationsDominic Symes
For an operation that performs broadcast the output shape size must be the maximum of the input shape sizes in each dimension. Additionally, the input dimension size must be 1 whenever an input shape does not match the output shape size in a dimension.

2023-02-24Fix rank limits for various data layout operationsLuke Hutton
This commit removes the maximum rank 4 restriction from REVERSE, SLICE and TILE operations so that the new maximum is now MAX_RANK. In doing so some rank inconsistencies were also cleaned up, including: * Adding a minimum rank to the PAD op description * Adding level limit checks to SLICE and TILE ops * Adding checks for rank(shape1) == rank(shape) for TILE and TRANSPOSE ops * Add tensor_size(shape1) == tensor_size(shape) check for TRANSPOSE * Replace tensor name with shape name in pesudo code where necessary Change-Id: I94bb8ee0b6b720b2ba5a884ce9300dca6281245a Signed-off-by: Luke Hutton <luke.hutton@arm.com>

2022-08-25TRANSPOSED_CONV2D: Invert pad definitionDominic Symes
Increasing output pad values reduces the size of the output region in the old definition. This is counter-intuitive. This patch inverts the sign of the output pad values such that increasing values leads to increasing pad. It also specifies a pad limit range of output pad values that give an output dependent on the whole input.

2022-08-19Machine parsable specificationEric Kunze
This converts portions of the asciidoc specification into an xml document and schema. For the html and pdf outputs, the xml is converted to asciidoc files that are included into the existing specification. The xml allows future automated uses of the tosa specification while maintaining rough compatibility with the existing document. No significant functional changes are included in this change.

2022-06-30Relax limit on input value for RESCALEEric Kunze
The current value is too strict, and can lead to some cases to fail. By making the new value limit between (-1 << shift-1) and (1 << shift-1), we still restrict the input value a range that works for optimized implementations that left shift their values before multiplying.
