2022-10-19Define the index type for tensor co-ordinatesDominic Symes

2022-10-12Change RESIZE border attribute to int16_tEric Kunze
The restriction on border limits in the ERROR_IF is -16 * scale_y_n <= border_y < scale_y_n and scale_y_n <= (1 << 11) Together, these imply -(1 << 15) < border_y < (1 << 11) which fits in 16 bits Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I843f29a5efd8ea3fe559d83d33a3280b39bc7068

2022-08-26RESCALE and POW: remove rank restrictionDominic Symes
Also be consistent to use the term 'rank' rather than 'dims'. Change-Id: Ica827fcfd44e9735da2d1a4ddb8cb1fa04c6479b Signed-off-by: Dominic Symes <dominic.symes@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. Signed-off-by: Dominic Symes <dominic.symes@arm.com> Change-Id: I47ff4ee67942aec9e728f0b42d87d20117f0b97a
2022-08-24Fix cut and paste error for MATMULEric Kunze
tosa.xml had the wrong mode for 16-bit MATMUL. Change-Id: I1feeac9b9a5f61c53d64ae826aa5727da21e5dce Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2022-08-19Change convolution weights to always dynamicEric Kunze
This changes the arguments for the convolution operators to be inputs rather than attributes for all profiles. Change-Id: I9d5fd1ae721271b881179765dc44e966208150da Signed-off-by: Eric Kunze <eric.kunze@arm.com>
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. Change-Id: I7f1f95c527638e270c157d58fcdec6a3510daea5 Signed-off-by: Eric Kunze <eric.kunze@arm.com>

2022-07-08RESIZE: define scale as a ratio of integersEric Kunze
Define scaling factor as a ratio of integers so that output dimensions can be derived from input dimensions without rounding. Change-Id: Iddfd9ff549edf2963bf22047e8641a348cadb35f Signed-off-by: Eric Kunze <eric.kunze@arm.com>
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. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: Ib4f49732e361418884888d398087560da3ccd6e8

2022-06-17Revert RESIZE behvior to the 0.23 versionEric Kunze
The current version does not match the reference model or serialization library. Revert to the old behavior until the model is updated and tested that it works correctly. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I237dc3e94e6c31337073524527da75084ba7b578

2022-06-17Rework the introductionEric Kunze
The information on quantization and numerics was out of date. The tensor access helpers were also consolidated and moved into their own section in the pseudocode chapter. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I472e674ed88f4a3ef379010cf50b13cf8afa5f17

2022-06-02Make the use of inverse in FFT2D definition consistentEric Kunze
The captions for the images used 'direction', instead of 'inverse' which is the attribute name. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I4d8ab9642288efb984d03b7862068e09334ce8f6

2022-05-16Add the uint16_t data typeEric Kunze
An unsigned 16-bit integer data type for use with image networks. Limited to only operating with the RESCALE operator for conversion to signed int16. Zero point can be 0 or 32768 in the RESCALE to allow for no loss of precision (by subtracting 32768), or keeping all values as positive, (zero point=0) with scaling/clipping as defined in the other RESCALE arguments. Change-Id: Id1aebab68fa207f8f8cc235fc3fa5d050307198e Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2022-05-10Mark RESCALE multiplier and scale as refsEric Kunze

2022-04-20Simple fixes to the arguments to CAST and RESCALEKevin Petit
- The input/output types for CAST should be in_t* and out_t* - The shape for the multiplier and shift arguments to RESCALE was in the wrong column Change-Id: I0a3c4ffed15e36f0c4bf8fc9b4a84df5a17a5523 Signed-off-by: Kevin Petit <kevin.petit@arm.com>

2022-01-07Add rudimentary spell check for specificationEric Kunze
We can't easily spell check the entire specification, the pseudocode and operator tables make it unworkable. This adds a simple python script that tries to extract just the description of the operators for checking. It also does a check over the entire license. A custom dictionary is used to contain specification custom words. Change-Id: I74558c03af1506e2970f20b3246d920c2753ca44 Signed-off-by: Eric Kunze <eric.kunze@arm.com>
