2023-08-18Update Custom operator argumentsEric Kunze
CUSTOM operators are still implementation specific, but now have attributes added to identify and namespace the underyling operation. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I8db2fffd0b34958bd8c718633a130941f32f962b
2023-08-17Change TOSA specification to signless typesEric Kunze
Integer inputs and outputs to TOSA operators are now defined as signless values. In most instances the operator will used signed arithmetic as indicated in previous versions of the specification resulting in little functional change to the specification. New attributes have been added to the RESCALE operator to indicate whether the input and output values should be treated as signed or unsigned. Explicit use of static_cast, sign_extend, zero_extend and truncate are added to the pseudocode to avoid ambiguity. Change-Id: I71c67d3e5aeaabc418c768f821fce6ee3eebb65b
2023-08-16Add DIM operator and operations on shape_t valuesDominic Symes
Shape inference derives the shape of tensors in the graph from input shapes. Operations such as RESHAPE may need calculations to derive the new tensor shape. This patch: - Adds a DIM operator to get the size of a tensor in a given axis as a rank 0 tensor of type shape_t - Allows RESHAPE to take a 1D shape tensor as input for the new shape - Allows RESIZE, TILE, PAD to take input sizes based on shape tensors. - Allows ADD, SUB, MUL, INTDIV to operate on rank 0 shape_t tensors - Allows CONCAT to concatenate 0D shape_t tensors to a 1D shape_t tensor - Adds CONST support for shape_t tensors In this version of the specification shape tensors must be resolvable to constants at backend compile time.

2023-07-24COND_IF/WHILE_LOOP: Add nesting level limitDominic Symes
Nesting of if/while is bounded by MAX_NESTING, set accoring to the TOSA level. Change-Id: If9435a143ffa6bd7ba2e46a68542459b3d723b76 Signed-off-by: Dominic Symes <dominic.symes@arm.com>
2023-05-24Formalise the description of operator argument typesKevin Petit
- Standardise the terminology for operator arguments. Argument, Operand, and Parameter were used interchangeably. - Introduce a templatized tensor_t<> type for tensor arguments. Scalars are represented by rank-0 tensors. - Types can be checked with the XSD schema. Signed-off-by: Kevin Petit <kevin.petit@arm.com> Change-Id: Ic57b9387950824e994c5e7f9ec1489c29159b974
2023-05-15Add TOSA rank requirements to TOSA XMLEric Kunze
Adds new optional element to argument 'rank' - Must supply minimum and maximum rank - Integer values or the level based "MAX_RANK" - trailing modifiers allowed for "MAX_RANK" - Displays in a new column in the document - Document generation validates rank against specified shape Change-Id: I507dc51bfe012d3230af43103c6c423a6f1e92b5 Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2023-04-27Move the tensor size limit into the level range definitionDominic Symes
The tensor size in bytes must fit within the level defined size range. Signed-off-by: Dominic Symes <dominic.symes@arm.com> Change-Id: I131e3aa7e8666b4d0093ae8198367f243081da51

2023-03-17SCATTER/GATHER: Replace value_t with in_out_tKevin Petit
Most operators use in_out_t. This removes a special case. Signed-off-by: Kevin Petit <kevin.petit@arm.com> Change-Id: Icfc86f1101d250700677959949bda466519152de
2022-12-09SCATTER/GATHER: Remove redundant definition of index_tKevin Petit
index_t is globally defined as int32_t. Signed-off-by: Kevin Petit <kevin.petit@arm.com> Change-Id: I86ed2d42d488fb8e7630e98e3564f14ba5664f8c
2022-12-09SELECT: Replace use of cmp_t with bool_tKevin Petit
cmp_t is only used in the definition of SELECT and always defined to bool_t. This removes a special case in generators. Signed-off-by: Kevin Petit <kevin.petit@arm.com> Change-Id: I9e7992bbfdf5c7fafdd55df90feb4dcbcdee2972

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.
