      Change TOSA specification to signless types · fb0284e2
      Eric Kunze authored 
      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.

      Main conformance: Add local bound flag for convolutions · b5b06781
      Dominic Symes authored 
      

Adds a local_bound flag to convolution operations.

If the local_bound flag is true then the output accuracy
for floating-point is measured relative to the
input tensor data local to the particular convolution output.

If the local_bound flag is false then the output accuracy
for floating-point is measured relative to the whole input tensor.
This accuracy measure is the default and more approapriate for
implementations with non local optimizations (such as
transform based fast convolutions).

      Add DIM operator and operations on shape_t values · 830b43b1
      Dominic Symes authored 
      

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.

      Formalise the description of operator argument types · 5333c25b
      Kevin Petit authored 
      

- 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.

      Add TOSA rank requirements to TOSA XML · 42085e36
      Eric Kunze authored 
      

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

      Main inference compliance testing updates · 5b936a3c
      Dominic Symes authored 
      

- Add additional main inference compliance test
data sets for dot product testing in Appendix A.

- Express dot product test criteria in terms of
tensors rather than individual dot products.

- Add per-operation details on test set generation
in Appendix A.

- Clarify compliance vs conformance wording.

- Clarify that the comment in the table of section 1.8.2
on integer saturation applies to the CAST from
floating point to integer operation.

      Fix resize_t enum name · 53e76592
      Kevin Petit authored 
      

resize_t is already used in the type support table for RESIZE, rename
the mode enum to resize_mode_t.

Also add a python function to get an enum object by name to the spec
object.
