2024-01-15Main Conformance: TANH change, SCATTER clarificationDominic Symes
TANH can have cancellation between exp(x) and exp(-x) for small abs(x). To allow for this, a lower bound of 0.5*exp(-normal_fraction<in_out_t>) is set for the error bound. The TANH formula also can contain 4 exp() values, so the error bound is increased to 4 multiplied by the exp() error bound. SCATTER output size K must be as least as great as the number of indices W, as each index is distinct.

2023-11-28REDUCE_SUM: Specify the accumulator typeDominic Symes
For bf16_t data type, REDUCE_SUM is changed to use fp32_t as the accumulator type to be consistent with CONV2D. For other data types the accumulator type is the same as in_out_t (and so no change). Also correct the rank limit text. Update reduction pseudo-code to be consistent with REDUCE_SUM.

2023-11-01Main Conformance: Update EXP, POW precisionDominic Symes
EXP and POW are complex to implement in a precise number of ulp and a more flexible precision is given. Additionally, the test generater S=5 has the bias values changed to zero. If the bias values are non-zero then a bias for all output tensor elements of the channel can affect the dot product bias test. The numeric accuracy helpers are updated for bf16.

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
2023-08-16Main conformance: Add local bound flag for convolutionsDominic Symes
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).

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.

2023-08-07Allow 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.
