2024-01-28Add missing pseudocode for CONST, CUSTOM, ERF, and IDENTITY operatorsKevin Petit
Signed-off-by: Kevin Petit <kevin.petit@arm.com> Change-Id: Icb824233e5be84ac0eb693459b65441e9ae6c545
2024-01-15Move operator pseudocode to separate filesKevin Petit
This makes it easier to process the pseudocode automatically. Change-Id: I84394192598e589de07d43a7af60b96788e14f86 Signed-off-by: Kevin Petit <kevin.petit@arm.com>
2023-06-21Add ERF activation functionEric Kunze
Defined for floating-point types only. For integer versions, a TABLE should be used. Change-Id: Ieaec6e6eb3227c5dcd9741cddd57426002a8db4d Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2023-05-22Update descriptions for activation functions.Eric Kunze
Provide the mathematical formulas for sigmoid and tanh. Define the operation function for sigmoid and tanh for floating-point numbers. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: Ib949d2e8e06309e5c5292aa0192746ad0f9b1f11
2022-12-05Add Levels defintionDominic Symes
Add definition of Level 1.0. Signed-off-by: Dominic Symes <dominic.symes@arm.com> Change-Id: I1b34ae22396f273cc5ecdf99198fdbece6e2809c
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>
2022-06-17Initial work on floating-point type definitionEric Kunze
Define operations in terms of common floating-point data types. Definitions for the data types are in the introduction. Added a section to describe status of the different profiles. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: Iac57026806acfb7913f40af61176322fb02b7cc1
2022-05-03Specify width of integer typesDominic Symes
Clarify for types previously definded as int the width assumed by the specification. Signed-off-by: Dominic Symes <dominic.symes@arm.com> Change-Id: Ied62d4803a4323a600d33cff09752a76ca48f18d
2021-11-12Use in_out_t when a type is used for input and outputEric Kunze
Also change acc_t to out_t when the value is being used as an output. This should make the argument tables easier to follow. Change-Id: I2a57f3c4eaf937f29da785ff5c11576663a39494
2021-10-28Clarify CLAMP pseudocodeEric Kunze
CLAMP does not do any zero point modification of its clamp limits. Callers to CLAMP should provide values with the zero-point accounted for in the arguments. Change-Id: I27ee468ecd5ab53e33dcbac9c91b705b39e49f96
2021-09-16Clarify range limitations for tensorsEric Kunze
Catch zero and negative sized tensors. Clarify configuration of bool_t in the reference model. int4_t limitations on -8 to stay symmetric around 0. Pad values must be >= 0. Stride,dilation values must be >= 1. Change-Id: Idb6ef740f855912a8340475ba319816f90c9b051 Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2021-04-01Remove RELUN operationDominic Symes
The operation can be implemented directly with CLAMP for int8, int16 or MIN,MAX for int32. Change-Id: I872ec5ee4ee30bb69353f39be12a65307c9b8d0a Signed-off-by: Dominic Symes <dominic.symes@arm.com>
2021-03-11Make pseudocode block tags consistentEric Kunze
They are all now [source,c++] and use ---- as the delimiter. Also made the pseudocode indentation consistent (4 spaces) in the introduction sections. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I1287a60cfeae8b7e3c63b9fc8885b1ebf3d3386d
2021-03-11Adjust pseudocode types to account for zero pointEric Kunze
When reading tensor values with zero point, the returned value has one more bit than the original to account for zero point. Update cases of apply_clip to properly represent the types involved. Change-Id: I60c17b1b244c34b4f04f042807936ae0f282ce93
2021-03-08Consistency cleanupEric Kunze
Attempt to get consistent across the pseudocode. Change the data types to all be intN_t instead of some cases of intN. Use float_t as the general floating point data type. Be consistent on use of the term "floating-point" Move general pseudocode helpers to their own section. Change-Id: Ie77666cd3ee438c71f39c62b9c424fe687b0bb51 Signed-off-by: Eric Kunze <eric.kunze@arm.com>
2021-01-25Remove aint8 typeEric Kunze
The aint8 type represented an asymmetrically quantized range. With the change to move scaling fully into the RESCALE operator, the aint8 and int8 types didn't have significant differences in their use with operators. Unifying to a single data type makes things simpler. Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I3ee89cbdafdc61293ef1f1bec52398d744e716a1
2020-11-29Fix minor spec issuesEric Kunze
Profile for EXP operator TANH table formatting Remove dilation from TRANSPOSE_CONV2D Change-Id: I2a265fecfb25ad997fdc992ad8542000014ac7c0
2020-11-05Clean input argument rank limitationsEric Kunze
Comparison ops, similar to the other elementwise ops, can operate on tensors of any rank. For those operators with rank limitations, make them consistent and remove "dims". Signed-off-by: Eric Kunze <eric.kunze@arm.com> Change-Id: I33eb00122cec4c6625f080f9ed640f1d874fae87
2020-10-22Make rank() consistent across filesDominic Symes
Complete the function naming change from dimensions() to rank(). Fix MATMUL to use apply_add() for additions, consistent with the other operations. Signed-off-by: Dominic Symes <dominic.symes@arm.com> Change-Id: I6ba84cf8b016505e8477b04dd00f2a2bf3194492
