Introduction
The MATHLIB package consists of the Texas Instruments optimized kernels for floating point Math algorithms.
Licensing
The licensing information of this library and a complete manifest along with export control information is detailed here [HTML].
Getting Started
The MATHLIB User Guide [USER_GUIDE] provides the documentation and references necessary to begin development on TI's platforms. Currently, Windows build is not supported.
Documentation
Refer to following documentation for further details:
MATHLIB User Guide | Build instructions, API Guide | [USER_GUIDE] |
Software Manifest | Licenses, terms of use | [HTML] |
What's New
API changes from 02_06_01_00:
MATHLIB no longer has <kernel>_init and <kernel>_exec functions. Its replaced with a single API. For example, MATHLIB_cos_init and MATHLIB_cos_exec do not exist anymore. Instead, they are replaced with one API in MATHLIB_cos. The SE0/SA0 settings which was previously a part of MATHLIB_init is now part of MATHLIB_cos.
In order to perform elementwise cosine of a given vector, please call MATHLIB_cos as follows:
MATHLIB_cos(length, in, out); where, 'length' is the size of input vector pointed to by buffer pointer 'in', and 'out' is the pointer to buffer with elementwise cosine of input vector. Please refer to <mathlib root>/examples/<kernel>/<kernel>_example.cpp for more details on how to call the API.
New Kernels:
- MATHLIB_atanh
- MATHLIB_sinh
- MATHLIB_cosh
- MATHLIB_acosh
- MATHLIB_exp10
- MATHLIB_tanh
- MATHLIB_rsqrt

Package Versioning
Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b
[M.m.p.b]
. The table below provides a descriptive reference regarding package version
numbering.
Digit | Meaning | Description |
---|---|---|
1 (M=Major) | Major revision | Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered. |
2 (m=minor) | Minor revision | Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set. |
3 (p=patch) | Patch number | Incremented for all other source code changes. This include any packaging support code. |
4 (b=build) | Build number | Incremented for each release delivery to CM. Reset for any change to M, m or p |
