Overview

The Texas Instruments math library is an optimized floating-point math function library for C programmers using TI floating point devices. These routines are typically used in computationally intensive real-time applications where optimal execution speed is critical. By using these routines instead of the routines found in the existing run-time-support libraries, considerably faster execution speeds can be achieved without rewriting existing code. The MATHLIB library includes all the floating-point math routines that are currently provided in the existing run-time-support libraries. These new functions can be called with the current run-time-support library names or the new names included in the math library.

The MATHLIB library includes all the floating-point math routines that are currently provided in the existing run-time-support libraries. These new functions can be called with the current run-time-support library names or the new names included in the math library.

See the benchmarks: DSP core benchmarks

Features
  • Types of functions included:
    • Trigonometric and hyperbolic: Sin, Cos, Tan, Arctan, etc.
    • Power, exponential, and logarithmic
    • Reciprocal
    • Square root
    • Division
  • Natural C Source Code
  • Optimized C code with Intrinsics
  • Hand-coded assembly-optimized routines
  • C-callable routines, which can be inlined and are fully compatible with the TMS320C6000 compiler
  • Routines which accept single sample or vector inputs
  • Provided functions are tested against C model and existing run-time-support functions
  • Benchmarks (cycle and code size)
  • Compiled using Code Generation Tools v7.2.0

Release Information

This is a GA release of the Floating-Point Math Function Library (MATHLIB) for C674x/C66x processors.

MATHLIB contains optimized versions of most floating-point math routines currently provided in existing run-time-support libraries.

MATHLIB RTS override library contains floating-point math routines with same symbol names as in run-time-support library. These routines can be used to replace existing run-time-support library function calls.

The deliverables in this release include a Windows or Linux installation executable for either the C674x or C66x processors. Each executable installs a component package repository, a documentation directory, an Eclipse plugin directory and an expanded component directory structure with component libraries, header files and test examples.
