Overview

The C62x/64x FastRTS Library is an optimized, floating-point function library for C programmers using either TMS320C62x or TMS320C64x devices. These routines are typically used in computationally intensive real-time applications where optimal execution speed is critical. By replacing the current floating-point library (RTS) functions with the FastRTS Library, you can achieve execution speeds considerably faster without rewriting existing code.

The release also includes C implementation for a subset of functions available with the FastRTS library. The C codes allow the user to inline these functions and get much improved performance.
