Description

Texas Instruments TMS320C64x+ IQmath Library is collection of highly optimized and high precision mathematical Function Library for C/C++ programmers to seamlessly port the floating-point algorithm into fixed point code on TMS320C64x+ devices. These routines are typically used in computationally intensive real-time applications where optimal execution speed & high accuracy is critical. By using these routines you can achieve execution speeds considerable faster than equivalent code written in standard ANSI C language. In addition, by providing ready-to-use high precision functions, TI IQmath library can shorten significantly your DSP application development time. The IQmath library release also includes example implementation of complex FFT and FIR kernels using the IQmath kernels.

 

Source Code - Performance for algorithms using IQMath can be further improved by inlining the IQMath kernels. Inlining is a compiler technique that relies on availability of source code for kernels. Compiler can better utilize CPU resources by inserting the kernel source at the location where the function is invoked and then pipelining the processing. To allow users to realize the improved performance, the IQMath release package includes source for many key kernels. To assist users to realize the best performance for the algorithms, TI provides the entire source code for IQMath SW library.
