| Abstract: | TI IQmath Library is a mathematical function library for C/C++programmers to seamlessly port the floating-point algorithm to fixed-point DSP chip TMS320C28x,significantly shortening development time.IQmath Library is mainly applied in high-speed and high-precision real-time calculation,achieving considerably faster execution speed than equivalent code written in standard ANSI C language,which is important for designing demanding real-time control systems. |
