Release Information

The Texas Instruments® Digital Signal Processing library is a set of highly optimized functions to perform many common signal processing operations on fixed-point numbers for MSP430™ microcontrollers. This function set is typically utilized for applications where processing-intensive transforms are done in real-time for minimal energy and with very high accuracy. This library’s optimal utilization of the MSP families’ intrinsic hardware for fixed-point math allows for significant performance gains.
