TMS320 Texas Instruments TMS320 is a blanket name for a series of digital signal processors (DSPs) from Texas Instruments. It was introduced on April 8, 1983 through the TMS32010 processor, which was then the fastest DSP on the market. The processor i ...

DSP family. The standard was first introduced in 1999 and was created to facilitate integration of DSP algorithms into systems without re-engineering cost. The XDAIS standard address the issues of algorithm resource allocation and consumption on a DSP. Algorithms that comply with the standard are tested and awarded an "eXpressDSP-compliant" mark upon successful completion of the test. The standard consists of a set of general rules and guidelines that should be applied to all algorithms. For instance, all XDAIS compliant algorithms must implement an Algorithm Interface, called IALG. For those algorithms utilizing

, the IDMA interface must be implemented. Further, specific rules are provided for each family of TI DSP. Problems are often caused in algorithm by hard-coding access to system resources that are used by other algorithms. XDAIS prohibits the use of this type of hard-coding. Instead, XDAIS requires a standard API for the application to call a particular algorithm class. This API is defined in the

s (video, imaging, speech and audio). A XDAIS developer's kit provides the standard itself, example code, and a demonstration. Benefits of XDAIS over non-standardised approaches include: * Significant reduction in integration time as algorithms do not trash each other's resources * Easy comparison of algorithms from multiple different sources in the same application * Access to broad range of compliant algorithms available from multiple TI DSP Third Parties eliminates need to custom develop complex algorithms * Algorithms work out-of-the-box with eXpressDSP Multimedia Framework Products, such as
