XDAIS algorithms
XDAIS or eXpressDsp Algorithm Interoperability Standard is a standard for algorithm development by Texas Instruments for the TMS320 DSP family. The standard was first introduced in 1999 and was created to facilitate integration of DSP algorithm 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 "eXpress DSP-compliant" mark upon successful completion of the test
The standard is comprised of a set of general rules and guidelines that should be applied to all algorithms. For instance, all XDIAS compliant algorithms must use a memory management API, called IALG. For those algorithms utilizing DMA, the IDMA interface must be implemented. Further, specific rules are provide 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. DAIS probits the use of this type of hard-coding. Instread, DIAS requires a standard API for the application to call a particular algorithm class, this. This API is defined in the xDM standard are also referred to as the VISA APIs (video, imaging, speech and audio).
A XDAIS developer's kit provides the standard itself, example code, and a demonstration.
