xDAIS and xDM in TI DaVinci

xDAIS: eXpress DSP Algorithm Interoperablility Standard. The interface from algorithm to application is through ‘Algorithm Specific Interface (IMOD)’ and ‘xDAIS Interface (IALG)’. xDAIS privdes the ability to manage resources (memory/DMA).

The IMOD interface provides basic functionality of the algorithm, and the IALG interface takes care of the memory management.

IALG:

• Int (*algNumAlloc) – create Functions
• Int (*algAlloc)
• Int (*algInit)
• void (*algActivate) – Execute Functions
• void (*algDeactive)
• void (*algMoved)
• Int (*algFree) -- Delete

IMOD:

• typedef struct MYDSP_Fxns{
• IALG_Fxns ialg;
• void (*doDSP)();
• }MYDSP_Fxns

xDM is an extension of xDAIS (xDAIS-DM, Digital Media).
