31.2. Feature Description
The mSGDMA provides three configuration structures for handling data transfers between the Avalon® -MM to Avalon® -MM, Avalon® -MM to Avalon® -ST, and Avalon® -ST to Avalon® -MM modes. The sub-core of the mSGDMA is instantiated automatically according to the structure configured for the mSGDMA use model.
The mSGDMA support 32-bit addressing by default. However, the core can support 64-bit addressing when you select Extended Feature Options in the parameter editor. It also supports extended features such as dynamic burst count programming, stride addressing, extended descriptor format (64-bit addressing), and unique sequence number identification for executed descriptor.
