For ADSP-SC59x processors, DAI Routing Unit (DRU) provides all the possible connections across DAIs by interconnecting DAI0 and DAI1 units through a mux as described below,
For every input signal of SRU, there will be a control bit which selects either original signal from the native DAI or its similar signal from the other DAI.
By default, all the native signals are connected to their respective SRU’s i.e SP0_ACLK_O from DAI0 is connected to SP0_ACLK_O input of DAI0’s SRU.
As a part of fully cross-connected DAI Routing unite, following source signals are added to the existing SRU’s source group,
All the source signals of Group-A/B/C/D/E/F from the other DAI are added as source signals to the native Group-A/B/C/D/E/F’s respectively.
This feature provides the flexibility to route all possible source/destination signals across DAI0 and DAI1.
