Figure 9-188 ISS SIMCOP DMA Block DiagramAn external initiator sets up logical channels using the configuration interface.
When a logical channel becomes active, a transfer must be executed. A transfer corresponds to a 2D block of data copied from system memory to SIMCOP memory and vice versa.
A transfer is decomposed into one or multiple transactions by the transaction generation unit.
The scheduler issues transactions when tags are available. There can be one outstanding command per tag on the ISS data interconnect.
